    Faxon Firearms set out to create a bolt carrier group that could live up to the GUNNER name with no compromise in strength or function. They set specifications that would allow no compromise: Lightest Weight Possible (8.5 Ounces Complete) MIL-SPEC Materials & Finishes or Better! Forward Assist Serrations Compatible with Dust Covers Maintains Full-Auto Trip Sear for full-auto and the new multi-stage trigger functionality Looks Amazing Matching their barrels, they selected the QPQ method of Salt Bath Nitride for all the carriers’ components. By coating all parts, the carrier's natural slickness is increased markedly requiring less gas and pressure to operate. Further, the QPQ SBN process seals components against corrosion while making them fantastically wear resistant. Improvements include using 9310 tool steel for the bolt, which is stronger and nitriding the assembly to increase surface hardness, decrease resistance, and have superior corrosion resistance compared to typical chrome and phosphasted 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. Faxon Bolt Carrier Groups are Superfinished to reduce friction, increase smoothness of operation, and reduce fouling. Further, they are full-Auto rated and maintain the trip for full-auto fire control groups and new multi-stage trigger systems. Gas keys use grade 8 fasteners and are fully staked for a lifetime of service. As a testament of our confidence, the carriers are all laser-engraved with the Faxon Shield after passing all Quality inspections.
