Faxon AR-15 Bolt Assembly 6.5 Grendel, 6mm ARC, 22 ARC, 338 ARC

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
