The Faxon 9310 Complete Bolt is made using 9310 tool steel that is then given a nitride finish to increase surface hardness, decrease resistance, and have superior corrosion resistance compared to normal phosphated bolts. The Faxon 9310 Bolt is fully MPI tested to ensure the material is sound and without defects. Bolt lugs are chamfered at 45 degrees to ensure reliable action for even the highest pressure hand loads. The extractor is made from S7 Tool Steel. From there, the extractor is sprung using the spring, o-ring, and silicone insert.
