M16 Bolt Carrier Group 5.56 / .223 - Chameleon PVD Finish

Bring smooth operation, exceptional durability, and a striking iridescent look to your rifle with the M16 Bolt Carrier Group 5.56 - Chameleon PVD. Precision-crafted and 100% American Made, this full-auto profile BCG is built to exceed strict performance standards while delivering a distinct multicolor aesthetic that makes any build stand out.

The carrier is machined from high-strength 8620 steel, heat-treated, and subjected to a final precision grind before receiving an ultra-tough Ionbond PVD Chameleon coating. At its core is a 9310 steel bolt that is heat-treated, shot-peened, Magnetic Particle Inspected (MPI), and treated with Blacknitride+™ by H&M for maximum wear resistance. Completed with a properly staked 4140 billet gas key secured with Grade 8 fasteners, an S7 tool steel extractor, and a 17-4 H-900 stainless steel firing pin, this complete assembly ensures flawless cycling and longevity.

Note: Due to the physical vapor deposition (PVD) process, the exact chameleon color gradient and hue may vary slightly from photograph to photograph, ensuring every unit has a unique finish.
