Product Description

The Faxon Firearms 5.56 NATO M16 Bolt Carrier Group (BCG) in Chameleon PVD is a premium AR-15/M16 upgrade built for shooters who want smooth cycling, strong corrosion resistance, and dependable function under hard use. Faxon treats MIL-SPEC as a baseline, enhancing key wear surfaces and critical components for long-term reliability. The bolt is made from 9310 tool steel, fully heat treated, shot peened, and Magnetic Particle Inspected (MPI) to help ensure material integrity. The bolt and carrier are salt bath nitrided to increase surface hardness and improve corrosion resistance, while the carrier and gas key feature a color-shifting Chameleon PVD coating for added wear resistance and a distinctive finish.

Reliability-focused details include chamfered bolt lugs for consistent cycling, an S7 extractor, and a spring/insert/“Crane” O-ring installed. As an M16-pattern carrier, it is full-auto compatible, making it a strong choice for duty rifles, training carbines, and high-round-count setups where durability and ease of maintenance matter.
