CZ Scorpion Evo thread

[Rtorres]

After SBRing my Scorpion I found I really didn’t care a whole lot for the factory stock, especially after I changed out the sights. I recently picked up a Magpul Zhukov stock on a HB Industries adapter, and am liking it much better so far. LOP is fractionally less than the CZ stock, and it folds flat to the right side. I’m not sure if it can be reliably fired when folded, at least not in the shortest position - not really a concern for me.

I’m looking cor that foregrip for my 3+ micro. Thanks

So I just joined the club! Picked my green scorpion up yesterday.

In keeping with the Holiday Spirit - "Now I Have a Machine Gun! Ho! Ho! Ho!"

From reading this thread it seems that single point sling is the way to go? I'm firmly in the 2-point world so a little out of my element. Will a 2-point work? What single point is working well? V-Tac? Vickers?

I went ahead an ordered a SB Brace despite looming "non-legislative legislation" as well as the HB Industries safety delete and trigger spring kit.

I ended up going with a two point adjustable sling for my APC9 after talking about it with HCM. I’m mostly familiar with the VTAC and VCAS slings but decided to try the Edgar Sherman Designs sling after HCM had good things to say about it. Plus the shorty PCC is much lighter than any of my ARs have been when fully kitted out so I was willing to give an thinner, non-padded sling a try. ESD was blowing out the gen 1 slings for $30-$35 so I picked one up. As far as I can tell the only difference between the 1.0 and the current generation, called the ESD sling, is that the elastic band that lets you tuck the sling in for storage has a little pull tab that makes tucking the excess in easier. It looks like a snow pattern 1.0 sling is still in stock for $35. I like it a lot so far. The pull tab is easy to find and grab onto. It functions the same way as a VTAC or VCAS: pull towards you to loosen and push away to tighten.

Question regarding the forward hand stop on the EVO3. I tend to use a "thumb forward" grip on a rifle. When handling my scorpion and dry firing (have yet to get it to the range) I am noticing that my thumb will rest along side the flash hider slightly. This has me concerned that it might be hit by gasses from the gun when fired similar to using such a grip on a revolver. Has anyone experienced this? Other than concentrate on keeping my thumb away from the muzzle any other suggestions?

Mine is a SBR, so I was able to use a substantial HK-style vertical grip and handstop combination. Before I did that, I had a MagPul handstop far enough back to protect my hands. There isn’t a lot of space on these.

[Joe in PNG]

I put a TLR-7 on as a handstop myself.

Gen 1 down to $729 some places.

I saw that too (of course right after I purchased mine). Palmetto says “Clearance” along with their price so that has me wondering if CZ is going to be dropping them soon in favor of the 3+? Be a shame but I see they have already discontinued the carbine.

[Suvorov]

So an update on my experience with the EVO3 so far.

In short - I’m really liking this little gun. About 200 rounds down the pipe including a mixture of ball and hollow points. I went a little wild with accessories before the fact (which is something I always tell people NOT to do). Turns out I have no real need for the safety delete as the standard safety does not contact my trigger finger when firing and the extended paddle release (Strike Industries) seems to be more trouble than it is worth - the paddle is too low for how I grip the magazine and it is prone to accidentally releasing the magazine due to sling entanglement so I ended up re-installing the factory mag release. The MagPul pistol grip as well the HB Industries trigger springs were good enhancements. I topped it with a Vortex Crossfire II optic with the low mount that gives me a good co-witness and keeps the low profile of the gun. Finally I found a V-Tac 2-point sling that wasn’t being used and purposed it for the EVO3. A HK style front clip and a quick release sling plugged into the pistol brace works great both in the traditional sling uses and for pushing out under tension when firing without the brace extended.

While I tend to agree that the rifle length PCCs come up short versus rifles in a personal defense application, this EVO pistol is so compact it really is more a semi-automatic sub gun than a PCC. Very tempted to move it into the HD role. With that, what defensive ammo are people running? I have 124+P and 127 +P+ as my standard defensive rounds. It seems that 16inch PCCs tend to favor the 147 grain rounds as the increased velocity causes the lighter bullets to fragment early, but I would think that mid weight bullets should do fine with the modest velocity increase of the 7.7 inch EVO3 barrel. Anyone have any numbers on this?

