Looking for an upgrade to your AR-15 rifle? Check out the POF USA Key-Lock DI 5.56 AR-15 Bolt Carrier Group! This BCG has been designed to reduce friction and wear in the upper receiver, meaning your rifle will be more reliable and have a longer lifespan. The roller cam pin design is NP3 coated and rolls against the receiver instead of the traditional squared off design that rubs against it, while the gas key is dovetailed into the carrier itself and uses a single staked screw. The carrier has an ultra-slick and durable salt bath Nitride finish, and the bolt, extractor, and firing pin are chrome plated for extreme durability.
