PA SLx 1x Prism

[ECVMatt]

Well I am not sure if this belongs here or not as there seems to be some confusion about what role this optic plays. It seems to cut the line between a red dot and a 1x scope. Some are starting to feel that 1x prisms address some of the problems associated with red dots such as the need for batteries, star bloom for shooters with astigmatism, retaining a shootable reticle even after an electronic failure.

Anyways it looks like an interesting development more closely associated with red dots than LVPO's and the like. It seems PA is pushing forward with their refinement of the low powered prism sight designed to rival the red dot.

Here is a decent review:

https://thenewrifleman.com/primary-arms-slx-1x-prism-gen-2-can-it-replace-a-red-dot/


What do you guys think, does this have the potential to challenge red dots for rifle and shotgun use or is this just an extention/rip off of the ACGOG or the Bushnell Lil P?

[HeavyDuty]

I very much like the idea, and am curious to see how this one holds up. It’s been interesting seeing how PA has worked their way up the optics food chain.

[DrkBlue]

Well… I pre-ordered one a month ago.

The price point and feature set sound copacetic. I hope the return on investment is there.

You are right, a prism corrects all three potential issues. I don't have the PA but I have three Swampfox Blades (and a Trihawk) and I am a huge fan. In fact, I like them better than red dots. I didn't say they are better, just that I like them better.

Correct me if I'm wrong, but I believe the PA's are made in China (as is Swampfox) if that's a concern. But the Trihawk and 2 of the Blades have very impressive clear glass on par with much higher end optics. I have to admit that one Blade has noticeable "fisheye", which is odd because the others do not. Even so, going from an amorphous blob to a very sharp reticle is a "holy crap" moment. I'm a big fan of prism's.

Biggest drawback is battery life compared to red dots, but changing batteries often is cheap insurance and nothing I'm worried about. And they're still better than Eotech.

[CCT125US]

I'm learning new things here, and I my wallet is not happy. Looks like I need to get up to speed an prisms.

[HeavyDuty]

I haven’t researched 1x prisms in a few years, since the Leopold prismatic was on the market. Do I remember correctly that you can use BUIS through the sight? Although I’m not sure I would bother with the etched reticle.

You can, yes. And I agree, probably not necessary. The point of BUIS, is just that - backup, in case the dot fails completely. Not as much of an issue with etched reticle prisms. If you simply must have BUIS and want to really plan ahead for the optic getting too damaged to see through, then you're better off with offset irons anyway.

[dontshakepandas]

I've never used one, but I do find the idea interesting.

This particular model would be a pass for me because of the 1 MOA adjustments on the reticle, but I've heard they have a model with more precise adjustments coming soon.

[HeavyDuty]

I went ahead and preordered one while the 12% sale was happening (you have to call and have it adjusted, the website won’t take the code on preorders.) I’m not especially worried about 1 MOA adjustments on this type of optic.

[ECVMatt]

I found this on the internet:

75241

The rumored 3x compact with finer adjustments. No firm release date.

[Clusterfrack]

Now if they made a 1x/3x switchable…

Ooooh…

[TicTacticalTimmy]

Anyone know if a magnifier can be used with these?

My feeling is they cannot, but I don't have a logical reason as to exactly why.

[Clusterfrack]

Eye relief isn’t that great. Is there room for a magnifier?

[CCT125US]

What other prism options are worth looking at? Swampfox blade, Vortex Spitfire....

Not needing some HSLD, EOTWAWKI solution.

[Suvorov]

I’ve been very happy with my PA 2X Prism with the ACSS reticle for what that matters.

[Darth_Uno]

Eye relief isn’t that great. Is there room for a magnifier?

Probably not. While I run my red dots as far forward as possible, I've found with prisms you have to adjust for "whatever works for you". To avoid the reticle "swimming" in the FOV, I find I'm placing them as far back as I can. Comparable to how you'd set up an LPVO.

I like my Blades, and I like my Trihawk (fixed 3x); if I wanted to switch magnification rapidly an LPVO is likely a better option.

[DMCutter]

I had a Vortex Spitfire on my MPX for a long time. I wear progressive lenses and with the sight focused, the picture is clearer than with my glasses. Unfortunately, wearing my glasses the focus is wrong, exacerbated by being right handed and left eye dominant. I had a real hard time being able to see my BUIS through it, and the eye box is good but not as good as a red dot. I ended up replacing it with a green 503C which, for me, is more user friendly at 9mm ranges.

[DrkBlue]

So as I get older, Can’t See Shit gets worse. Astigmatism evolution. I have been incrementally buying new prism sights over the last five years. I have the Vortex Spitfire, I have a Primary Arms 3x Prism and recently picked up a Swampfox.

All have pluses and minuses, but the new PA Micro addresses one of my biggest gripes, the weight. The Vortex is very clear, but weighs nearly a pound. It feels much heavier on the rifle, especially as it replaced an Aimpoint Micro on a 5.56. :mad:

The glass in the PA 3x is not that clear. I bought it as a cheapo ACOG. Nowhere near as clear as a proper ACOG. I have it in a box right now.

That Swampfox is a bit big and a bit heavy, but glass is clear and the green reticle is superb. I have less than 200 rounds on it to date, but seems solid.

The PA Micro Prism looks the best yet on paper - 7 oz. and a useable reticle - so I hope the glass is good.

[CCT125US]

DrkBlue

Understand. I've got monovision correction, with astigmatism in my (R) dominant eye. For pistol, I'm very much in the irons camp. Never cared much for dots on rifles either, but dealt with it. Prefer the functionality of a LPVO, but dislike the weight and form factor.

Apparently I've been under a rock, and never explored these new fangled prism optics.

Looking forward to trying out the PA SLx 1x I just ordered..... thanks p-f.

[jandbj]

I’m most curious to hear how these work at the long end of their listed 2”-6” eye relief... all my red dots on AR’s, and a few bolt guns, sit further forward than the set up shown in the review.

[HeavyDuty]

I’m not even sure what I’ll put this on, but I do want to try it out.

[mrozowjj]

I don't think I'll like it for the same reason I don't like most of the ACSS stuff; that chevron is probably too small for my liking.

IMO the concept behind a chevron is you can have the tip to use as a very precise aiming point for slower or longer range shots and the giant chevron to make shooting at close in targets fast. With every ACSS I've tried below a 4x magnification the chevron was so small I couldn't even make out a chevron it just looked like a oval dot to me which IMO removes most of the supposed utility of the reticle.

