The can is from a company called Mir, I was attracted to its very good price and very light weight.
I definitely am running subsonic (10" 300 Blackout 230gr).
The can doesn't seem to decrease noise at all, in fact it appears to increase noise when fired.
My barrel is DEFINITELY threaded 1/2x28, not sure why the can appears to have mount repeatibility issues from shot to shot.
Any ideas for a fix?
Pictures for reference.
