Thread on cans

[motoduck]

I prefer cans with a quick, dedicated and locking mount. But, I own several thread on cans. The issue I have is that on some of my rifles the threaded cans like to work loose after only a couple of shots. It's not a big deal on the range but in any dynamic enviroment it becomes a problem.

Does anyone have a simple fix they use to help solve this common isssue?

I like using a simple wedge lock washer. If the shoulders are true on the barrel and suppressor, you will not have any alignment problems.

Teflon tape is a good temporary fix, but it will eventually work loose as well. It will just stay tight longer and it helps protect the threads.

I use a couple drops of blue loctite. After a shooting sessin most of it burns off so the can is easilly removed but just enough remains to prevent the can from loostening while shooting.

Very bad idea. NEVER use a washer.

This guy has it right. A few layers of Teflon tape will do the job nicely.

Most of it burns off? Loctite is for fasteners, not suppressors.

Actually the washer I mentioned works very well with a can, provided that the shoulders are true, as I stated. I have used them for many years and provided them to lot's of customers who have never had a problem. A regular lock washer is of course a disaster waiting to happen.

I don't think you will find one suppressor manufacturer who will condone the use of any type of washer let alone a two piece lock washer with an inside tolerance of .500 to .749.
