I have this in my 5.56 and .300 Blackout ARs they work perfect over 1000 rounds out of each no miss fires and cleaning is always a breeze. Worth every penny spent. Cant wait for the 9mm PCC to become available. Quality work.

I build long range bolt guns and shoot 1000yd benchrest so I know precision. Recently I built a high end ar15. I love this BCG and is the only brand I will ever buy when building them for now on. Easy to clean as well as outstanding performance.

Awesome BCG and looks sexy as hell. I bought a blemish and would highly recommend that for those pushing their budget for a BCG like I was. The imperfection was inside the BCG and would never know it was there without searching for it.
