Faxon Gunner BCG Ultra-Light Bolt Carrier Groups

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. We set specifications that would allow no compromise:1.     Lightest Weight Possible (8.32 Ounces Complete, 6.24 Ounces Carrier & Key Only)2.     MIL-SPEC Materials & Finishes or Better!3.     Forward Assist Serrations4.     Compatible with Dust Covers5.     Maintains Full-Auto Trip Sear for full-auto and the new multi-stage trigger functionality6.     Looks AmazingMatching 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. As a testament of our trust, the carriers are all laser-engraved with the Faxon Shield after passing all Quality inspections.Detailed Spec:Bolt:9310 Tool Steel Construction (Stronger than C158)Full MIL-SPEC Heat TreatmentShot Peened to MIL-SPECMagnetic Particle Inspection (MPI)Back of Lugs Chamfered for ReliabilitySpring, Insert, & "Crane" O-Ring InstalledQPQ - Salt Bath NitridedExtractor:S7 Tool Steel ConstructionFully Heat TreatedShot Peened Per MIL-SPECQPQ - Salt Bath NitridedCarrier & Key:Carrier: MIL-SPEC 8620 Steel MaterialKey: 4140 Steel MaterialFully Heat TreatedForward Assist SerrationsM16 (FULL-AUTO) CompatibleGrade 8 FastenersFully & Properly Staked Key, Permatex SealedQPQ - Salt Bath NitridedWeight w/ Key (Not Bolt or any Pins): 6.32 OuncesCam Pin: 4140 Pre-Hardended Steel MaterialQPQ - Salt Bath Nitrided
