I've got three suppressors, two .22 caliber, one centerfire. There are a couple of problems with center/rim interchangability. First is the diameter of the threading; my centerfire suppressor has a larger thread than my .22s. Getting the all-purpose suppressor hasn't been my experience. And a rimfire suppressor (which will fit an AR flash hider) won't adequately suppress a 5.56.
Second is that a large suppressor (centerfire) will often block iron sights. Can't see them with that big can on the end. This is the case with a pistol of mine, even with a .22 suppressor...it's quiet, but I can't see the front sight. No problem with a scoped rifle.
My best suppressor is the 10-22 with the full barrel suppressor. Looks like a heavy barrel 10-22 and is pretty quiet.
