Title: Evo 3 S2 faux suppressor issue
Post by: M012617 on March 13, 2019, 09:33:16 AM
So after my first 100 rounds through the Evo 3 S2 (worked flawlessly btw) I noticed that the faux suppressor had come loose. It was slightly wobbly and would rattle a bit when shaken. I was able to tighten the nut at the front end of the fake can with an AR tool and that solved the issue for now. Curiously though I could not unscrew it completely. It seemed to become tighter no matter which way I turned it. Anyhow I emailed CZ about the issue and will post response. Not sure if anyone else has had a similar issue. (https://uploads.tapatalk-cdn.com/20190313/b3d5da2c66e7fbfc437b0fd78d1d384b.jpg)(https://uploads.tapatalk-cdn.com/20190313/2b3ec76610b58379cbe2d869b805d032.jpg)

In other news, the faux suppressor seems to really help with shielding the heat from the barrel. The handguard never felt warm to the touch despite rapid fire.(https://uploads.tapatalk-cdn.com/20190313/f6961fe27e98bcd69859dcb48bea719c.jpg)

I really like that faux supressor look. That's my next machining project for my Scorpion. I assume that's the CZ micro....

I took my handguard nut off and felt tighter as it was being taken off from the thread lock they use.

I believe that faux osprey suppressor is a  removable shroud. If you end up suppressing it then it can come off for the real deal.

Yup and it does a great job of dissipating heat. However, I found it unsettling that it came loose after only 100 rounds.

Response from CZ, "For the Scorpion Micro there is a castle nut that tightens and secures the faux suppressor onto the muzzle threads. There is a special tool that tightens this castle nut so we would recommend that you send the firearm in to us. However if you would like to have the tool yourself, you may be able to contact SilencerCo to see if they have any available for sale."

I reached out to silencer co but am wondering if anyone has any suggestions for a tool I can use.

Also, the castle nut loosened again during my second range trip.

Does the castle stick up past the suppressor or does the tool have to be inserted? It's hard to tell from the photos.
Would something like an adjustable spanner wrench work or something like the

Looks like a spanner could be made from an air impact socket with the appropriate outside diameter or even a piece of heavy walled pipe with a rod attached through the outer edges and then notching it to make the teeth to fit the nut's notches.

That's probably the best option for a recessed nut. They have spanner sockets for $6-10 that should work. Probably $45 cheaper without the sico name. Get some high temp lock tight and re-tighten.
This is also an issue when using a direct thread suppressor which is why people opt for 3 lug or taper.

Response from Silencer Co

"I am sorry, we exclusively make those faux suppressors for CZ, so we do not make a tool for them. I would recommend going through CZ to get this resolved."

So yeah, I'm going the spanner socket route.

I just got my CZ Scorpion Micro about a week or so ago and have noticed that my faux suppressor has loosened up a little also. Mine hasn't gotten to the point where it rattles, but if you look at the end of the barrel it is obviously crooked in the hand guard opening.  I managed to straighten the faux suppressor with my hand, but after the second trip to the range it's crooked again.

I measured the castle nut and found it to be just over 3/4" diameter. I think I am going to purchase what they call a drag link socket to use to tighten it. You can find them made by various tool makers, but one of the easiest places is Amazon. They list several, but the one in the link below I think will fit the bill.

The tool is probably a smart investment to make anyway because I'm sure that it would be wise to periodically remove the faux suppressor so that the barrel can be cleaned and oiled. Evidently this is going to be an ongoing problem with this suppressor wanna be. I'm thinking about adding a little blue loctite to the threads to prevent it from loosening again.

Did you order the Drag Link socket? If so, curious if it is a perfect fit.

Also, what about high-temp red loctite? I've used that on faux suppressors in the past that I didn't want coming off. When you want to get it off, a little direct heat from a micro torch and it should come right off.

Mine just came in. If it was a hair thicker and just slighty longer it would be a perfect fit but it works as is. I haven't tried loctite yet, I'd rather run it without it. Now that I have the tool and it is tightened as much as possible I hope it wont keep coming loose. If it does, I'll go the loctite route.

Thanks! Looks like that will work fine. It also might work to get a wider one as it will be thicker and then notch it so the width will fit. But I suppose if that one doesn't mark up the nut, it won't matter.

Thanks for sharing, have been trying to find a way to remove the faux suppressor so I can replace it with a kaw valley linear compensator. I have one on my mpx and it makes it sound like a .22.

