Perfect for your next AR-15 rifle build, the RW Arms – Bolt Carrier Group, 5.56 Complete – Black Nitride is a high-quality BCG. Installing this on your rifle will assist and help take your customized rifle to the next level. Machined from 8620 steel, the RW Arms mil-spec bolt carrier group is heat-treated with a black nitride finish so there’s lower friction that minimizes the need for lubricants and cleaning.