V-Tac? Vickers?I tried a BFG 221 sling in single point configuration, and hated it, even though I had my barrel chopped to 5", and switched back to a two-point sling.

[Joe in PNG]

So, with the upcoming brace ban- does anyone have the 16"+ carbine barrels in stock?

[Suvorov]

I tried to zero the gun a couple days ago and had some issues with flyers. Most were just a couple inches off but a few were a foot or more at 25 yards. I noted that the optic was a little loose* so I tightened it down and got an acceptable zero with both optic and irons. The loose optic explained the small flyers but the big ones? When cleaning the gun I noticed what looked like a split barrel! Horrified I removed the flash hider to find this.

100963
100964

The barrel, muzzle and crown were all in good shape but the thread protector had apparently worked itself loose and had been hit a few times by rounds, splitting it and wedging it inside the compensator. A brief google search reviled that I am not the first person to experience this, there is a fairly large thread on Reddit about it and a YouTube video where a dude shoots the front end of the compensator off. I was able to get the thread protector free of the comp and went about contacting CZ-USA about the issue. They wanted me to send the gun back to them but given that everything looks good (I will confirm it zero's well when I get the chance) I asked them if they could just send me a replacement thread protector. They didn't have any in stock but said they would send me one when they get some more.

So, just a quick heads up to go ahead and check the thread protector on your guns to make sure it is secured before it loosens itself. Frankly I think the protector is superfluous as the compensator covers the 1/2" x 28 threads. I can definitely understand why Kalashnikov went with the LH thread for the AK.


* To make my day even crappier I overtightend the base screw at the range so when I went home to remount the optic I found that I had snapped the base screw. Fortunately I was able to cannibalize the parts needed from the taller base Vortex shipped. A quick email to Vortex resulted in replacement parts for both bases less than a week after the fact (still shouldn't have happened in the first place but.....)

[HeavyDuty]

I think I’m at the final configuration here*. I started with the OEM stock, then tried a Zhukov stock on HBI adapter (pic is upthread) - but I really wanted to try a Haga Defense modified ACR. The Haga finally came back into stock a few months ago and I grabbed one. I finally got to the range with it over the weekend - it’s a winner. I’ll be selling off the Zhukov, I think. The ACR fits me better, has great adjustable cheekweld and definitely reduces the effect of recoil due to the straight line design compared to the CZ stock - with the original stock it was a cheek slapper.

* Still needs a KeyMicro FH for when I finally get a Wolfman

Do you still have the OEM stock?

[HeavyDuty]

Yep! I was planning to hang on to it since it’s OEM. It’s more compact and lighter, just not as comfortable to shoot.

Damn it. KeyMicro FH ordered.

That’s really tempting but I already have no shortage of 22LR understudies. I wonder if the stocks will be lower grade copies of the original or the real deal?

Frankly- I would have rather them re-release the EVO Carbine….

It would be great if they don't simply go the Umarex understudy route and make it into a viable 22LR platform that stands on its own.

Exactly! The EVO 3s design is such making a .22 version should prove extremely easy and relatively cheap.

I got the new CZ Scorpion Evo 3Plus last week. Took it to the range and zeroed the iron sights @25yds.
111264

It was shooting high right initially and I really had to drift waaay left on the rear peep. The irons are DAMNED nice on this thing. I was amazed at how good they were with just the pistol rest. No stock or brace.

Here’s the final volley after zeroing. The 3-5 flyers were ALL trigger related. If you zoom in on the pasters, you can see how I walked it in. 😎. (That friggin’ 9-10 lb pull really did a job on my arthritic trigger finger.) 🤷🤦🤣. Literally fatigued my finger/hand to repeatedly pull that biotch. I have a Timney CZ trigger due tomorrow. That should fix that issue. I also got the folding charger to save my knuckles sum grief. 😉

I hope the trigger install Tut’s on the YouTubes are accurate & relevant to THIS model as most I’ve found are at least 3 years old or older.

The Magpul mags with the cut out fit the 3 and 3+ and work great if anyone needs mags.

The lack of backwards mag compatibility with the EVO3 is the prime reason I am looking for an old EVO carbine instead of one of the new ones.

But this is good to know that MagPul has updated their design.

I wish they could have figured it out to go both ways.