Glad to see the drag link socket worked. Probably a better tool would be a 12 Ga. shotgun choke tube.  A 12 Ga. shotgun has a .73" bore, so a shotgun choke tube removal tool should work.

There are so many different styles of choke tube tools out there that it would probably be hard to find one that fits perfectly without being able to check it out in person, but it looks like the one in the link below would work. It has six lugs on it, so it should do a better job than the drag link socket and also have more gripping area. By having 6 six lugs on it, it should fit more securely and would probably prevent any accidental slippage.

I would imagine that anyone who takes their faux suppressor off frequently might find something like this a better choice.

Note that the splines on the choke tube tool in the picture are tapered. They will need to be straight splines for the castle nut on the CZ. This doesn't mean that it is not the right idea, just that that socket would not be a good fit even if the right size was found.

I tore mine down tonight, removing the Faux Suppressor "nut"  slowly using a pair of horseshoe clip pliers.  Since it was already loose it came off.  I wanted to take the "nut" out to look for some sort of tool with out bringing the whole gun.  I was hoping to find some sort of spanner socket or castle nut socket or something.  I tried auto parts stores, Bass Pro and Home depot lastly.  I was about to give up when I spotted a universal tool that normally I would not give a second thought to.  It was less than 10 bucks and being retired Navy, I get a discount so I tried it.  It's called a Gator Grip.  If you hold it on the nut square, it will work.  I wouldn't torque to hard though.  Until the correct tool is available, I'll use this.  Here are some photos of the Faux Suppressor removed.  I'd call it more of a barrel shroud.

It certainly seems like finding a tool that fits this is becoming harder than it should.

I contacted CZ-USA asking them to ask their gunsmiths what tool they recommend and if they can either sell one or give a parts number so that I could order one somewhere. They responded that they don't have a tool for that, but told me to contact SilencerCo.  According to CZ, SilencerCo makes these for CZ and they should have a tool. That answer seems strange because from my understanding, the CZ Micro comes to CZ-USA in basically a kit form. CZ-USA installs the after market parts like the faux suppressor and the HBI hand guard and then sells the completed Micro to their distributors. In order to install the faux suppressor, they must have a tool. Evidently CZ-USA customer service doesn't know where to check for this.

Multiple attempts to contact SilencerCo have failed. They have not answered multiple emails. So I guess the search continues.

For those of you that tightened the castle nut, did you tighten it any particular amount? And did anyone end up using loctite? Took mine shooting for the first time and got the twist, maybe like 3 or 4 degrees to the left as you stare down the barrel. 100 rounds.

Ordered one of the things that was mentioned in this thread for just in case, gets delivered today.

After shooting mine for the  first time today I think the faux suppressor is slightly canted but just ever so slightly. I had ordered the tool just in case and it?ll be here this week. But, it?s possible mine was slightly canted when new because if it came loose today while shooting, I?d expect to be able to rotate it a bit, but it?s 100% not movable, it?s firm in place. Is there a set screw holding it in place or just the tension of the castle nut? I don?t want to force it back to straight by hand only to find I sheared off a set screw I didn?t realize was inside the handguard.

It?s probably like maybe 1-2 degrees off perfect. I?m thinking I should leave it alone and only deal with it if it gets worse?

Post by: M012617 on June 11, 2019, 07:24:20 PM
It's just the castlenut holding it. Mine keeps coming loose even after tightening it. I'm going to be applying loctite and see what happens, though I'm not sure itll be all that effective.

Ok thanks. It?s odd though how if mine did come slightly loose today, why does it feel 100% not loose? I can?t twist it to save my life, and I?m fairly strong. [emoji2371] that?s  why I wonder if mine is fully tightened and not loose, just canted slightly even though it?s fully tightened.

Mine continues to turn slightly after firing despite the use of loctite. I might replace with a Barking Spider or something. So annoying because the gun is so sweet otherwise.

Would it be possible to use some sort of spring washer or crush washer between the endcap & barrel or barrel threads to keep it from backing off? I use a thin o-ring on my suppressor between the thread adapter and barrel. Seems to help a lot.

That's a good suggestion. I'm going to try that and see how it goes.

