Five years later, and you are still helping CZ owners. THANK YOU so much for this video! My son and I just got our first suppressor (Silencerco Omega 36M) and needed exactly this video today to get it mounted. Now we're off to the desert for some silent plinking fun!
I noticed my thread protector is cracked all the way through. It looks like it came loose under the compensator and got hit but it's too wedged in there to get it out. I emailed CZ to ask about a replacement and they flat out said go to HBI and buy one. Thanks CZ, very cool.

Excellent! I looked high and low for something that explained the "dual threading" of the CZ EVO. THANK YOU!!!! Now I can go about ruining my new toy with full confidence that I have some vague idea of what I'm getting myself into. ;) Again, thanks for posting this!
Funny is stumbled on this video I just bought a scorpion and was wondering what the 2 items were that came in the box. Now I know thank you very much for that.
I'm dying to order your micro compensator, I know many others waiting for that little guy too. Edit: I got it, put it on a glock 22 9mm conversion barrel and it seemed like it actually helped quite a bit. My groups were actually looking a lot better. It did change the report of the pistol a little bit too, It sounds a bit meaner than the pop it made before.
Timely and informative. Just got my stamp and I was wondering about putting the suppressor on. I also got the gun cerakoted in a German flecktarn pattern. Cool. I bought the barrel removal wrench from you in case I need it someday.
My thread protector got loose and the bullets were hitting it. I found out after my bullets were nowhere on target. Took it all out and ordered the Evo Ultra Comp muzzle device.
Have you noticed if the PIC rail on the PS for forend where the front sight goes is raised at all? I’ve heard it angles up which causes the sight to be off.
I had a gunsmith install your guys' MLok handguard on my Evo 3. The way he gave the gun back to me there is nothing on the end of the barrell, just a wider section of threads that then goes to a smaller section of threads. Is there something I need to do in order to install a new or the original muzzle device? I'm no gunsmith and don't want to shoot the gun until I have a proper muzzle device back on the gun.
It sounds like you have a Gen 2 Scorpion with "dual thread" type barrel with our 6.84" angle handguard installed? The barrel probably has two types of threads; M18x1 for the barrel nut, stepping down to a 1/2-28 thread at the muzzle. The larger M18x1 threads are used by the factory barrel nut to retain the factory handguard and flash hider. Under the factory flash hider should be a thread protector on the smaller 1/2-28 threads. The gun is safe to shoot as long as the bore/muzzle is clear; that could be a muzzle device correctly installed on the smaller more common 1/2-28 threads (tight, torqued against the shoulder of the larger M18x1 threads). Or it could be the factory flash hider torqued on the M18x1 threads. The M18x1 threads are long, to the point where they are going to be visible from the top while using our 6.84" angle handguard. What we typically recommend, if the cosmetics of visually seeing the threads is distracting or unsightly, would be to run our 6.84" flat handguard (b/c is extends to cover those threads from the top side). Please don't hesitate to call/email us directly for help or if you want to swap out the handguard shroud to another type/style. We got you 👊
Correct. And a lot of people do exactly this. But if going this route we recommend putting a thin film of high temperature grease/anti-seize (think automotive brakes) on the 1/2-28 threads. Yes, over LONG periods of time it will come off with regular cleaning, but generally a very thin film does a great job of protecting the 1/2-28 threads... the carbon build up will wipe off easily if you ever decide to use the 1/2-28 threads for something else in the future.
Thanks for the tip on using thread lock on the thread protector! I pick up mine this week and would probably have not checked that! Do you recommend the blue threadlocker?
Yes, blue loctite is great for the thread protector. We like the blue 243 for muzzle devices because it seems to resist solvents (ie barrel cleaning chemicals) a little better than the 242 flavor. But... degreasing the threads and applying a couple drops of ANY type of thread lock is far better than running it without.
I got a fan port compensator (meaning 2nd one in your video) and when installing I can't get it to screw tight and have the holes facing upward completely evenly. Always slightly lop sided. You said they must be timed and facing upward but screwed it on and off without showing it completely installed so I have no point of reference to know if it being a little uneven is a problem. I hope someone understands what I mean, it's a little hard to explain
I think I understand what you are asking/what the issue could be. Our fan port comps include a crush washer, and it is important that this crush washer be used with this particular compensator. The crush washer will allow the compensator to be "timed" while in its last rotation. You DO NOT torque the crush washer flat, rather, after the compensator comes into contact with it, simply continue to turn/rotate the compensator until it is in the correct orientation. The deflection in the crush washer is designed to keep the compensator in place. If that makes sense? And if you have "flattened" out your crush washer, please just call or email us, we can send you another :-)
@@hb_industries i have the same issue like A.H. comment. After i put the crush washer and turn/hand tight the compensator the holes ended up at 2 o'clock. Is it safe for the barrel to keep tighten the compensator that much (almost 315 degree-turn)?
