  • Product 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.

    1. Excellent choice

      Right out of the box..you can see the beautiful QPQ finish was perfect..not a flaw anywhere. Only gave it 4stars because I'm in the middle of my build. Which I also mated this BCG up with a 16 Gunner..it also was flawless. Can't wait to get my build done and shoot it.Updates will be coming in soon. Stay tuned. on 8th Feb 2017

    2. Best Bang for your buck

      This complete BCG with their Nitride finish, works perfectly. It's properly staked, machined & coated. It came head spaced to the barrel I also ordered & performed perfectly at the range. The Nitride finish is durable & makes cleanup a BREEZE. Top Notch products, thanks again guys... on 22nd Dec 2016

    3. Excellent finish

      The finish on this Bolt Carrier is fantastic. I have a hard time finding tool marks on it and the finish is nice and smooth to make it easy to clean. Having the bolt matched to the barrel is great and the laser engraving is top notch and deep so it can't wear off or anything like that on 15th Dec 2016

    4. Nice Bolt!

      I have installed a few of Faxon's Nitride finished Bolt Carrier Groups in 5.56 applications and I really like the finish, couple with their factory matching the bolt and serializing it with the barrel, when purchased together, its a great deal. The fit and function of the individual components make up a high quality installation at a very competitive market price.

      I recommend the Faxon Bolt!
