I have a stainless awc psr muzzle brake for sale. Brand new never mounted. Thread protector included makes designed to be paired with the awc psr can. Or used stand alone other suppressors will fit as well as long as the thread pitch is the same and the inside diameter clears. Bought this for a build a couple of years ago went a different direction and it's been sitting in my war room. 150 tyd with tracking. Only trades I'd be interested in are a kifaru para tarp or super tarp with cash on my end. https://surgeonrifles.com/shop/awc-psr-muzzle-brake/ link to surgeons site with more specs. I believe mines a 5/8-24 pitch but not 100 % I can be reached here by pm or call/txt 209-556-3434 Sent from NSA wire tapped device.
