Faxon Match Series 12.5" 6MM ARC Gunner Barreled Upper (FX-URG-M6A125GA1075-BU)
Construct a compact, high-performance 6MM ARC rifle with the Faxon Match Series 12.5" 6MM ARC Gunner Barreled Upper—a factory-assembled barreled upper assembly engineered for precision, lightweight handling, and versatility in short-barreled AR-15 platforms. This barreled upper includes the barrel, enhanced forged AR15 upper receiver, fixed low-profile gas block, carbine-length stainless gas tube, 10.75" M-LOK handguard, and MuzzLok® ported flash hider—ideal for hunting, practical precision builds, field carry, or any setup where 6MM ARC's flat trajectories and ballistics shine in a maneuverable package (requires BCG, charging handle, and lower to complete).
Built around a Match Series 12.5" Gunner-profile 6MM ARC barrel (416-R stainless steel, Nickel Teflon extension, 1:7.5 twist, carbine-length gas), paired with Faxon's enhanced forged AR15 upper receiver and modified feed ramps for reliable feeding. The fixed .750" low-profile gas block and carbine-length stainless gas tube deliver consistent cycling, while the MuzzLok® ported flash hider reduces flash and muzzle rise for improved control. The Streamline 10.75" M-LOK handguard provides modern accessory mounting and a clean, balanced front end. Made in Greater Cincinnati, Ohio with Faxon's lifetime warranty.
