Seeing "MIL-SPEC" as just the starting point, Faxon set out to ensure the best options are available for our demanding customers. 

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 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. 

*Not Compatible w/ Faxon 6.5 Grendel Barrels

    Doesn't work, not the BCG fault

    Posted by Vincent Gamble on May 5th 2022

    I have a 7.62 AR build I've been working on. I picked up this BCG hoping it would make a real difference and help the rifle run more consistently. It didn't.

    Ordered this type 1 bcg for my 7.62x39 build. Very well made and has a sharp look to it. Have ran a couple hundred rounds through it so far trying to work out kinks like extracting, feeding, light strikes. None of which seem to have to do with the bcg from what I can tell. So far it has not shown signs of wear. I will definitely be interested to see how the extractor holds up with steel cased rounds. Would have given it a 5 stars but have not used enough to say it’s going to hold up to the abuse.
