When looking at lightweight bolt carrier groups, we were unsatisfied with what the market had to offer. Seeing a capability gap, we set out to create a bolt carrier group that could live up to the GUNNER name with no compromise in strength or function. Faxon recommends the use of an adjustable gas block with our Gunner lightweight BCG for proper function.
Matching our barrels, we 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. Faxon recommends the use of an adjustable gas block with our Gunner lightweight BCG for proper function.