I emailed Primary Arms to ask what the size of the chevron is on this thing because if it is large enough I might be willing to give it a shot but they told me they don't give out that information so as to prevent people from cloning it. My response was WTF? So I'm going to pass on this one.


IMO the Swampfox Blade nailed the reticle; it's just an over all heavier optic than I'd like.

[Caballoflaco]

I probably won’t be buying one any time soon, but this and especially the upcoming magnified version look like they would make a cool optic minimalist optic for a lever gun.

[Navin Johnson]

FWIW reviews on interweb (mrgunsandgear) implies bigger chevron and more than stated eye relief.

Eh bigger doesn't mean it's big enough to my liking. It's absurd they won't just tell you how big it is on their website. You'd think they'd want the customer to know but they don't... which is offputting to me.

Seems straight forward for a competitor looking to copy the optic to buy a unit and measure the reticle.

Something about this excuse for not providing specs doesn’t make sense.

Yeah I don't get it either. I dug up the email just in case someone thinks I'm fabricating things. I blocked out his name because I'm not trying to get some customer service rep fired:

[Clusterfrack]

I wonder if they don’t know the specs? Just told their Chinese fab shop to make it bigger or something?

[Navin Johnson]

Or..... Whatever size it is once the numbers are bashed around the internet you'll have all kinds of people bitching about the size who've never even looked at it .......so it may not be ideal to give out that information.

It may make a few true shooters unhappy however I think even if the size was told to a person and they knew the size of another exactly the same reticle.....would they be able to judge the difference for themselves without actually looking at it?

I couldn't imagine buying any reticle without actually physically seeing it and looking at targets with it regardless of what anybody else says.

YMMV

[rayrevolver]

I just sold the older version to a friend with astigmatism. So far he is very impressed.

https://www.primaryarms.com/blog/Introducing-the-Primary-Arms-1x-Prism-Scope-With-ACSS-Cyclops-Reticle

This model has a diopter ring, and I *think* you could actually make the reticle bigger at the expense of crispness. But you could turn down the brightness and use the chevron for accuracy or superbright like a red dot.

Not a bad optic, just a little heavy compared to an Aimpoint T-1/T-2 etc.

[frozentundra]

I wonder if they don’t know the specs? Just told their Chinese fab shop to make it bigger or something?

I believe a fellow named Dimitri designs all the ACSS reticles. Trijicon even licenses some of them for ACOG models. Dimitri is a long distance shooter who certainly understands the math behind what he's doing.

I think many people have had somewhat better success using ACSS BDC reticles than some other BDC reticles that wern't designed and vetted extensively by good shooters in the past. I'm not sure what the state of things is in 2021; perhaps the other big players have stepped up their game as well. BDC's obviously have limitations due to all sorts of variables, but I know Dimitri has obsessed over how to acheive the best compromises, and he actually tests the piss out of stuff in the real world with a wide variety of equipment, ammunition, and under variable conditions.

It's probably more like having Brian Litz design your BDC than the marketing department at Leupold.




All that being said, I've personally been underwhelmed with some of the ACSS reticle designs. I'm a fan of thick crossbars for low light situations or even shadowy backgrounds in daylight. They very obviously work better in scopes without illumination. I know the ACSS reticle has illumination, but I still don't trust batteries 100%, let alone my ability to induce user error by not having it adjusted correctly. This article sums up my feeling pretty well with exemplary images.
https://thenewrifleman.com/why-the-german-4-still-rocks/

75454

I think if you are going to an etched reticle for a 1x scope, you may as well etch the damn reticle with a #4 German style on the exterior so it's actually usable without illumination in low light. No one would ever design a non-illuminated hunting reticle that looked like the ACSS, and for good reason.

[frozentundra]

The article linked in post #1 of this thread has a great picture of what the reticle actually looks like in contradistinction to what Primary Arms puts on their website. It gives a better impression of scale. Imagine trying to use this in thick woods with deep shadows. Then imagine it with some hybrid of a German #4 around it.

https://thenewrifleman.com/primary-arms-slx-1x-prism-gen-2-can-it-replace-a-red-dot/

I will probably still buy this optic to replace my red dot. I have pronounced astigmatism in my sight eye, and I could use the diopter to with witness marks to adjust for both corrected and uncorrected vision. That is a pretty big deal to me. I just wish it had cross bars too.

The one thing that doesn't really do is give me a sense of scale. If there was a target or object of known size in the view finder it would give a better impression. As it is the reticle over a blue sky we have no idea if the camear is zoomed in that would make it appear bigger than it is or using a wider angle lens that would make it appear smaller than it is.

The linked article has exactly those types of photos if you are interested. I was referring to the relative size of the reticle compared to the tube of the optic. The manufacturers website has images (not photos) that make the reticle seem much bigger than it actually is.

I decided to hold off and see how these shake out. I cancelled my preorder for now.

[CCT125US]

Shipping notice received.

[ECVMatt]

Mine arrive and I am initially impressed. The glass is clear edge to edge and I was able to focus the reticle to a nice crisp horseshoe. The mount appears to be well thought out and fits the streamlined profile of the optic. It uses the mini-Acog footprint if you have your favorite mount. The illuminated reticle was visible at noon on settings 10-13 for me. However since the reticle is etched on the glass I am not sure if this is as big an issue as some make it out to be.

This one is going on a Ruger PC9 and I would say the reticle is appropriate for the rifle. I took it outside and the reticle is definitely able to give a good aiming point. The optic is not mounted yet, but I did play with the ranging feature and using known distances around my home I can say that it works pretty well. I have a telephone pole at 200 yards and was about to use the height function perfectly.

I have a few weeks before I can get out to the desert for some shooting, but I am happy so far. If my impression remains favorable, I will definitely give the 3x a look for one of my AR's.

Here are some pics for reference only. It is very hard for my camera to get good reticle pictures so the actual reticle is much better using the human eye.

To help with a better idea of the size of the reticle I recruited my son for a quick experiment.

I want to make is very clear the optic is not mounted on a firearm. It is resting on a table. I edited the photo to make it as visible as possible. My camera is not the greatest, that is why I edited the photo. Using the human eye, the reticle is very clear and the chevon is crisp.

My son is 6'4" and about 210 pounds. He is standing at 15 yards.

Initial impressions are good. 100 yard zero was easily achieved. Managed to shoot <MOA, which compared to a red dot seemed easier. Keep in mind my astigmatism and monovision correction. I also am very pleased with the ranging reticle. While I didn't attempt to range with it, I did discover the top line corresponds to POI at 5 yards. I was able to hit the ring numbers on the B8, something I could never do with a red dot. Also seemed as though the open bottom of the horseshoe was POI at 10 yards. Only fired 20 rounds...

