The Faxon Firearms Gen2 Bolt Carrier Group is a salt-bath nitride BCG compatible with 6.5 Creedmoor, .308 Winchester, and 8.6 Blackout AR-10-pattern rifles (brand part no. FF308BCGCNITRIDE-02). FAXON FIREARMS superfinishes the bolt and carrier surfaces to reduce friction and fouling, machines the bolt from 9310 tool steel, and MPI (magnetic particle inspection) tests every bolt to confirm the material is sound and defect-free. Bolt lugs are chamfered 45 degrees for reliable function even with high-pressure handloads, and the gas key uses staked grade 8 fasteners for long-term durability. It’s a serious upgrade for an AR-10-platform rifle that needs to run smooth and hold up to hard use.
