Silencer Comes Loose After 15 Rounds Or So...

[The Glockodile]

...it just annoys me to no end.

This is an older AAC Ti - Rant in 9mm, from way before they made the modular ones.

No matter how I tighten it up, it just loosens on its own - everywhere except the end - cap, after a magazine or so of 9mm.



First noticed it midway through this 33 round Glock magazine...



Did 15 and 15, confirmed the issue...



It simply couldn’t stay tight for more than 15 rounds!

It messes up the groups...

Oddly, this wasn’t an issue before...

What recommendations do you have?

Not uncommon for pistol cans with conventional direct thread pistons.

Thread lockers and O-rings are sometimes used successfully, but there are drawbacks.

Griffin Armament has a solution with Cam Lok and EZ Lok. Unfortunately, they don't offer TiRant 9 pistons, but if you decide that's a direction you want to go, we make replacement booster housings for the TiRant that take SilencerCo/Rugged pattern pistons and 1.125-28 Alpha mounts and adapters:



Whatever solution you decide on, take care not to have baffle strikes with a TiRant. The aluminum K baffles perform quite well, but they're also pretty weak, will bend, crack or break off at the waist with even minor strikes. We can recore them with stainless baffles as well, do it frequently, but know that by the time you recore and booster swap a TiRant, you're really just saving a tax stamp & transfer fee vs. buying another can.

Thanks.

Didn’t realize these options existed.

I’ll need to look up the Cam Lok and EZ Lok - don’t know how they work.

Cam Lok is really cool, and is the only QD type option which can be used with "conventional" pistol cans on recoil operated handguns. But it's a little touchy on installation torque and highly susceptible to problems with even slightly out of spec parts, so some folks have had issues. It's the ONLY mounting system I have purchased rather than make in house, because I find it both that desirable and that difficult to manufacture (might be different when my 5 axis mullturn is up & running).

The EZ Lok is basically Cam Lok without the interrupted threads, so still faster and a lot more positive retention than direct thread, just not quite as quick as the ~1/6 revolution installation of Cam Lok but also more forgiving of tolerances and user error.

Downside to both is needing a barrel adapter for each host weapon. Upside is that you never need to change the piston in the can for hosts with different muzzle threads, because the muzzle adapter is the interface. That advantage is huge for people who have a .45 cal can that they swap around on hosts with 1/2-28, M13.5x1LH, 9/16-24, .578-28, M16x1 LH. 9mm pistols are typically either 1/2-28 or 13.5x1 LH here in the states, so not as profound an advantage on 9mm cans, but it's still a lot easier (and cleaner) than changing out pistons.