Dislike:
The NV settings need to be on the other side of "ON". You have to rotate through those to get to the lower illumination settings.

Likes: It's nice being able to see a precise aiming point on 1x for the first time. Very forgiving eye box. Variety of mount options included. Cost.

[CCT125US]

Without adjusting the diopter, I would estimate from 1.5" to 9", with my vision.

I was going into this with a rather negative mindset. I am looking forward to shooting it more, obviously.

Also, it would have been nice if the ranging portion was illuminated.

[RancidSumo]

Just got one of these in and put it on my rifle. Am hoping this cleans it up a bit for longer-range shooting since dots are pretty big blobs with my eyes.

So far it seems pretty cool, but it definitely has some slight magnification. Will get it to the range this weekend.

I'll echo the forgiving eye box. On the NV settings, you can rotate the knob either way so you can roll through the high intensity instead if you prefer.

[jandbj]

Got to eyeball one of these this past weekend.

Tons of eye relief. I held an AR out at arms length before the edges of the window started closing in on the view through it. Looks like it’d work on a Scout rifle mounted forward of the action... and maybe even on a revolver held at arms length.

And it’s amazing what a difference the etched reticle made with my astigmatism.

My concern was that the horseshoe would be too small to be usable. Opinions?

The more I use this thing, the more I like it. I placed an orange B8 at 100yds, in the shade. It was difficult to see the orange as a defined point of aim. I was able to place the horseshoe around the repair center and shoot 10s. The fact that the Chevron tip is in the exact center of the horseshoe is great. Also, being able to turn off the illumination, and use the etched black has been helpful in several lighting conditions. Things I could never do with a red dot.

I'll be picking up the green Raptor reticle SLx 3x when it comes out in October.

Are you still using the factory mount? That is the only thing I don't care for. I ordered an ADM mount and I'm hoping I can use the PA riser pieces with it - we will see.

[Greg Bell]

I have one of these on my ARX. I am transitioning away from red dots because of my old, crappy eyes. I was able to shoot groups at 100 yards with confidence for the first time in a while because I could actually see the tip of the chevron, not two smudges. Hopefully it holds together.

Had a stage win over 40 shooters at Sundays match using the SLx 1x. That Chevron is a beautiful thing to see. It was very interesting watching shooters get lost in the optic and re-shoot a target, only to skip over others while using LPVO.

I just ordered one of these. After exhausting myself with trying dots and holos. This should work.

My eyes are shit with dots. And apparently worse with holo sights. The Gen 2 Huey and eotech are both great but they are giant red blobs to my eyes. The T2 also blooms bad. The mro so far was best for my eyes. But still not great.

Let me know on base and your height. Looking at the slr because I’m not too worried on the qd. But would like a solid lightweight base to throw under her

I will be very curious to see how this optic works versus a typical rifle-centric sealed tube red dot in wide temperature and humidity swings.
Has anyone used one of the Primary Arms prism scopes in very cold conditions?

[Trukinjp13]

So far initial impressions. The diopter adjustment is awesome. I have a crisp clean reticle. First time I have ever seen that in a 1x. I have some serious astigmatism.

It works in conjunction with triji 3x magnifier as well. Turn illumination off on prism and you get a clean crisp acss reticle. It’s also good with illumination on. But off is precise.

Feels extremely well made. I do not like the mount setup though. I think it’s too busy and heavy. Will indeed be replacing with a SLR most likely.

Hopefully shaking her out this weekend. Along with the fresh build she is riding on.

[Trukinjp13]

Range update. The prism is damn nice. I was shooting into direct sunlight and she is plenty bright. Actually dialed it down to bottom level for more precise reticle while zeroing. Glass is clear and eye relief is dot like. Turning off illum. was great as well. Played with the acss on and off also. I like that the bottom dots do not come on. It keeps a clean chevron and hoarse shoe design while illumination is on. But they are still visible and useful for compensation.

Adjustments are positive and audible. It was damn close at 50 yards for my zero as well. Illumination knob is not easy to turn but once mounted I like that it takes direct effort to adjust.

I ordered the Midwest base. I just do not like the multi piece Chinese made base. It stayed tight throughout and never lost zero. I

With the 3x dialed into the sight it was pretty fun making shots at 50 and being able to id hits through the magnifier.

If you are already vested into the dot/holo life. I do not know of many reasons to switch. It’s nice knowing if battery dies or illumination fails I have a perfectly usable etched reticle still. If you have astigmatism and are tired of getting the bloom and non clear reticle. This is a damn fine option.



Short version. It’s damn nice for the price and I hope it holds up.

What have people been using for QD bases on these? I’ll probably just bolt it up using the supplied base for now until I figure what height works best on my X95. Bobro is my usual go-to.

The supplied base will be great for t&e. With all the options you will be able to set your height like you want. It’s kind of a shit show in mini Acog mounts cowitness. High/low etc.

I believe the prism is basically a low mount Acog. I’m hoping this MI mount will give me lower 1/3.

Did some work on my rig. Changed out the prism mount to the Midwest. The Midwest is nice and I like the one piece aspect. Also it is .1oz lighter [emoji1787]

The Midwest seems to be closer to a 1.7 and now the magnifier lines I’m up better also. Very happy with the improvement.

I have one of the original SLx 1x Prism scopes still sitting in the box. I got it because of my astigmatism and esotropia and can't use red dots without closing my weak side eye, otherwise I just see two images.

One of my AR's (cheap M&P Sport II, but still a darn good rifle) has a Holosun 510C on it, and my other rifle (a new Springfield Saint Victor) has a PA LPVO on it with offset BUIS.

My original intention was to put the SLx 1x Prism on the S&W, but just didnt like the way the BUIS co-witnessed thought it, despite experimenting with absolute, lower 1/3'd, etc. Just didn't like where the height of the scope ended up in relation to the fixed front sight on that rifle, so The Holosun 510C is what ended up on there, and I just close my weak side eye like I do when I use any other optic.

With all that said, that little prism scope is very nice. As others have mentioned, the dopier is fantastic, and allows you to dial in a crystal clear image. I had typed with the idea of getting rid of the fixed front sight on the M&P Sport II and adding a low profile gas block and free-floating hand guard just so I could use the PA prism scope on that rifle, but made sense to simply mount a different optic.

I really wish I had a use for the 1x prism scope because it really is a very nice optic, and I'm sure the newer version is even better.

To clarify, do you find the fixed front in the field of view a distraction or do are you talking about the optic compromising use of the BUIS through the optic ?

