Mount for 30mm

[breakingtime91]

Hey everyone, I am at a loss. I got a Steiner 30mm p4xi scope (1-4) and I am not sure what mount I should get for my BCM middie.


Any suggestions? Thinking I want QD, hard to get that out of my head.

Pass on the QD, they all have issues.

I like Geissele, Nightforce, Badger, Knight's Armament. All have cross bolts and horizontally split rings.

If I were buying today, I'd go with a Geissele, probably standard cantilever length and definitely 20MOA cant.

I have two Nightforces, 30 and 34mm, both excellent, both return to zero, no problems.

What does the 20moa can’t do?

20 MOA cant is unnecessary for a 1-4x on a 5.56 AR...this isn’t a long range precision build here. I like Geissele optic mounts but they are pricey.

OP, check out the Aero Precision Ultralight mounts. Have one on my KAC and one on my Colt Trooper. If you choose these go for the Extended or SPR mount lengths. I have the SPR length on both of my ARs.

20MOA cant is not necessary, but being zeroed closer to mechanical center is good and there is zero reason not to use a canted base.

It cants the scope 20 MOA so you can dial for elevation for long range shooting. Long range IE 1,000+ yards. Completely unnecessary especially with a 1-4x on an AR

I’m running a Larue with my accupoint, but there are probably better options now for QD.

I did pick up one one of the Aero Precision ultralight mounts, and it’s a great value. No complaints.

M2, why 20 MOA cant for a 1-4 LPVO?

For a non-QD option, Vortex just released a precision cantilevered mount. About $190 retail. I bought one for a 34mm scope and it was well made.

For QD, I have a Bobro extended mount that's worked well.

If you run your AR stock short (like 1-2 clicks out from collapsed) you're going to want a mount that allows for more eye relief which the above two options provide.

If this is a duty gun or some kind of gun you're going to take into harms way definitely go for higher quality. Otherwise you can probably get away with a more budget oriented cantilever mount (SWFA has one for $60/ Vortex has a budget mount for $99). The P4xi is a nice scope but it isn't exactly a precision optic.

I have been using AERO precision mounts.

Bobro if you want qd.

Geissele if you want non qd.

Aero if you want non qd cheap and light.

Check my reviews if your interested.

I have my Nightforce 1-4 in a 20MOA mount because all Nightforce Unimounts are 20MOA.

Regardless, zeroed at 100 or 200 yards it will put the scope close to mechanical center or even a little down. It really doesn't matter on a 1-4, but the mount may not always be for a 1-4. It just doesn't make sense to me to not use a canted base unless you're stacking NODs with your optic.

I have no advice to give. I'm just posting to let you know that my first thought when I saw the thread title was "Awesome! Someone's bolting a GAU-8 Avenger to their SUV!"

Can you go into more detail on that? Based on recommendations, it seems to me that lots of people are using QD mounts.

Larue pinches the wrong part of the rail, and when adjusted to not move, they usually aren't QD anymore.

Bobros don't get tight enough and they walk on the rail until they fall apart, and they will.

ADM is either too tight or too loose.

Aimpoint QRP won't get tight enough, their lever mount is fragile and doesn't return to zero that well.

That's about all I have experience with. Lots of people will defend their favorite QD mount, usually religiously, but put the stock on the ground and bump the optic with the side of your fist and watch it walk on the rail.

I started down that path when a USMC FI said my Larue mount was junk, just like all their issued Larue mounts. He used my mount to demonstrate why to not use that type of thing. I checked my 3 or 4 other Larue mounts and they all did it.

[Beat Trash]

Any thoughts on the Midwest Industry WD mount? DSG runes a package deal with the Steiner 1-4 combined with the MI mount. It’s not a deal if the mount is not serviceable though.

