Faxon .458 Socom/ .450 Bushmaster Complete Bolt Carrier Group - Nitride
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.
Detailed Specifications:
- 9310 Tool Steel Bolt
- Full MIL-SPEC Heat Treatment

.458 SOCOM BCG
Just finished building my .458 SOCOM upper build. I put this in a side charging upper. No dust cover. This BCG looks beautiful. It goes into battery, buttery smooth. I don't expect any complications at the range next weekend, but if any arise, I'll update this review. For now, I couldn't be happier.