You should be able to use the PA Prism scope with the fixed front sight. The U.S. military has used ACOG prism sights with fixed front sights since the 1990s. In service use your optic is your primary sighting system. The ability to use back up iron sights (BUIS) through the optic without removing it is nice but not essential. I would not give up an optic that works well for my eyes on the remote chance of needing BUIS.

If the front sight being in the lower part of the field of view bothers you you could either get and inexpensive riser or acquire a detachable carry handle and mount the PA prism directly to the carry which will give you a "high" mount the same height all the "cool kids" are using for passive aiming. The more upright shooting position is also easier on the neck for those of us with less neck flexibility due to age and/or injury.

It's not the front sight that's distracting since it doesn't bother me at all with The Holosun 510C and a lower 1/3 co-witness. I tried a few different mounts and just didn't like the way the front sight co-witnessed with the prism scope. Not sure if that makes any sense, but even with a lower 1/3rd mount the way the field of view through the prism scope and the front sight lined up was distracting. I don't think it was a true lower 1/3rd co-witness and seemed like it was more somewhere between an absolute and lower 1/3rd.

I would just forget the co-witness through the optic and go with the most effective primary optic.

BUIS are a spare tire. If the optic fails take it off. If you are really worried about it the SLx should fit QD bases for the smaller ACOGs.

It’s not the 1990’s anymore failures of quality optics are uncommon. Uncommon enough the USMC is going to the VCOG 1-8 and the Army is going to the SIG 1-6 LPVO - neither of which allow co-witness and both of which have to be removed to use BUIS.

For sure, and all valid points. It's on a cheap M&P Sport II and it's just a firearm I have that I guess would be used for home defense (I personally prefer my 590A1 for that role) since I'm in CA and thus limited capacity, and live in a really small place, so the shotgun is my primary. The Holosun 510C is an awesome optic, has a huge field of view, shake awake, huge reticle with the circle and dot option, and just works for the intended use of that rifle. I've thought about selling the PA 1x prism scope simply because I don't have anything to mount it on at the moment, but also consider holding onto it because it is a really nice optic, and as mentioned before the diopter really allows for a crystal clear picture. I just didn't care for how it mounted and co-witnessed with that rifle to the point where it was just distracting, but isn't with the Holosun. Sounds weird, yes, but it is what it is!

[HeavyDuty]

My green illuminated SLx 1x showed up yesterday. This morning I popped it on my IWI X95 - the mount PA ships on the sight is actually the perfect height, it cowitnesses with the flip up irons. The only issue I may be having is that the power knob is *extremely* tight. I’ll look at it to see if maybe that’s something the battery chamber lid tightness controls. The other issue is related to me, not the sight - the power position markings are too damn small for me to see. I’ll add a paint dot to the off position.

First impressions are quite favorable. I’m hoping to get to the range soon.

[HCM]

Got to shoot one of these today. Helped a buddy zero it on his Colt 6920. Pretty neat, especially the diopter adjustment. Want one for my A1 clone carry handle.

[Trukinjp13]

I was able to put more rounds down range with it. Very happy with the Midwest mount and it made the pairing with my magnifier that much better. Still very happy with the purchase and the sub 40 degrees did not do anything to affect it. Will know more in another month when it’s freezing.

Actually placed a order for the Glx 2x prism for another setup I’m building. Love the etched reticle and clarity.

The adjuster is tight. But once mounted on the rifle and I’ve used it a bunch it seems easier to turn. The diopter seemed to have a even level of resistance. I also have played with a it lot getting the magnifier and it in sync.

I heard back from PA. I was able to get the diopter cracked loose and smoother but still stiff enough to hold adjustment, and I’m working on the side dial now. I’d rather have these too tight than too loose.

Trukinjp13, are you using the magnifier all the time or is it on a flip mount and just used as needed? I’m getting ready to put together another upper and was thinking red dot instead of another LPVO but my eyes really need magnification and my one experience with “dot+magnifier” was pretty ho-hum (which may have been more about my expectations than the equipment).

I am running a triji micro jobber. Flip to the side. I have probably shot half and half, magnifier and not. I really enjoyed using it at 50 yards on my smaller targets. I could easily see the bull in center. But with 1x that ain’t happening. It adds weight and another part. But I like the fact I can take it off and on.

Well. The 2x Glx has arrived. This little guy is solid. It’s a beast to say the least. Initial impressions are pretty damn good.

Glass is clear

Reticle is crisp

Illumination is good

Eye relief is also great

Knobs are better than 1x. Bigger and clearer numbering. Also has spots in between illumination to turn off.

It feels a little more polished than its Chinese made counterpart. Not saying the 1x is bad at all. Just the little things. The size is bigger indeed but weight is not much more.

I like the 2x. It does not seem to blur up close and is fast. But gives you that small edge over the 1x.

Has a good field of view also. Think 44ft at 100 yards maybe. Not as good as the 1x but good for a magnified optic.

.25 moa adjustable and they are capped. I also like that the cap is machined to adjust the dials.

I need to put rounds down range. This will live on a 13.9 I’m putting together. And think that will make a hell of a pairing. Also bought another Midwest mount for this one.

I like the 1x on the 10.5 and the speed/size of it.

I’d really like to figure out if any of the Bobro bases are the same height as the PA straight riser on base.

Well, my safe answer would be it depends...

For me, and how I plan to use it, likely not.

Unsure of how game would perceive it, and likely would vary from animal to animal.

For home defense, folks could make up all sorts of scenarios where it would or would not matter....

I'm just noting what I saw.

Military Arms Channel just did a review of the Gen 2 1x Cyclops. https://youtu.be/jaUt62cBmoY

He also did a pretty extensive preview of the yet to be released 3x version toward the end of the video. It's very nearly the same size as the 1x. Quite interesting!


I ordered a red 1x 5.56 Cyclops on Black Friday. Somehow FedEx lost my package, and I have been in order purgatory for nearly a month. After a few contacts with Primary Arms (I am always very polite), I finally got in contact with a wonderful not-stupid in the shipping department today. They had sold out of red units, so I wound up with a green one as a replacement. I'm glad I decided to accept the green replacement, because Tim at MAC waxed poetic about his love for these sights to his 1.23 million subscribers today; I bet they'll sell out soon.

The moral of my story it this: If you have trouble with a Primary Arms order, try to speak with Gabby in Shipping as a point of contact if possible.

It would have saved me trouble, and I would have gotten a red replacement unit held on standby if I had talked to her sooner. It's refreshing to talk to someone competent with some authority who can cut some red tape when appropriate.

