Questions & Answers
This will fit 300 blackout right? Manufacturer Answer

Yes, this BCG can be used in a .300BLK rifle

by Faxon Firearms, Manufacturer, February 19, 2026
May be dumb to ask such a thing for clarity sake…but M16 carrier group compatible with AR-15 platforms??? Manufacturer Answer

Yes, the M16 and AR-15 are the same base system. This BCG is an M16 "profile," designating that it matches the dimensions and weight of the BCG from a Mil-Spec M16 rifle or M4 Carbine, but it is compatible with nearly all commercial AR-15 pattern rifles.

Product Info for Faxon Firearms 5.56 M16 Bolt Carrier Group

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.image
