Im not sure but you can definitly shoot it without hearing protection.Hay Chuck, any idea how much the suppressor reduces the decibels?
Mine is a 30 cal so its a bit louder. I got it for my AK and had to get a left hand thread adapter for my AR. If you a looking a getting one I would recommend building one. It took over a year to get my tax stamp, but it may be shorter now. The form 1 for one you build is much quicker to get approved. You can also build a nice one for a lot less than buying one new.
