Seeing "MIL-SPEC" as just the starting point, we set out to ensure the best options are available for our demanding customers.
Improvements include using 9310 tool steel for the bolt, 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.

  • 9310 Tool Steel Bolt
  • Full MIL-SPEC Heat Treatment
  • Shot Peened to MIL-SPEC

    Currently own 3 of these BGCs paired with Faxon Barrels. The fit and finish is second to none. Coating is super smooth and durable. Will continue purchasing from Faxon.

    Best BCG I’ve ever had!

    Posted by Kevin on Feb 21st 2022

    If you are looking for an amazing BCG look no further. I’m a gunsmith in Colorado. This is by far the best BCG I’ve ordered. Not only does it look great it cleans up amazing and runs very smooth. I’ve matched this BCG with binaries and mil spec triggers and it runs. Lost count of how many rounds I ran through at the last range but it ejected and ran very well. Definitely gonna get more of them and recommend them highly!
