Walker Defense Research FDE DLC Bolt Carrier Group (BCG)

The Walker Defense Research M16-profile FDE Bolt Carrier Group BCG features a carrier and gas key finished with IonBond’s Flat Dark Earth DLC (diamond like carbon) coating. FDE DLC offers lower friction, and easier cleaning, and better lubricity (including a lower overall need for lubrication) compared to a standard mil-spec manganese phosphate Bolt Carrier Group BCG. The bolt itself features black DLC and is MPI (Magnetic Particle Inspected).
