Faxon 5.56 Gunner Bolt Carrier Group – Chameleon PVD

The Faxon 5.56 Gunner Bolt Carrier Group – Chameleon PVD is engineered to deliver exceptional reliability, durability, and performance for AR-15 rifles chambered in 5.56 NATO, .223 Remington, and .300 Blackout. Designed with a full-mass M16 profile, this BCG is built to handle rigorous use while maintaining smooth cycling and enhanced longevity, making it an excellent choice for shooters upgrading an existing rifle or completing a premium AR-15 build.

At the heart of this bolt carrier group is a bolt crafted from 9310 tool steel, a material known for its superior toughness and fatigue resistance. It undergoes full heat treatment, shot peening, and magnetic particle inspection (MPI) to ensure structural integrity under high-pressure use. The carrier itself is machined from MIL-SPEC 8620 steel and receives a salt bath nitride treatment, followed by a vibrant chameleon PVD (Physical Vapor Deposition) coating. This layered finish not only improves surface hardness and corrosion resistance but also offers a unique aesthetic with its multicolor sheen.

The Faxon 5.56 Gunner BCG features a properly staked gas key made from 4140 steel, secured with Grade 8 fasteners for long-term reliability. The cam pin is also 4140 pre-hardened steel, designed for consistent alignment and wear resistance. An S7 tool steel extractor ensures strong and consistent case extraction, even during rapid or suppressed firing conditions. The BCG also includes forward assist serrations and is fully compatible with standard AR-15 dust covers and upper receivers, making it a drop-in solution for most builds.

This bolt carrier group is full-auto rated and individually test fired, with each unit undergoing multi-point dimensional inspection to confirm perfect fit and function. Whether you’re setting up a hard-use patrol rifle, a competition rig, or a dependable defensive carbine, the Faxon 5.56 Gunner Bolt Carrier Group – Chameleon PVD offers the ruggedness and flair to meet your needs.
