Faxon Firearms Superfinished 5.56 NATO Gunner Lightweight Bolt Carrier Group - Chrome

The Faxon Superfinished 5.56 Gunner Lightweight BCG is a premium AR-15 upgrade designed for smooth operation, reduced weight, and long-term reliability. Weighing just 8.5 oz and machined from high-strength 9310 tool steel, its lightweight design delivers smooth cycling while remaining rated or full-auto use.

A hard chrome finish rated at 68–72 HRC provides excellent wear resistance, corrosion protection, and lubricity, resulting in faster cycling, reduced fouling, and easier cleaning. The superfinished carrier body and Gunner profile further reduce friction for consistent performance under high round counts.