I’ve been playing with passive aiming with night vision: PVS-14 on the left eye and carbine optic on the right eye. With a T1, I’ve had trouble with parallax/convergence due to trying to resolve different focal planes. With practice, I feel like I could solve the problem. But, so far it’s not easy.

With an etched reticle optic (Elcan Specter DR), I have none of that. The illuminated reticle is always superimposed on the target in the NODS image.

I’m wondering if the PA 1x would be good for this application (other than the visual signature issue).

Interesting. Are you seeing anything through the optic besides the reticle, or is it dark enough that you may as well cap the lens anyway?

I suppose there must be times when your optic eye helps give you depth perception and peripheral field of view even if it's mostly low resolution shadowy information?

Almost dark enough to have the cap on. Definitely can’t see the target.

But I’ve found that the open eye does often provide depth and peripheral information.

If the 1x diopter adjustment works for me as I suspect it will, I'll likely purchase a 2x or 3x and switch between them for different applications with the same rifle. One of the big upsides to these is a variety of good ~2.2 ounce QD mounts that are pretty darn cheap.

You can buy 3 of these things for about the price of a single ACOG or a decent (but heavy) LPVO/mount combo.




Rant:

On a side note: I can't understand why so many people don't like the 1MOA adjustment on the 1x. I wish the 3x had this FEATURE. You can adjust a scope with 1 MOA clicks to a zero of within .5 MOA of POA, and that is a worst case scenario. Probably (90%), it will be mechanically somewhere inside of .5 MOA for windage and .5 MOA for elevation. This is within 2" at 400 yards. Who is actually going to have a rifle/ammo/eyeball/skillset combo capable of exceeding this with a 3x optic on top? The feature to me is that you can mark elevation/windage for a given load/environment, and then with only a click or three you can adjust for many different loads or environmental conditions to match your reticle. I think that's cool and totally outweighs the advantage of silly benchrest competition shooting graduations on a carbine optic.

If you are 1MOA off, just click and you are now perfect. If you are .7 MOA off, click, and you are now whopping .3 MOA off in other direction. If you are truly unlucky, you will be .5 MOA off, and now when you click you will still be .5 MOA off in the opposite direction. How many people are half-MOA shooters with a $5000 bolt gun topped with Schmidt and Bender glass? Am I missing something?

[Trukinjp13]

I wish they would make a 4x version. I would buy it in a heartbeat. Be great on a 16” setup. Have it take the bigger acog mounts and call it good.

3. BUIS. My current 1x is on my X95 which has integral irons that fold into the top rail. I’m wondering if folding 45 degree irons would be appropriate for the Scorpion with a 1x, or overkill?

killer toaster issue

The what now?


EDIT: Never mind. I asked this exact same question a page ago.

[CCT125US]

Brief thoughts on SLx 1x 9mm Gemini

The reticle is smaller than the SLx 1x.

82641

For me and my eyes, the head position / eyebox is less forgiving. Initially I had this mounted above the ejection port, as it comes on the factory riser. I was getting a reduction / zoom out perception of the target. B8 down range, look through optic, target gets smaller??? Adjusted diopter, which was extremely stiff, and had to be initially turned using a wrench with the jaws taped in order not to damage it. Made it slightly better, but still not right, ended up moving the optic as far rearward as possible and that has solved the issue.

82642

Using Fiocchi 158 gr, which is apparently uncommon, I zeroed at 25, which puts the POI about an inch high at 50. The top dot, under the chevron is said to match at 150. For my combo it is dead on at 100. Again, monovision corrected eyes, my gun, my height over bore, my suppressor, extremely uncommon ammo, etc.

82643

I was very close to returning it, and had excellent and fast communication with customer service. I decided to keep it because the BDC reticle has value to me.

Speaking further on the reticle, the top dot is tiny, the bottom dot is even smaller. Visually, the top dot is 3/4 the width of a milk jug at 100 yards, so perhaps 4 MOA, but very precise. Again a 4 MOA black dot at 100 yards. The illumination is only the Chevron and horseshoe. Also noticed that in some lighting, the illumination overpowered the ability to differentiate the BDC. Solution was to turn it off, yes an extra step, but something that can't be done with a red dot, and does allow for a BDC.

Initially not pleased with the Gemini compared to the ACSS GEN2. Some adjusting and experimenting, and I am pleased.

And again, their CS is excellent.

I tried to use a magnifier with the Gen 1 1x Cyclops Prism, and it took drastic adjustments of both diopters, rendering the combo impractical, to get a clear image. Maybe the newer products work better. I've always been a fan of Primary Arms prism optics.

Brief thoughts on SLx 1x 9mm Gemini...

Thank you for writing that up - I have to decide if it’s the optic for me. It’s either this or another Romeo4T for the Scorpion.

[frozentundra]

I finally got my green 1x a little while back. My experience so far has been a mixed bag, although I haven't put many rounds downrange due to extreme cold and lots of snow.

The good:
Size and weight are great.

Love the 1 MOA adjustments! I rough zeroed on 16" BCM ELW-F by firing two rounds at about 25 yards, did the math, made about 14 MOA windage adjustment and about 5 MOA elevation, fired two more rounds to confirm with height over bore being accounted for. Worked as expected, and got me to 100 yards for a 3 round group. I only needed about 2 MOA adjustment at 100 for windage and I think 3 for elevation. Fired a 5 round group to confirm with no surprises. Easy.

I messed with the diopter and found that, while I couldn't fully focus the optic to my uncorrected vision (crazy astigmatism), I could get it good enough to easily make hits within 6" circle at 100, in failing light, on a low-viz target (cardboard box). The same diopter setting was quite decent with my glasses too. I would be hard pressed to do this with a red dot without my glasses on in low light. I still need to see if I can mark positions for corrected vs uncorrected vision and switch between them.

There are a variety of decent QD mounts available, and I've got one on the way.

Close range, inside house distances, seemed very red dot like.


The Meh:
It was poor light, getting near dusk, overcast, with ambient temperature below zero. It was hard to see the low contrast targets I brought. I had some 2" blue painter's tape crossed on roughly 12" brown cardboard boxes. I could make out the blue tape when looking over the gun, but when I got behind the optic, the image was dimmed enough that I couldn't make out the tape, so I had to just hold in the center of the target silhouette; I was loosing a lot of detail optically, even with both eyes open. I was surprised by severity of this, but didn't bring other optics for comparison, so don't know what, if anything, I was loosing in the balance. Will have to get a RDO and LPVO out for a taste test some evening.

