Faxon Firearms® Superfinished 5.56 Gunner Lightweight Bolt Carrier Group | Chrome
Lightweight Design. Full-Mass Reliability.
The Faxon Firearms® Superfinished 5.56 Gunner Lightweight Bolt Carrier Group | Chrome combines the reliability of a full-mass M16 BCG with the speed and balance advantages of Faxon’s Gunner lightweight profile. Precision-machined and treated with Faxon’s advanced Superfinish process, this BCG delivers ultra-smooth operation, easy cleaning, and long-term durability. The chrome finish provides a classic, corrosion-resistant exterior that minimizes friction and wear, while maintaining the polished aesthetic that builders and professionals appreciate.
Optimized for Speed and Control
Engineered to reduce reciprocating mass, the Gunner Lightweight BCG allows for faster cycling and reduced felt recoil—ideal for competition, defensive, or lightweight AR-15 builds. Despite its weight reduction, Faxon maintains critical mass in the areas necessary for reliable lockup, extraction, and ejection. The result is smoother operation and faster follow-up shots without sacrificing reliability.
Superfinished for Ultimate Smoothness
Faxon’s Superfinish process polishes all contact surfaces to near-mirror smoothness, minimizing friction and carbon fouling. This results in quieter operation, improved consistency, and extended service life for the bolt, carrier, and firing components—even during high-volume shooting.
