The Faxon Firearms Type 2 Bolt Carrier Group (brand part no. FF65GBCGCNITRIDE) is built for the 6.5 Grendel, 6mm ARC, and 22 ARC cartridges, using a 9310 tool steel bolt that is salt bath nitrided for surface hardness, reduced friction, and corrosion resistance beyond typical chrome or phosphate finishes. Faxon Firearms chamfers the bolt lugs 45 degrees for reliable lockup even under high-pressure handloads and fast-cycling lightweight actions, then super-finishes the whole assembly to cut friction and fouling. Every bolt is magnetic particle inspected for soundness, and the group is full-auto rated to maintain the trip for full-auto fire control groups and modern multi-stage triggers alike.
