ATEC Suppressor experience, problems, and troubleshooting thread

[Pommy]

You are supposed to loctite the A-Lock to the barrel to avoid getting it stuck in the suppressor accidentally. And they do say to check the suppressors are still done up tight periodically.

I've not observed a POI shift on any of the rifles I move my ones between. I do put them on in the same orientation each time (based on nothing but superstition).

I have loctited the A-Lock inside of one of them to convert it to direct thread (all the rifles it was being shared between had the same thread anyway). That has tried to come loose on one rifle over the course of a night's shooting (~100rds)... but I suspect any other direct thread suppressor would have done the same.
