Faxon AR15/M16 (5.56 NATO) Replacement Bolt (Black Nitride)

Seeing "MIL-SPEC" as just the starting point, we set out to ensure the best options are available for our demanding customers. Improvements include using 9310 tool steel for the bolt, nitriding the assembly to increase surface hardness, decrease resistance, and have superior corrosion resistance compared to typical phosphated bolts. 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.