[El Cid]

I've been very pleased with my ADM 30mm mounts. They are QD but I've had zero issues in thousands of rounds. The 5.56 was used in a Defoor Advanced Carbine class and the 7.62 in a F2S Heavy Carbine class. Both rifles get used in local matches and other classes. RTZ has been true on the rare occasion I remove the glass. I have a 3rd ADM mount currently holding a Strike Eagle on an upper but I haven't had time to shoot it much.

If I was buying a mount today I'd go with Geissele because everything that man does is amazing.

This is coming from the same guy that said you can’t get a decent 1911 for under $3k. Not trying to start anything, but those are some bold claims. I don’t remember ever seeing an issue with Bobro or ADM.

I do agree with Voodoo’s post - Bobro, Geissele, or Aero are probably the best options in those categories. Personally, my P4 is sitting in an ADM mount which I have been pleased with, but it is just a place holder until Scalarworks releases their 30mm mount.

You may not have seen issues with those mounts, but I have. They're great until someone shows you why they're not. I'll go a step further and say that the Larue scope mounts are the poorest design I've ever seen with the vertically split rings that are separate from the base along with the little cam levers that pinch the corner of the rail. But they still work. It's more a testament to the paralell sides and recoil lugs on the 1913 rail than it is an awesome mount.

You want a 1911 that will run with a Glock 17 or a 6920? You're not going to get it for a grand, and there's not really anything between $750-$1000 and $3K besides Dan Wesson, and it ain't gonna hang with a G17. That's just a non-negotiable fact of life. But that $3K still won't get you as far as Glock 19. But don't take my word for it, ask some Marines and the FBI what they replaced their 1911s with.

Re QD:. Ask yourself what you need it for. Do you need toolless removal in the field? If so, get QD.

Do you need good return to zero after removal? If so, do your research. IME, a non QD mount and a cheap torque driver(like weaver) has produced good RTZ results. Some QD mounts have good RTZ, others don't.

Personally I tend to not F' with my optic once it is truly zeroed because a dialed in rifle+optic is something that just shouldn't be messed with. I want robust mounts without unnecessary weight. Currently happy with my NF mount, but the Geisseles I've interacted with are really nice as well. Had an Aero mount, it was feather light, but I lost zero after the rifle was tipped over onto a linoleum floor. Not sure if it was the Vortex PST or the Aero mount, but the combo lost zero. I've since subjected my NF NXS + NF mount to much worse and never seen any shift.

[M2CattleCo]

And you won't.

Even without a torque wrench a cross bolted mount will return to zero fine. I've removed and reinstalled many scopes in rings and one piece mounts that do fine.

Disagree there, that last part is a whole different argument. But that is way off topic in this thread.

OP, one thing I will say is that since I’ve gotten my LPVO, I’ve been strongly debating not only the need for QD but the need for BUIS as well. Since it has an etched reticle, even if the battery dies it is still far more usable to me than irons. The only thing that would make me want either is if the lens was somehow broken to the point that I couldn’t use it. And even then, if I don’t have backup irons, QD is kind of a waste. If that somehow did manage to happen, I have a feeling that I’d be looking at a different option than ditching the optic, throwing up the irons, and continuing on that way. YMMV, since it really depends what you’re doing with that gun.

Exactly my thinking. My Z6i has crosshairs I can use. But if the optic is damaged to where it's obscured I can quickly remove it and use irons. I fiddled with offset irons but am not a fan. They are basically useless if I have to go support side of cover.

[Crews]

I’ve personally used Bobro, ADM, and Larue QD mounts. All have been pretty decent at returning to zero, and held up fine for hunting, getting beat up on the atv and other such foolery. After using all of them, I have come to the conclusion that it’s just one more complexity that is liable to break at the worst moment possible, even though they never did.
Gimme a regular ole’ crossbolt and a wheeler fatwrench please... it’s Badger or Nightforce unimounts these days for me.

Also, worth noting the recent discussions around vertically-split rings being no bueno for scopes. Trivial at best for a 1-4, but it was compelling enough for me to rule out Larue and ADM for that reason alone.
