Liberty Cans Cosmic Suppressor

IMG_1077

I got my hands on a Cosmic X Liberty suppressor from Silencer Shop to try out on my Glock 41 and Glock 21. I am using a Lone Wolf threaded barrel for my Glock 41 and Glock 21. As you can see from the photo above, the Cosmic is rather long. It is longer than my Glock 41 slide and longer than my KRISS Vector extended magazine; if you do not include the 3D printed speed plate. Although the Cosmic is long, it is rather light weight. It is made of Stainless steel and titanium and only weighs 9.5 oz. Of course shooting 230 gr .45acp is as expected. . . quiet.  I wanted to see what a monocore suppressor was like. I did not notice much difference other than the size of the can compared to a SilencerCo Osprey. The Osprey is 8.06″ long while the Cosmic suppressor module alone is 8″. With the direct thread nielsen device mount, the Cosmic measures 9.5″. With the tri-lug mount, the Cosmic measures 9,25″.

With the size of the Cosmic and my KRISS Vector extended magazine, the SureFire X300U looks a bit minuscule. So on the advisement of a friend online, I supersized the weapon light to match the oversized scale of this setup and went with my SureFire M111D with KX9 LED head.

I was able to mount the Cosmic monocore to my  CZ Scorpion EVO3 with the help of a Manticore tri-lug adapter and Liberty’s tri-lug mount.IMG_1089 IMG_1092 IMG_1098

Cosmic can on Zenith MKE Z-5RS.

There is an issue when using the tri-lug mount from Liberty. It was a bit too tight for my Zenith Firearms  MKE Z-5RS and Manticore tri-lug adapter. I spoke with Sven of Manticore arms and he assured me his tri-lug adapters are to H&K specification. The Zenith MKE MP5 is made from H&K tooling so it should also be in the same specs with regards to the tri-lug. However there was still an issue with the Liberty tri-lug mount. First of all it physically would not fit on the Manticore Arms tri-lug adapter. The tip of the adapter was just too wide for the Liberty mount. By a couple thousandths of an inch. Under Sven’s recommendation, my friend Brian helped me chuck the adapter into his lathe and we used emery cloth to reduce the OD of the adapter tip.  The tri-lug mount would fit on the MKE Z-5RS but after shooting a magazine worth of ammo, the suppressor did not want to come off the Z-5RS. No it wasn’t heat expansion or carbon build up. There is a sleeve inside the tri-lug mount and the tolerance of that sleeve is just too small. I can feel it doesn’t sleeve over the Z-5RS as smoothly as my modified Manticore adapter. The suppressor did come off with brute strength but it was difficult. It was rather annoying.

Other than that issue, the can is a lot of fun. It does very well with the intended caliber, .45acp. With 9mm it did surprisingly well with 135gr  sub sonic loads and 124gr NATO ZQI ammo. 115gr were hearing safe but I could hear the echo of sonic boom in the valley we were shooting in.

Here is a list of approved calibers that can be run through the Cosmic.

454 Casull
45 Long Colt
45 ACP
45 GAP
44 Remington MAG
44 Special
41 Remington MAG
41 Action Express
40 S&W
10mm Magnum
10mm Auto
.400 corbon
458 SOCOM-NOT RECOMMENDED TO BE HEARING SAFE. BUT THE SILENCER WILL HANDLE IT.
450 Bushmaster-NOT RECOMMENDED TO BE HEARING SAFE. BUT THE SILENCER WILL HANDLE IT.

 

They do not list 9mm, .300blk sub sonic or other calibers. We can tell from the video above that it does a decent job for 9mm. Time will tell when I get a 9mm specific can and test my Scorpion, Z-5RS and some other 9mm carbines. I got a Tavor coming in to test and will be suppressing it.

    Sounds like a dedicated 9mm suppressor would be more quiet for 9mm then.

    • JSmath

      Always a given with any suppressor. The tightest caliber fit it can get, the better it’ll reduce the blast. Shooting 9mm (.35 cal) out of a .45ACP has a slight hotdog-in-hallway effect to it.

      Because technically you CAN use a .50BMG suppressor to shoot 9mm, but that doesn’t mean you should or that it’ll be as effective as you would think it should be.

      • In these caes, I’ve heard of ppl placing a sorbothane gasket on the end to help seal things a bit more. Works for at least a dozens rounds.

        • thedonn007

          I hope that is not considered a baffle.

          • jimmie mason

            It’s a wipe which is replaceable.

          • The interesting thing about the Ghost-M is what the Dead Air folks have done to reduce the problem of first-round “pop.” With most suppressors, the initial shot will be louder than subsequent shots because the can interior is cool and the difference in temperature creates more noise when super-hot gas blows through the comparatively cool silencer. The Ghost-M has a spot for a rubber gasket with a small hole in the center. This goes right behind the front cap so the bullet passes through it before exiting. The gasket serves to chill out the gas blast and dramatically reduce the first-round pop. The gaskets are disposable and good for 30 to 50 shots before they start to lose effectiveness. You can leave it in there much longer, it just won’t work quite as well.

