Faxon Firearms Bolt Carrier Group, 308 Winchester, Fits AR-10, Salt Bath Nitride Finish, Black

Seeing MIL-SPEC as just the starting point, they set out to ensure the best options are available for their demanding customers. Improvements include using 9310 tool steel for the bolt, nitriding the assembly to increase surface hardness, decrease resistance, and have superior corrosion resistance compared to typical chrome and phosphated bolt carrier groups. All bolts are fully MPI tested to ensure the material is sound and without defects. Bolt lugs are chamfered 45 degrees to ensure reliable action for even the highest pressure hand loads and fast lightweight actions. • 9310 Tool Steel Construction (Stronger than C158) • Full MIL-SPEC Heat Treatment • Shot Peened to MIL-SPEC • Back of Lugs Chamfered for Reliability • Nested .308 Spec Springs with O-Ring • QPQ - Salt Bath Nitrided • Superfinished Carrier • Fully Heat Treated • Forward Assist Serrations
