So now that i have two thread on cans on the way, I have a plethora of people telling me that i should have gotten a brake attach method so they wont start to come off after a few rounds.

I emailed the manufacturers and they have a washer kit for the .223's but not for the .30 cal ones. Is this a large concern or can i put a bit of Teflon tape on the threads to keep them locked? I don't plan on doing magazine dumps, but i do want to avoid a baffle strike.

On my 9mm & .22lr cans I just always check it every other mags or so. On my M10/45 I check it EVERY mag.

All 6 of my form 1 cans stay on very tight and never even slightly come lose
They are all thread on cans so it's hard for me to understand what the silencer manufactures are doing wrong

Any special kind, or just the cheap stuff from Lowes?

Most likely if the person that built the can, prepped the barrel as well, it would be a none issue. Bulk, Factory threaded barrels, are lacking most of the time.

Usually the problem is preventing them from seizing.

Suppressors are threaded to have a little slop so they will thread onto anyones barrel threading. Not all threads are created equal. A good smith can cut your barrel to match you suppressors threading. That's how I do my builds

I run the can down until it shoulders, back it off a bit, then give it a quick twist to seat.
 
Re: Tips on keeping suppressors tight

I've never had a single problem with a can backing off. Including some range trips that number into several hundred rounds. Not a single time has my thread on can backed off.

IMHO, I wouldn't mess with it unless you are actually experiencing problems with it backing off.
 
Re: Tips on keeping suppressors tight

We (HTG Silencers) thread our cans to class III tolerances. This means they are in spec but on the tighter end of the specification range. This helps with alignment and keeping in place. If your barrel is threaded with a decent job, it shouldn't be much of an issue.

Use some teflon tape or paste if the cans back off. Just check them frequently at first to make sure everything is staying where you want it.

Also, you will find that thread on cans are typically more accurate than the ones with the QD systems. I don't think you have anything to worry about with your direct thread cans.

Enjoy shooting suppressed.
