Description

We just can’t help not accepting the status quo. Bolt carrier groups are available aplenty, but few could meet our exacting standards for performance and value. 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, 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.

    It’s good

  2. Kyle (verified owner)

    I’ve had no issues with these bolts. I’ve see some reviews elsewhere claiming problems, but I haven’t experienced a single one. Head spaces great and cleans easily. Excellent

    Matched this BCG to the barrel because I’m borderline OCD and like to keep things uniform. Can honestly say I’ve had zero issues at all with any type of shooting. Solid product.
