Faxon Firearms 5.56/300 BLK M16 Bolt Carrier Group - Chameleon PVD

The Faxon Firearms 5.56/300 BLK M16 Bolt Carrier Group - Chameleon PVD is a high-performance bolt carrier group that exceeds MIL-SPEC standards. Designed with our demanding customers in mind, this bolt carrier group offers unparalleled performance and value.

One of the key improvements we have made is the use of 9310 tool steel for the bolt. This material is stronger than the traditional C158 steel, ensuring reliable action even under the highest pressure hand loads. The assembly is also nitrided to increase surface hardness, reduce resistance, and provide superior corrosion resistance compared to chrome and phosphated bolt carrier groups.

To guarantee the quality of our product, all bolts undergo a thorough MPI testing to ensure the material is sound and free from defects. The bolt lugs are chamfered at 45 degrees for reliable action, and the entire bolt carrier group is Superfinished to reduce friction, improve smoothness of operation, and minimize fouling.

Not only is this bolt carrier group compatible with full-auto fire control groups and new multi-stage trigger systems, but the gas keys are staked with grade 8 fasteners for long-lasting service. Additionally, the carrier and key are made from MIL-SPEC 8620 and 4140 steel materials respectively, both fully heat-treated for maximum durability.

The extractor is constructed from S7 tool steel and is fully heat-treated, shot peened, and salt bath nitrided for exceptional strength and reliability. The cam pin is made from pre-hardened 4140 steel and also undergoes a salt bath nitride treatment.

Please note that when ordering and using this bolt carrier group with barrels not specifically checked by Faxon for headspacing, it is important to perform a headspace check to ensure safe and reliable function. We recommend using Pacific Tool & Gauge headspace kits for accurate measurements.

With its superior construction, enhanced performance, and exceptional value, the Faxon Firearms 5.56/300 BLK M16 Bolt Carrier Group - Chameleon PVD is the ideal choice for discerning firearm enthusiasts.
