Are you running a .30 rifle can on it?
I've stayed away from .300 for several reasons. Shooting subs, it's ballistically .45acp, and I have SBRs for that, and I don't want to have to buy another caliber. I'm curious how it works out for you, and how it shoots. I've considered doing a .300, I just can't convince myself I need it.
Yessir, stainless 30 cal SAS suppressor. I can't tell you why I built it, I honestly have no idea lol.
