Faxon AR-15 Bolt Carrier Group 6.8 SPC / 224 Valkyrie Nitride

Faxon Bolt Assembly improvements include using 9310 tool steel for the bolt, nitriding the assembly to increase surface hardness, decrease resistance, and 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. Extractors are S7 Tool Steel. From there, the extractor is sprung using the spring, o-ring, and silicone insert.
