Faxon Firearms 5.56 LIGHTWEIGHT 9310 Bolt Carrier Group Complete - Nitride

Faxon Firearms 5.56 LIGHTWEIGHT 9310 Bolt Carrier Group Complete - NitrideWhen 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. We set specifications that would allow no compromise: Lightest Weight Possible (8.5 Ounces Complete, 6.24 Ounces Carrier & Key Only) 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 AmazingTo match our barrels, we selected the QPQ method of Salt Bath Nitride for all carrier 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, reduce resistance, and provide superior corrosion resistance compared to typical chrome- and phosphated bolt carrier groups. All bolts are fully MPI-tested to ensure the material is sound and free of defects. Bolt lugs are chamfered at 45 degrees to ensure reliable action for even the highest-pressure handloads 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 using an adjustable gas block with our Gunner lightweight BCG for proper function.SpecificationsBolt 9310 Tool Steel Construction (Stronger than C158) Full MIL-SPEC Heat Treatment Shot Peened to MIL-SPEC Magnetic Particle Inspection (MPI) Back of Lugs Chamfered for Reliability spring Insert, & "Crane" O-Ring Installed QPQ - Salt Bath NitridedExtractor S7 Tool Steel Construction Fully Heat Treated Shot Peened Per MIL-SPEC QPQ - Salt Bath NitridedCarrier & Key Superfinished Carrier Carrier: MIL-SPEC 8620 Steel Material Key: 4140 Steel Material Fully Heat Treated Forward Assist Serrations M16 (FULL-AUTO) Compatible Grade 8 Fasteners Fully & Properly Staked Key, Permatex Sealed QPQ -Salt Bath Nitrided Weight w/ Key (Not Bolt or any Pins): 6.32 OuncesCam Pin 4140 Pre-Hardened Steel Material QPQ -Salt Bath Nitrided