            Note the gasket in the end cap. That helps reduce the first round pop noise.

    That customized milled M-LOK compatible handguard on the Scorp is still awesome!
    It should come like that from the factory.

    The nicely used 41 is a handsome looking gun too!

    • Nicholas C

      Thanks. John Saunders of NYC CNC did the milling for me. It is WAY better like this. Although I have no basis for this, CZ USA’s new carbine Scorpion has a new MLOK

      handguard and I like to think that my Scorpion may have influenced that decision.

  • JSmath

    Nicholas, sir,
    I humbly request you get some .40SW 135/165/180 time on the can, if you can.

    Been pretty sure that I want to make the Cosmic my next suppressor, just not entirely sure I want the ~10″ length for all the compatibility in a two dozen cartridges I’ll probably never own or use.

    • Nicholas C

      I would but alas I do not have any threaded barrels chambered in .40 s&w. I have a .40-9 conversion barrel from Lone Wolf for my G35.

      • Nicks87

        Nicholas, what barrel do you have on your 41? I noticed it kind of sticks out of the slide quite a bit.

        • Nicholas C

          Glock 41 or 21? In the Video you can see my Glock 21 (black frame). Well anywany both of them are threaded barrels by Lone Wolf. I bought the long barrel for my Glock 21 because it was on sale. When i got the Glock 41, I thought “PERFECT! I can use this long barrel” Nope. 41 barrels have a narrower OD than 21.

          • Nicks87

            I’m looking for a threaded barrel for my 41 but I want the threads to be fairly close to the slide so when I mount a can it looks flush. It’s good to know that G21 barrels wont work with the G41 saves me some hassle.

      • JSmath

        Why you no have friends with 40? 😐

  • Don Ward

    Reading this on my small mobile screen I thought “Why would someone attach a flashlight to a rafter square?” Then is saw that there was a Glock mixed up in that contraption.

    • Nicholas C

      It isnt really a contraption. It is a Glock with a suppressor, light and extended mag. Nothing out of the ordinary

      • rjackparis

        ..

      • Bill

        Yeah, it’s out of the ordinary, sort of like a MK23 with a LAMS and can is out of the ordinary.

      • Giolli Joker

        Does the suppressor blow back hot gasses below the Glock’s muzzle?
        What is the reason of the discoloration there?

  • thedonn007

    Could you run some .300 blk or .450 Bushmaster through it as well?

    • Nicholas C

      I think you could. But don’t take my word for it. Ask Liberty Cans. My reasoning is that the SilencerCo Osprey can handle sub sonic .300blk. So I dont see why the Cosmic couldn’t handle sub sonic .300blk either.

      according to their website it can handle .450 bushmaster but not hearing safe.

      • Anonymoose

        Assuming you built up subsonic loads in the .458 SOCOM and .450 Bushmaster, would it be hearing safe then? What about a mellow .45-70?

      • Cymond

        No reason to ‘think’ it can. Liberty explicitly states the Cosmic can handle 458 SOCOM and 450 Bushmaster. http://libertycans.net/cosmic/

        Also, the Cosmic can shoot all of the calibers of the Mystic-X, which includes 300 Blackout supersonic from an 8″ minimum barrel length, and full-auto 300 Blackout subsonic from a minimum 8″ barrel length.

  • Malthrak

    I read “Liberty Cans Cosmic Suppressor” as “Liberty Comic Sans Suppressor”…and was really confused for a second.

    I’m very happy I read that wrong.

    • Nicholas C

      LOL that is pretty good.

    • avconsumer2

      lol – there’s an April Fool’s joke in there somewhere.

  • Mike N.

    Mine is still in NFA jail.

    The list of approved calibers above is in addition to what is approved for the Liberty Mystic X, the 9mm version of this can. So also .22lr, 9mm, 300 blk, and .223 (within limits).

    • Nicholas C

      I am not sure how well .223 will work since the opening at the end of the can is so large.

  • avconsumer2

    Bonus: I’m fairly certain that if you ran out of ammo on that extended magazine, upon throwing the entire rig just so… it’d come right back. (may require practice)

    • M C

      The Australian government will no doubt announce a ban on tactical boomerangs shortly.

  • El Duderino

    Why in world would they bother listing .41AE? It’s been dead for what, 20 years? Why not list .38 Casull and .40 Super too?

  • Greg Anderson

    I was sleepy enough to read that as “Liberty Comic Sans Suppressor”

    • El Duderino

      It will eliminate all noise and blast from poorly-worded corkboard announcements by the office manager. Tier 1 approved.

  • M C

    Did anyone else see that first picture and immediately think of autoweapons.com ?

  • Salty

    You try shooting with the mono core on to see how well of a muzzle brake it is?
