I've had a Gemtech Mossad II since 2017. I have several thousand rounds through it. Works great and just replaces the barrel nut so you dont need an adapter. The downside is, you cant use it on any other guns, and you cant take it apart to clean it. I bought a Liberty Mystic X and a Liberty Cosmic nad am happy with both. You can take them apart to clean and they are multi caliber.

I have the original Mystic and very displeased with how difficult it is to take apart to clean even as low as 1K rounds of FMJ, no lead. The monocore design they use has no shielding to prevent build up between the core and tube. If they did like the Silencerco Sparrow it would have prevented that. I had my Mystic cut down and re-cored to something else.

I agree.
I usually beat one end against a tree stump and then loosen the lock nut and keep beating it. Also, I’ve used a wooden dowel against the blast baffle with a hammer. I’ve hit it so hard that I’ve stripped some threads off the lock nut. Somehow, it still works but it’s kinda pos design.
I’ve tried anti seize on the inside of the tube but doesn’t seem to help much.

I was so pissed off with mine, this is what it looks like now:

Finally I acquired a YHM R9 to which I fitted the 3 lug attachment. I found the length and diameter what I consider to be in the "Goldilocks" range (short, but not too short, not fat and not too thin) and the specs and price on the R9 made it an easy choice. It's by far the easiest to use and best looking can for the UZI, IMO.
...
So TLDR: My recommendation for a UZI suppressor would be the YHM R9
Concur. Love my R9 setup.

I've never been a big monocore fan, but without shielding they can turn into a nightmare. I have had good success painting a healthy coating of Frog Lube paste on the baffles and all interior surfaces of a suppressor. It's largely carnauba wax with some fragrance and a few other ingredients. The first few mags will smoke fairly heavily, however it will maintain a greasy film on the internals that makes it somewhat easier to disassemble and clean suppressors .

I really just hate the use of Aluminum in Suppressors as it really limits cleaning options. The other problem is that Aluminum is more porous than stainless steel ( say 316 or 17-4), so carbon and spall deposition can adhere to Al ( even galvanized) more readily than its counterparts.

+1. I don't like Al in cans either but in some scenarios I have worked around it like below:
The outer tube on the MK9K (and now shortened to be a CT9KS below) is aluminum but with that .005" shim stock, it never needs cleaning now. The front and rear end caps of this one are also aluminum but I can just knock the large chunks off. The core is all stainless steel. I also have an old school MK9K Bixler 3 lug mount that is also all aluminum and it seems OK for that purpose. The Bixler mounts don't get clogged up like thE typical push / turn 3 lug mounts do.

I just got a Cash9k and made this custom SS adapter to use the Gemtech barrel nut and interface with the Alpha thread pattern of the Cash9k.
I was very skeptical that this tiny can would perform as great as the Youtuber's say. Note that all the stellar reviews are using the thread mount. Using their typical push/turn 3 lug mount places the muzzle very close to the blast baffle and I think bypasses the flow through.
The custom SS adapter I made has a bearing surface like the original short Gemtech barrel nut mount that provides additional alignment with the shortened UZI barrel. This also places the muzzle where their direct thread mount would be for best performance.
Not as quiet as my CT9KS or MK9K but being this small and light is truly amazing. It didn't ring my ears and I wouldn't hesitate to run it without hearing protection.
The suppressor module is 5.8oz and 7.5oz with the direct thread mount. I didn't weigh it with my custom UZI mount setup yet.
The tube is Titanium and the baffles are SS and the unit is fully serviceable.

I also made a custom Bixler 3 lug mount for it.

Congratulations on your full auto Uzi purchase! Pairing it with a good suppressor is a great idea to help reduce noise and make shooting more enjoyable.
The Bowers Vers9 is a solid choice, as it's specifically designed for submachine guns like the Uzi and has a good reputation for performance and durability. If you can find one in good condition, it should serve you well.
The Gemtech Mossad II is indeed discontinued, which makes it harder to find and may also present challenges with regards to maintenance and replacement parts.
Other suppressors you might consider for the Uzi include the SilencerCo Omega 9K, the Rugged Obsidian 9, or the Dead Air Wolfman. All of these are highly rated for their performance, durability, and versatility.

I don't have my uzi yet but for what it's worth I'm going Omega 9K with an angstand arms 3 lug flash hider or muzzle brake. I've found the Omega 9K performs extremely well for it's size especially on longer barrelled PCCs like the Uzi is.

Are you getting a full auto UZI? Bear in mind that the Omega 9K is sealed. Yes, you can clean with solvents but you don't have direct access to the baffles to scrape chunks off. Or the ability to just drop the baffle core into an ultrasonic cleaner. You don't get direct agitation to the baffles by just dropping the entire can in an ultrasonic.
I heard the Omega9k and wasn't impressed. If you really want small and light, I would look at the Cash9k as it is even lighter than the Omega9k, I think performs better, fully serviceable and composed of Titanium and SS. Capitol Armory had them in stock 2 days ago for 574 but looks like they went OOS again.

Yes full auto. I own 2 Omega 9k's and no issues with fouling after thousands of rounds so I'm not concerned. If it gets bad I have an ultrasonic cleaner that cleans anything very well with a certain solution. Or just shoot a couple 300 blackout rounds through it to knock everything loose.

I also have a Spectre 9. It is shorter and lighter than the cash9k. The omega 9k is very impressive for it's size in my opinion. Direct blow back guns aren't that quiet anyway because of port noise. I buy many manufacturers, but SiCo is my favorite because they are a large company not at risk of going out of business and their customer service is the best in the biz. I use the Omegas on PCCs and the Spectre on pistols because it is lighter and thinner.

The only can's I've found that really need to be cleaned on a regular basis are 22 cans. Additionally fully sealed, tubeless cans like the 9k are stronger which is a good thing for a machine gun.

Have you run your Omega 9K's in FA 9mm yet? I think it is a different story for FA. Did you weigh the cans new? I would keep an eye on that.
I have a Liberty Constitution that is an all steel monocore and my thoughts were to use it for my belt fed LM7 22LR upper on the M16 and then I could just dump FA 556 to 'knock everything loose'...didn't do anything in my experience.
I am an FFL / SOT, so I gutted and re-cored it.
I hear you on the sealed / tubeless being stronger but I don't think that is needed for 9mm and me personally, I like the option of re-coring in the future which isn't as easy with a tubeless / welded design.
Every rimfire and centerfire pistol caliber can that I use is either service-able or is now service-able or I plan on making them that way after clogging them up over the years.

I used it with a FRT which is essentially the same time. I know cans gain a little weight from carbon, but I haven't noticed anything crazy. Monocores apparently don't react the same way because of their design to knock loose carbon with high pressure rounds. The Omega 9k is a k baffle can. I know it works because I've done it before haha. After firing a few rounds shake the can and you can hear all kind of crap rattling inside and is comes out when you shake the can. Haven't done this on my omega 9k yet, but have done it with other cans.

My buddy has an old Vortex9 which I think is also K baffle got so heavy it would no longer cycle on his Beretta. Ended up jail breaking it on my lathe to get to cleaned out and working again. Good luck with your endeavors.