I removed mine today, I thoroughly degreased the barrel threads, the castle screw threads, and areas where the back of the nut gets pulled into the shroud piece while tightening. Added a liberal amount of blue loctite, made sure none got in the muzzle and tightened the thing as tight as it?ll go with a socket wrench and the HB ind. tool. If it comes loose, the only alternative would be red loctite I guess. But the thing is, maybe I?m seeing it wrong, but I think the shroud can in fact move slightly clockwise or counter clockwise even if the castle not  is tightened down, because I think it?s only  friction and not the threads themselves that is keeping it from moving. Not positive but if true, it?s an issue CZ should address.

I think you're right that it's friction holding it in place. It makes sense from when you take it apart. Disappointing in a way because of that movement. A spacer might help, but I'm sure it would damage the noosprey. I think I'm going to just get a compensator or something for mine.

Bought the KAW Valley linear comp. I'll update when it gets here. If it works out, might replace with a Barking Spider. I have one on my .300 pistol and it's sweet.

I just got the “loosening issue”. I took 2 nickels, clamped them together in a vice grip, and ground them into a “T” shape for a wrench. I put a small o-ring on the barrel threads and cranked the nut down. So far so good. Now to get this binary trigger to work 100%...

Noticed today mine did a small rotation as well. Was able to hand tighten back. Hope a fix is in the works seems like it’s an issue brewing. My gun guy is a silencerco dealer and he has the tools but it’s still annoying if you are fixing instead of shooting.

Pisses me off, my one week old 210 round Micro started this crap on the first range trip.

Save yourself some annoyance and just replace it. KAW Valley Linear Comp, Spike's Tactical Barking Spider both fit. I've used both on mine.

Can you post a pic, also is it the 1/2x28 threading? I got mine too the range today finally and put 500 rounds through it and the faux moves back or forth.

It looks amazing either way, which one do you prefer?

I like them both. KAW is super cheap. Barking Spider has a screw on end caps (flash hider and compensator). Helpful I know. [emoji3]

Well I got annoyed enough to take of the handguard. Now I see that there was a flange built into the faux suppressor. It locks up against the barrel housing and there is a small gap that will allow the faux suppressor to slightly rotate but not rotate enough to come into contact with the inside of the handguard. So now I feel no need to replace it and maybe to just shim it. In an earlier thread I saw the faux suppressor come into contact with the inside of the handguard. I think there was something definitely wrong with that one. The only way that would happen is that the faux suppressor is actually over a 1/4 inch loose and past the flange.

On page 2 of this thread Tommydogg’s post with pictures it’s the 5th picture down. You can see the part against the barrel housing. Right by the HBI lettering. If it’s installed correctly the faux suppressor will not rotate enough to contact the inside of handguard.

Unless it gets to that point it’s just an annoying quirk to me

Yes - the HBI faux suppressor tool works.  Had to use it at the range two times yesterday (300 rds).  Last use of the item was last night when I used it to take off the faux suppressor, don't want the thing loosening up and flopping around.  Ordered a Kaw Vally linear comp, should be in tomorrow.  Great price (and they have a miltary/LEO discount).

Bringing back to life an old thread.
After first 100rds my faux suppressor came loose, surprise surprise. I already had the HBI tool on hand so I really cranked the nut down as tight as I felt comfortable. Next outing, put about 250rds downrange and guess what, faux suppressor came loose again. Today I finally removed the handguard so I could see what was going on. Removed the whole faux suppressor assembly , cleaned the threads with SS brushes and Acetone to remove the unrecognizable thread locking compound that was previously used.
While I had it apart I also placed a .008 shim under the "anti-rotate" flange" of the rear faux suppressor plate on top of the HBI Handguard mount, the faux suppressor absolutely cannot rotate around now, which MIGHT BE contributing to the loosening nut issue. 
While examining the barrel threads, found that there is a relief cut between the rear of the threads and the barrel shoulder. Has anyone tried placing a lock washer or wave washer on the shoulder to help lock the faux suppressor nut in place, in addition to Loc-Tite?
At this point I've just applied #271 Red Loc-Tite and reassembled. Am hoping this works because I like the look and really don't want to go the Linear Comp route unless I have to.

Honestly I didn’t put as much thought into this as you have...mine came loose just about every outing, and I kept the tool on-hand to get it roughly finger tight as I was shooting, and would torque it down after cleaning. I liked that it was easily removable, because frankly I only worried about it until my real suppressor got out of NFA jail. That....is the best mod to the Micro I have done hands down.