@@POGIAKO62 Yes, the crush washers are designed with enough deflection in the taper (crush) to compensate for 360 degrees of mis-alignment on a 1/2-28 thread pattern. Or, one full turn from the time that the muzzle device and crush washer come into contact with the shoulder of the barrel. 315 degrees is a lot, but the washers are designed to absorb it.
I'm planning on getting the tri lug adapter for my scorpion from you guys, the 1/2-28 one. I do not have the m18x1 ring though, the thread protector. Would I still be able to just install the 1/2 28 TRI lug adapter on the end and suppressor without the m18x1 ring?
Yes, you can install a 1/2-28 tri lug directly onto your muzzle threads, it will mate against the shoulder where the 1/2-28 threads step up to M18x1. As you mentioned their may be a gap on the M18x1 threads between that shoulder and the barrel nut, but it will be primarily cosmetic. Not having the M18x1 ring installed will not affect the tri lug alignment or operation.
Thank you so much. I love my Scorpion and I love my other CZ products BUT the Scorpion manual has to be the worst owner's manual in modern firearms history! I'm gonna find something to order from y'all (you have good looking stuff anyway) just to say thanks again.
Nice video. Informative. Thanks. I’ve got a Thompson SG2 with a Gemtech 2 on the way. Any advice on how to attach? Preferably with the tri lug? Thanks again.
3-lug/tri-lug is definitely a very versatile way to mount 9mm/300blk cans. If "Gemtech 2" is their "Aurora-2" model 3-lug would not be an option, and the small lightweight wipe style cans in general not a good candidate for SMG type hosts. (However your Thompson SG2 would be perfect)
The threads on factory CZ barrels are nitrided, which does a pretty good job in our experience at preventing rust on steel (ie: same finish as the outside surface of the barrel). The primary purpose of the thread protector on the CZ Evo is to prevent physical damage to the 1/2-28 threads due to corrosion from heat/burning powder/copper/lead/carbon etc...
I notice the spring tab on the Evo in this video is at a different position than mine is on my Evo. The spring tab is at about 10 or 11 o'clock, whereas mine is just under 6 o'clock (facing the barrel, as if the muzzle were a clock). I haven't messed with installing any kind of muzzle device, why would mine be in a different position?
Great question! That spring tab is secured to the "barrel nut". The reason for the different position/clocking is that the "barrel nut" is not timed to the barrel/handguard/receiver. When the factory installs the "barrel nut" they do not care where in its rotation it meets torque. The nut is simply tightened, and they stop when it meets torque. The final position/rotation of the "barrel nut" will be slightly different on every Evo, and therefore the spring tab position slightly different as well. If that makes sense? It is a very clever design, intended to tie everything together without the need for exact rotational alignment of handguard+barrel+muzzle device.
It depends; you cannot remove the barrel nut if you are using a handguard that requires it (barrel nut retains factory handguard on some models) but if you are running a "free-float" type handguard then yes, you can definitely remove the barrel nut and run a comp that sleeves the barrel or similar.
If "that whole part" is the barrel nut, then it would depend on handguard... The OEM handguard is retained by the barrel nut; therefore if the barrel nut is removed, the handguard is not retained (will fall off). If you are using an aftermarket/free float handguard (like ours) you can remove the barrel nut entirely. Hope this helps?
The Evo S2 Micro models with flash can are a 1/2-28 RH threaded barrel. Removal and installation of muzzle devices on these models is very similar to an AR rifle, no spring tab like the Evo S1 pistols, just left loose/right tight and use a crush washer or rockset/thread lock.
I just got my Fan port Compensator. Can you make a video timing the install of the Fan port on the CZ Scorpion, or does it matter if there’s a little imbalance on the side openings?
Did you use the included crush washer? The ports should be symmetric, running from about 9:00-3:00. There is about 180-270 degrees of rotation available in the crush washer.
Great question, answer is "No". Our Ultra Comp for the Evo covers the exposed M18x1 threads, and utilizes the spring tab to lock. If you use the spacer, our Ultra Comp would not engage the spring tab, and could not lock into place. Please DO NOT use the spacer with our Ultra Comp.
The bolt is a huge, heavy chunk of steel slamming back and forth. Nothing you can do about it except go with a delayed blowback system like the CMMG. That usually elimates vibration and recoil.
Does anyone know where I can buy a m18×1 thread protector? Like a replacement factory one. I bought mine used and it didnt come with one. Any help would be appreciated
