The FosTech Complete Bolt Carrier Group (brand part no. 6228) is a full AR-15 bolt carrier group finished in a nickel boron coating, built as a drop-in replacement for a standard BCG. FosTech Outdoors applies the nickel boron finish for a smoother, lower-friction cycling action that also resists fouling and wipes clean faster than a standard phosphate finish.