I noticed that, for my individual vision, it's not the same as a red dot when driving the gun to target. I think there is specific terminology around the issue I am unfamiliar with, and I seem to recall reading that it affects different people differently. When I aim using occluded aiming (Bindon Aiming Concept or whatever), if I occlude the optic tube, aim to a target at 50 meters, then remove the occlusion, I am no longer centered on target where I thought I was. By contrast, red dot sights don't seem to have this effect for me, or at least not nearly to the same degree. For me, the effect is pronounced enough that it even feels weird driving the gun to targets at certain ranges. I feel like I have to make a small correction to account for this phenomena as I pick up the sight on target. I will need to do a lot more messing around and see if my brain calibrates for this like with a new pair of glasses.




So far I am cautiously optimistic.

I was told by a PA rep that they do not make a kill flash for the 1x. I have also seen them available for sale on PA....

I do not think the killer toaster issue is worth any worry, just an observation that could, possibly matter in a very specific set of circumstances.

Regarding the SLx 1x 9mm Gemini. I have one that I need to provide some thoughts on.

I can confirm the killflash does fit my 1x.

[HeavyDuty]

PA is having one of their periodic 12% off sales. I was able to use this and a few bonus bucks vouchers to order the green 9mm 1x plus killflash for $91, it’ll go on my Scorpion SBR.

[JHC]

I believe a fellow named Dimitri designs all the ACSS reticles. Trijicon even licenses some of them for ACOG models. Dimitri is a long distance shooter who certainly understands the math behind what he's doing.

I think many people have had somewhat better success using ACSS BDC reticles than some other BDC reticles that wern't designed and vetted extensively by good shooters in the past. I'm not sure what the state of things is in 2021; perhaps the other big players have stepped up their game as well. BDC's obviously have limitations due to all sorts of variables, but I know Dimitri has obsessed over how to acheive the best compromises, and he actually tests the piss out of stuff in the real world with a wide variety of equipment, ammunition, and under variable conditions.

It's probably more like having Brian Litz design your BDC than the marketing department at Leupold.




All that being said, I've personally been underwhelmed with some of the ACSS reticle designs. I'm a fan of thick crossbars for low light situations or even shadowy backgrounds in daylight. They very obviously work better in scopes without illumination. I know the ACSS reticle has illumination, but I still don't trust batteries 100%, let alone my ability to induce user error by not having it adjusted correctly. This article sums up my feeling pretty well with exemplary images.

I think if you are going to an etched reticle for a 1x scope, you may as well etch the damn reticle with a #4 German style on the exterior so it's actually usable without illumination in low light. No one would ever design a non-illuminated hunting reticle that looked like the ACSS, and for good reason.

I've drilled a German #4 with my scope set to #1 a fair bit in daylight and it was fast as hell 25 and under. One doesn't use the reticle to "aim" with any more that one is supposed to focus on the dots. Center the target in those fat black bars and rip. Seems like blasphemy but that's what it looks like to having also shot with RDS sights on carbines.

[HeavyDuty]

The 9mm green 1x arrived today. I spent time in meetings (no camera) playing around with different height bases on the Scorpion and settled on the low cantilever 1.41” configuration. I’d like to put BUIS on this since the CZ originals are a little low and neck crunchy, but I don’t want absolute cowitness - IIRC standard AR irons are 1.4” above the rail. I seem to recall HK-416 sights are a little lower? I’m also wondering if a set of 45 degree BUIS is practical - XS makes a low profile fixed set, and there are many low profile folders.

I have a feeling I’ll be trying the 2x next on a carbine.

[Lex Luthier]

I was lucky and got a hold of a green-reticle 5.56mm version from a fellow P-F member.

My impressions are favorable & I look forward to learning how to use it. The picture was done with an old Canon digital Elph camera set in macro mode with the lens placed where my eye would most likely end up with a proper stock placement and neck extension, at about 4" from the diopter.
Brightness setting is at "4" (out of 13)
I find that with my usual glasses, the tip of the chevron is quite clear, but the camera does not quite get there.
You can see that the glass has a little darkness and is not quite as clear; the target wall is approximately 3' from the muzzle. Relief is good for me at 3" to 8"; farther out and the trianglular shadows from the lens mechanism
start to encroach into the view.

I expect to sight it in this weekend and see how it does.

(ETA: the above image does have the accessory PA Killflash installed. When fitted, you will only give yourself away to your decepticon toaster within a very small range of motion, and then only when a light source is shining through the diopter end of the unit. )

[Trukinjp13]

Piggybacking here. But I finally finished building a new upper and could install the 2x onto this. So far it’s just sort of mock up until the finishing touches come. But I added the lower spacer to the Midwest qd mount. Seats height around 1.75”ish. Perfect for me. This is going to get its own dedicated lightweight lower now. But wanted to get a feel for it.

I am now going to do the same with my 1x. Adding the spacer to it as I’m planning on ditching the magnifier that’s behind it for now anyways.

I have been so impressed with the GLx 2x. I may try the 3x on this 13.9 and move the 2x to my shortie. The GLx is a smidge above the SLx IMO though. Just the small details mainly.

I think the SLx 1x/3x will be very durable though. So far my 1x has been fine in sub zero temps and what not.

Almost half the weight (8oz vs 15oz) and shorter than the ACOG 4x with an extra 1.2" of eye relief? What kind of voodoo is this?

I realize the PA is a 3x vs the ACOG 4x and the ACOG has the fiber optic but this is getting damn close to "seems too good to be true" category.

I also love the Romeo 4T ballistic reticle. I had an ACOG+RMR on my rifles for a while but I realized that setup is biased towards mid range shooting and it made CQB shooting slower... so since 90% of the time my shooting is inside 200 yards I got the Romeo 4T and I leave just the circle dot on. If I ever need to shoot 200+ I can add the extra dots and throw a magnifier behind it.

I understand the appeal and advantages of the 1-6x or 1-8x LVPOs but the extra weight vs a red dot isn't really worth it to me most of the time.

Ilya Koshkin (the Dark Lord of Optics on Youtube and social media) is an optical physicist who works in the electro-optical field. He's also a shooter and gun nerd. On one of his podcasts he explained that prism optics get heavy very fast as magnification increases. Apparently that is why we don't see any higher power prism optics; they would be stupid heavy compared to a 6 or 8x LPVO. This is assuming I understood him correctly.

