Faxon .308 / 6.5 Creedmoor / 8.6 BLK Bolt Carrier Group, Gen 2 – Nitride

6.5 Creedmoor & 8.6 BLK Compatible!

The Faxon Gen 2 Bolt Carrier Group is engineered for superior performance in .308, 6.5 Creedmoor, and 8.6 BLK chambered rifles. Designed with innovation and precision, this BCG incorporates advanced materials, enhanced durability, and reliability-focused upgrades for demanding shooters and high-performance builds. Compatible with DPMS Gen 1 pattern receivers, it’s a versatile and robust solution for large-frame AR platforms.

This BCG features a bolt constructed from 9310 tool steel—stronger than the traditional C158—with full MIL-SPEC heat treatment and shot peening for maximum durability. Chamfered 45-degree bolt lugs ensure smooth cycling and enhanced reliability, even under the stress of high-pressure handloads and lightweight bolt carrier builds. The entire assembly is QPQ salt bath nitrided for increased surface hardness, superior corrosion resistance, and reduced friction compared to chrome or phosphate coatings.

Faxon takes reliability a step further by applying a Superfinish to the carrier, improving smoothness of operation and reducing fouling buildup. The gas key is made from 4140 steel, secured with Grade 8 fasteners, and fully staked to MIL-SPEC standards to ensure lifetime service. All bolts are MPI tested to confirm structural integrity and performance under extreme conditions.