Timney Trigger arrived. Along with the. Manticore Arms folding charger. Wasn’t too intimidating getting them installed.
The Timney instructions are a little confusing if you’re like me & not entirely certain what’s what in a firearm’s innards. 🤣

Anyway,.. It appears I was successful. Safety’s working as it should. Nice positive clicks when activated. The trigger is almost, not quite, but Almost, Scary light compared to the OEM. I went with the 3-3.5 lb pull weight and the reset is SHORT AF! 😳

I was planning on hitting the range with it tomorrow if everything went as planned,… Now I’m thinking I’ll take a drive over there tonight put a few rounds through it and make sure it’s working properly.

Here are a few pics just for comparison of what I took out and what I put back in 😎

The Timney trigger is awesome! Scorpion ran like a champ today.
The new Trigger doesn’t trigger the Arthritis, So good to go. 👍🏻😎



Anyone know of a good, affordable prism optic. One that will lower 1/3 Co-Witness with the CZ’s OEM irons? Either that or one with a high enough mount that I can see thru/under to use the buis? I’m looking for an alternative to getting another RDS. Something not prone to blooming with my astigmatism. 🤷*♂️

You can get pretty decent prism optics from Vortex or Primary Arms, but you can't cowitness with a prism optic.

Well, I caved, couldn't pass up under $700 OTD (under $600 with the rebate). So, now, WTF is up with the irons on this spacegun? They seem well constructed, but I'm not sure what optic, if any, on what mount, will allow their use in a lower 1/3 or absolute co-witness. My go-to PCC optic (Holosun 503CU) blocks the irons completely either in the tall mount or the direct-to-rail mount.

Also, is there a source for 3+ ready magazines besides magpul? Don't mind having one long-stick (that's what she said!), but I wouldn't mind a couple of 10-rounders either, or an OEM 30-round mag.

Thanks for saving me reading through 28 pages!

It is skeletonized so that the middle is empty, and I can use the factory sights off of that. I would think that the 503CU should work given that the middle is also empty, based on pics? That being said, my irons are quite hard to use, since I use a Zhukov stock with a SideProject Link, and the stock sits much more inline than the OEM stock.

I’m using a Vortex Crossfire with the low base and it gives me a good lower third co-witness. I really like the overall setup which is why I didn’t go the Zhukov route.

Keep an eye on midwayusa for factory mags. They had 30 round 3+ mags on sale for $17 2 months ago but have since jacked the price back up.

Imma think I'm going to SBR my S1 Evo3, but looks like I've got to also make it 922R compliant too. Which means I've got to swap out 6 parts. So far, I've got the Apex grip installed, so that's one.
CZ Custom has a US made disconnector and what's marked as a "USA made factory trigger", so that would be two & three.

Now for four & five, I'm pondering the Strike Handguard with faux suppressor. I'm wondering if the faux can would apply as muzzle device?

Finally, I'd like to find a good folding or sliding stock that doesn't cost a fortune.

I’ve fooled around with a few different stocks on my SBRed Scorpion - the factory, a Zhukov and a ACR. I settled on the ACR, but the Zhukov was a close second. If you want one, it’s in my mental sell pile.

After more ponderage & looking- the easy but spendy option would be just replacing the trigger with the Timney unit. That gets me 4 parts, with the grip & stock counting for the full count.

One of the reasons I'm liking the idea of just dropping in the Timney unit is not having to mess around with the notoriously tight Evo barrel, or getting any number of special nut sockets.

[WobblyPossum]

Understood, which brings me to a question I’ve always had about 922(r). At what point is the “assembly” complete? Is it a one time thing like when you first reassemble your pistol into an SBR after your Form 1 is approved? Or is it a continuously refreshing thing like every time you put the gun back together after you break it down for cleaning, does that count as you “assembled” the rifle?

[HeavyDuty]

I decided the ACR stock that I mounted to raise the cheek and allow use of AR height sights was too heavy, so today I switched back to the CZ stock and low sights with no RDO for the moment. I didn’t weigh it before, but the difference is substantial. If I leave it this way I’ll need to figure out a rear QD attachment.

It used to have a R4T on a 39mm Reptilia DOT. I’d like to keep BUIS capability with the lower CZ sights.

The cupboards are bare of extra RDOs at the moment, though.