The 1.5X ACOG is only about 5 oz or so, but field of view is only 39 ft @ 100 yds. I think something that also makes the 4x ACOG heavy is that it has a field of view of 37 ft, just about as wide as the 1.5, or the new crop of 3x compact prisms, and has a larger 32mm objective lens for low light performance. The 3x ACOG is actually lighter than the new PA 3x at 7.7 oz, even though it has a relatively large 30mm objective lens, but it's field of view is quite small by comparison (only 19ft @ 100yds), which is probably how they shaved off the weight there. The new PA 3x lists 38 ft @ 100 yds, and 8 oz weight, but I'll bet the objective lens is only about 20mm (I didn't see it listed), which will give up low light performance in favor of field of view. The 1x cyclops objective lens is only 17mm.

There must be a significant weight penalty for FOV as well as magnifactaion in the prism. I think perhaps the new crop of 3X prism sights may be saving weight at the cost of lower magnification compared to the 4x, lower light transmission by using small objective lenses, and keeping the FOV only equal that of the 4x ACOG. This is just my uneducated speculation, but I suspect low-light optical performance is what is being thrown by the wayside in these new compact prism optics.

I have no idea how much difference this will make in real world applications.

[Trukinjp13]

The eye relief is very underrated. Mine have a hell of a lot more than the numbers they put up. That’s one thing I really like about em. And it’s easy to pickup the reticle in awkward positions.

You know, it's funny- I looked over a Vortex Spitfire 1x at Cabelas before deciding to pull the trigger on the PA Micro.
I think the Vortex glass might be just a tad clearer, but I like the PA reticle better, and I found the PA eye relief was more forgiving, too.

Probably too late to be helpful, but I'm still very happy with mine. Shake awake has worked perfectly every time and the reticle is very easy to pick up in full outdoor light and not too much in indoor light. I see it being the permanent solution for my main 16" AR, which after years of small adjustments I think I'm done tweaking.

[CCT125US]

theJanitor missed the question as well, but I now have 2 of the 1x, 2 of the 3x, and a GLx 2x. They just plain work for me.

I'm pretty impressed with the 3x optic so far. If it holds up I invision me getting a few. They seem like a really well thought out gp optic

[Oldherkpilot]

I recently bought a Colt lightweight carbine and decided try to keep it light. I have a 1-4 LPVO on my other 16" gun but it also has a medium contour barrel and is heavy enough that I've considered installing an undercarriage! For the new rifle, I mounted a Primary Arms SLx 1x prism optic and an SLx 3x micro magnifier on a flip to side mount. After a couple hundred rounds, I am very pleased with the arrangement. In hindsight, I normally ran the 1-4 either on 1 or 4, so 1 or 3 power with the PAs works well and is much quicked to change from one to the other. I like the notion of the etched reticle in case of batttery failure. The Cyclops reticle is fine for me and makes the offset for close in shots a breeze.

I've got a few of these and they have been reliable so far. Recently, I noticed the green versions are advertising 45k battery life versus 29k on the red.
The 1 moa adjustment of the reticle is limiting but for a unitary scope perhaps of little import.

I have the ranging reticle version of this magnifier behind an Sig Romeo 5. It's worked well with my astigmatism. The adjustment ring on it allowed me to turn the magnified smudge into a bundle of dots, which basically makes turns it back to a red dot to my special eyes. 1x looks like a normal red dot to me.

The eye relief is close. Almost 4x ACOG close. This isn't a big deal to me because if I'm using the 3x I probably have time to get into a stable shooting position. This is also a 7.5" truck gun, lol.

I have the 1.5x ACOG ACSS and the 4X ACOG ACSS. This magnifier seems to be more similar to the 4x ACOG with how close you need to be. The 1.5x ACOG has eye relief for days.

Overall, would recommend. The PA flip to side mount is very solid and tactile also.

However…PA sucked me in today with their awesome SOLGW sale and now I have a 14.5” complete upper on the way. Decided to add the 3x to my order because…FREE shipping on my entire order with the purchase of a PA optic. :rolleyes:

Now I need two MI or ADM quick mounts so I can rotate between the 1x and 3x.

Feel free to stage an intervention!!

[HeavyDuty]

My SLx 3x arrived today. I’m impressed - like others I can see this becoming a standard magnified optic for me. This one is earmarked for a new LaRue upper that will get here at some point. Like davisj, I need to figure out a QD mount of the correct height, I’m thinking the ADM.

I wish I could find something better than the flimsy bikini cover, though - it’s pretty snug once you mount the killflash.

My replacement 3x arrived and mounted right up on the MI mount. I’m impressed so far just LARPing around, but need to get some range time in. (The first 3x turned out to be someone’s return, PA immediately exchanged it.)

I never did update the thread with my mount and lens cover findings.

I used the MI TA33/TA44 ACOG mount I linked above, it works well. I also found two Butler Creek flip-up covers that work so long as you use PA’s ARD, both are eye objective style (without the little thumb lever) - 02A front, 05 rear.

I agree. I recently mounted mine up and took it out to zero. Eyebox was no factor and the glass is really, really clear. Love the FAST horseshoe reticle for close and the inverted V for distance. The V allowed me to be more precise than with a standard dot. Was able to reliably ring the 10” plates @ 200, and that, with a crunchy AUG trigger.

Planning to order the 3x compact version as a contender for permanent duty on the AUG.

Not CCT125US but I’m using MI throw lever ACOG mounts on my three 3x prisms.

I'm hoping Steiner will jump on this train and release some really small prism sights. The main reason being that they would put a daylight bright fiber LED dot in it with a crosshair reticle and their superior glass in it. The thing that keeps me away from Vortex and PA prisms is the lack of stadia lines on the etched reticle, that's a non starter for me in a magnified optic. The weight of the current ones keeps me away, I'd rather run an LPVO. The Vortex Razor and PST Gen 2 1-6x have the perfect reticle.

While there is not a detent position, it will turn off in between settings. With the auto-live, some may feel it's not necessary, but I find it useful based on target coloration.

Doesn't the flash hider eliminate the glow?

[theJanitor]

The ARD? Somewhat but not enough when so much lights gets emitted from the front. I also don't prefer running ARD's anyway. If you get mud or dirt embedded in the ARD, it's super hard to clean. Squirting it with some water doesn't really clean it out as the dirt/mud is trapped in the honeycomb

I haven't been following this thread, just read through it though.

I know it is about the PA SLx, but seems to have also morphed into a magnified prismatic optic discussion.

Years ago I bought a Burris AR332. It worked well at intermediate ranges, but sucked at short ranges. I discovered that if I turned on the power (never did at 100 to 300 yards) and flipped down the front cover it worked great, didn't even know the optic was occluded. It has the Ballistic CQ reticle which is usable on this prismatic scope, unlike on their AR-1X.

