I am not very fammilliar with supressors, so I have a question for you all.
I have an AR in .223, and an AR in .308. Is there a can out there that I can use on both of these, or will I need to get caliber specific?
Thanks!
The suppressor is very dependent on the diameter of the bullet. You are trying to slow down the gas escaping behind the bullet. If you shot a .223 out of a .308 suppressor, there is enough space around the bullet that there would be very little quieting effect. All the expanding gas (and thus sound) would blow past the bullet and still make noise.
A suppressor will only work with one bullet diameter. It also only really works well with similar "size" rounds. Something setup for a pistol round probably can't contain the power of a same diameter high powered rifle round.
Sorry, but this is NOT true. There is SOME reduction in suppression due to the larger bore in the suppressor. However, there are lots of people who do exactly what the OP is wanting to do and are very happy with the results.
