Faxon Firearms FF65GBCNITRIDE 6.5 Grendel Bolt

The Faxon Bolt Assembly for the AR-15 6.5 Grendel features 9310 tool steel construction, which is stronger than other common bolt materials. The bolt is also nitrided which increases the surface hardness, decreases resistance, and has superior corrosion resistance compared to typical chrome and phosphated bolt carrier groups. The bolt is 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. The extractor is made from S7 tool steel, fully heat treated, shot peened per MIL-SPEC, QPQ nitrided. The Extractor is sprung using the spring, o-ring, and silicone insert.
