Ive heard (and seen vid) from people who use the horrible tac 65 up to the silencerco sparrow ( old version ) and gemtech outback II. they all sounded very nice expect for the tac lol and all complained about the same thing. size matters yes but also the baffle design does as well for blowback and things and I have found that liberty kodiak TL which is 6.5 x 1 has superior design probably due to its length and mono core instead of k baffle and can handle blowback better than the tac which was probably why there was more noise in the bolt chatter.

I was thinking about putting a thick rubber o ring at the end to act as a spacer and buffer and maybe that would help with some extra spring . (modification url removed, can provide through other means) also wanted to ask if 500 shipped was reasonable for an M&P 15-22 MOE dark earth?