It also has mounts for a smaller RDS on top and 90 degrees both sides. Plus the Burris lifetime guarantee.

The reticle worked for me, YMMV. Burris has discontinued them, but the have them on Optics Planet for $189.99 - about half of what I paid almost a decade ago.

I also have the Burris AR-1X Prismatic (which has also been discontinued but is still for sale online) it has the Ballistic CQ reticle, which IMO is worthless on a 1X. I still have it on a M4 FSB rifle using a Troy Battlesight on the rear with a 1/3 mount for the AR-1X.

I replaced the AR-1X, which had been on my primary training/range rifle, with a Vortex Spitfire. Much better.

Prismatics are the way to go for old guys.

Prismatics are the way to go for old guys.

My experience is leading me to the same conclusion. I haven’t tried using my 3xes with front cover down, I just did some whittling this morning on one of my Butler Creek front caps and am much happier with the fit. Something to try.

I think my pair of SLx 3x scopes have found homes - one on my new 12” Larue upper (Mark cries) and the other on my Ruger American 5.56 Ranch.

I've had the 1x for several months now and really like it. It started out on my 16" SG556, but for now it's on my SBR'd P556...

This seems to be the most active general prismatic scope thread.

Does anyone have experience with the current Vortex Spitfire AR 1x?

Primary Arms just released a newer, slimmer version in their GLX line, with supposedly improved eye relief and compatible with more micro prism mounts. Red and green illumination available. No idea if this one has Japanese glass or not.

… and still with no flip-ups.

Can this get as low as an aimpoint micro?

[ECVMatt]

I have one on the way, so I will be the guinea pig. I’ve had very good luck with Primary Arms optics in the past. I’m hopeful this one is good as well. It should get here in time for next weekend‘s shooting mission in the desert.

[HeavyDuty]

Their newer prisms have been impressive - I’d be curious to see what it’s like side by side with the last generation 1x.

[Redhat]

I got the SLx 1x mounted on my carbine last week and put 60 rds of 55 gr ball through the rig this week. I fired all rds at 50m for grouping / playing around with the adjustments and trying to get familiar with the green ACSS reticle. Coming from an aimpoint this reticle was a new thing for me. I was disappointed with my groups but I think I may have been using the wrong type target. It was also my first time firing this carbine (or any AR since about 2010).

I'll be going back out next week with some different brands and weights of ammo to see if I improve. With that in mind, what type targets do you guys like for zeroing at 50 and 100?

[ECVMatt]

I have an old 1 X mounted on a 10/22. I can definitely compare the two.

[ECVMatt]

I wanted to post a quick update after getting some time on the GLx 1X.

I was able to compare it to my older SLx 1x and I would say it is worth the upgrade. The eye relief on the GLx is great. I put it on my Ruger PC carbine and could place it anywhere on the top rail. The Glx was easy to focus and the image is crisp and clear. For me, it was an improvement over the SLx. I do want to make it clear I don't stare through optics for hours on end looking for edge to edge clarity or brightness. I used the optic on my rifle and did not notice any limitations imposed by the GLx. It is fast, light, and clear for my troglodyte standards.

It was very easy to sight in the optic and the adjustments were tactile and repeatable. The optic was daytime bright at the top two brightness setting at high noon in the Mojave desert. As the day passed, we shot both into the direction of the sun and away. It was very easy to see the red chevron and circle. I tried to get pics, but could not get the reticle in focus. The sight is equally usable with the reticle not illuminated.

There were some things I did not like. If you are planning on using the buttons often they can be a pain to locate. You have to look at them to manipulate them. Primary Arms did a good job of making them unobtrusive however. If a person is using the Auto-live feature this might not be an issue at all.

I also found the range finder basically useless when looking into the desert. The marks are small and get lost in the bushes and rocks. I could see how this might work if a person was standing next to a light colored building, but in the field, it would be difficult to use this feature. On a 9mm carbine, it becomes a moot point, but worth mentioning.

Lastly the chevron is small. I would have liked it be a bit bigger. This is a personal preference.

By the end of the day we had about 350 rounds through the Ruger and no drama with the sight. I did shoot it at night and was able to find a setting that was visible with my x300 but not washed out.

Overall I am very pleased and will leave it on the Ruger. I like the clear aiming point and the being able to use the sight with or without the reticle illuminated.

There is a much better review over on AR15.com with some good pics.

Please let me know if you have any specific questions I did not cover.

Quick OT question: Are was supposed to be able to use prism sights like red dots i.e., with both eyes. open? I've had a Swampfox prism for a few years and despite playing around with various eye reliefs, I can't for the life of me use it with both eyes open. I do like the very crisp reticle.

ETA: The Swampfox is 1X.

[CCT125US]

Tensaw yes

Yes. If you're falling back to closing an eye, you need more dry practice. As suggested above, occluding the front lens of the optic can help.

Thanks. Hmmm,…. This maybe need to be a separate thread (I haven’t read all of this one). No issues using rifle/pistol dots both eyes open, but the prism gives me two target images. Maybe this can be attributed to the comparatively long tube (4” or so) of my optic? I’ll try the occlusion thing though. Would love to be able to use it with both eyes.

Sorry, answered before coffee and didn't even notice that this was the SLx1 thread. But my answer is still the same. If you're target focused, you will see only one target.

It seems there is some optical shift in these. From C_DOES video review (https://youtu.be/ioPhnZcnQs8?t=1210):


as Distortion free as they are however there is one thing that I talked about in my 50,000 subscriber special
which showcases both of these with me using them side by side on the Range but if you were to focus on a target with
your naked eye and then bring the scope up it will look like the target is now slightly higher through the scope than
where it was with your naked eye

[ECVMatt]

I saw similar comments over on AR15.com. I did not notice this shooting the rifle outside in the daylight. Again, I’m not an optical expert but rather more of a “Busch Light” user. The optic was very easy to sight in and I didn’t notice a shift looking back and forth through the optic and at the target. It was also very easy to get hits on steel targets. I would simply raise the rifle, place the circle in the center, and get hits exactly where I was aiming. This is something to definitely be aware of, however.

So I'm redoing my son's 10/22. i got a new chassis coming soon, and I want to move his PA SLX over to it and add a PA 3x magnifier. I haven't bought the magnifier or a mount, but I do have a couple questions.

- Are there a set of mounts (ADM, etc) that will line up both the SLX and the magnifier properly? I'm not loving the PA mounts, and I'm willing to buy BOTH the optic and mag mount

- Does the PA magnifier share the same footprint as the Eotech G33?
