FAXON DUTY SERIES GUNNER PROFILE 16" MID-LENGTH .308 WIN AR10 BARREL
Faxon Duty Series AR10 Barrel — Gunner Profile 16" .308 Win (1:10 Twist, Mid-Length Gas)
4150 CMV steel • Button rifled • Salt bath nitride (QPQ) inside & out • Gunner profile • 11° target crown (non-recessed) • Mid-length gas • .750" gas block journal • 5/8x24 TPI • LR-308 / DPMS compatible
The Faxon Duty Series Gunner Profile 16" .308 Win AR10 barrel is built for shooters who want a fast-handling, do-it-all .308 carbine without giving up real-world durability. This mid-length gas setup balances dwell time and recoil impulse for a smoother, more controllable AR10 while keeping the overall package compact.
Duty Series barrels are machined from 4150 CMV steel and feature traditional button rifling for proven accuracy and long service life. A salt bath nitride (QPQ) treatment inside and out helps resist corrosion and wear in harsh conditions and high-round-count training.
The Gunner profile is engineered for balance—keeping strength where it matters while reducing unnecessary forward weight for quicker transitions. Like every Faxon barrel, it’s proudly American-made by a family-owned manufacturer in Greater Cincinnati, Ohio.
