The rifle-length gas system on an 18-inch barrel delivers a soft impulse and broad tuning flexibility while the Gunner contour keeps weight and handling in check for practical rifles that still need reach. – Duty Series barrels start with 4150 CMV steel and standard button rifling then receive QPQ salt bath nitride inside and out for strong corrosion resistance and long service life. The Gunner (Big Gunner) profile uses a sturdier taper behind the gas block for rigidity and a slimmer forward section to reduce front-end weight-an excellent combination for general-purpose builds and suppressor-ready setups. – Proudly American-made by a family-owned manufacturer in Greater Cincinnati Ohio each barrel is built for consistent performance and backed by the Faxon standard of quality. – Key Benefits – Gunner (Big Gunner) balance: Medium taper behind the gas block for stability with reduced forward weight for handling. – 4150 CMV steel: Duty-grade strength and heat tolerance for real-world use. – QPQ nitride inside & out: Corrosion and wear resistance for long service life. – Rifle-length gas: Smooth recoil impulse and consistent cycling on 18 builds. – 11° target crown (non-recessed): Clean repeatable shot exit for consistency. – 5/8×24 muzzle threads: Standard interface for .30-cal muzzle devices and suppressors (verify alignment/mount specs). – MPI inspected: Quality control focused on dependable performance. – Ideal Use Cases – General-purpose AR10 builds: A versatile 18 .308 configuration with rifle-gas smoothness. – Field & hunting rifles: Balanced profile for carry comfort and practical accuracy. – Training & high-use setups: QPQ protection helps resist corrosion and wear. – Suppressor-ready builds: 5/8×24 threads support common .30-cal devices (verify suppressor rating and alignment). – Specifications – Platform / Series AR10-Duty Series – Caliber .308 Win – Length 18 – Profile Gunner (Big Gunner) – Twist Rate 1:10 – Material 4150 CMV Steel – Rifling Standard Button Rifled – Finish Salt Bath Nitride (QPQ)- inside & out – Gas System Rifle-length – Gas Block Diameter .750 – Gas Block Journal Length 1.9 – Muzzle Threads 5/8×24 TPI – Extension DPMS / LR-308 Compatible-Black Oxide – Crown 11° Target Crown (non-recessed) – Inspection Magnetic Particle Inspected (MPI)
