Polished Nitride 5.56 BCG




If you know what these are, then you know these things absolutely fuck. These BCGs have the NICEST, SMOOTHEST nitride finish on any BCG I’ve handled in a long time. the Bolt moves like butter in the carrier and the firing pin also has a beautiful shine on it. I’m getting a solid deal on a bulk order so hop in and join the order.

Our Nitrided M16 BCG is micro polished before and after the Melonite process, producing a beautiful finish and an extremely slick surface. The carrier is made from 8620 steel. The bolt is made from 9310 steel and is MPI Tested and engraved. The 223 Bolt and Bolt Carrier Assembly is compatible with 5.56 and 300 Blackout.
