Faxon lightweight bolt carrier groups (8.5oz Complete) are prefect for those who want a skeletonized lightweight steel BCG to complement their lightweight AR upper and are looking for a extremely durable BCG with Faxon's Lifetime Guarantee. As a testament of their confidence in the BCG quality, the carriers are all laser-engraved with the Faxon Shield after passing all Quality inspections.

Matching their barrels, they selected 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 Nitride process seals components against corrosion while making them fantastically wear resistant. 

Improvements include using 9310 tool steel for the bolt, 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 have a post-machining Superfinishing process which is a mechancial chemical finish 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 multi-stage trigger systems. Gas keys use grade 8 fasteners and are fully staked for a lifetime of service.

Features and Specifications:

  • 9310 Tool Steel Bolt
  • 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
  • Salt Bath Nitrided Bolt & Carrier
  • S7 Extractor
  • Superfinished Carrier Body
  • Full Auto Compatible
  • Forward Assist Serrations

Faxon recommends the use of an adjustable gas block with the Gunner lightweight BCG for proper function.
