Out of stock
MANUFACTURER’S 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.

- 9310 Tool Steel Bolt

Faxon Quality
Love Faxon’s BCG - ran about 500 rounds on one of them yesterday. Solid and consistent performance.
USGreat product and service
Easy user interface. Great product and delivery time. Will be using again.
USExcellent
I went to the range and my oh my, this BCG was BUTTER smooth!
USFirst Quality BCG
I ordered this to go with a Faxon pencil barrel in .556 and a Aero Precision M4E1 upper for a light weight build. I also used a Spikes Tactical melanite coated gas tube. The gas key was a snug fit and needed a tiny bit of oil. The BCG is first quality. The workmanship and attention to detail really show. I would recommend this BCG to anyone.
USBCG
Bolt functions flawlessly, great quality and well made.
