We've updated our previous Medium-Taper profile, taking customer feedback into account and optimizing the barrel to meet the Gunner brand's high standards.The .308 Big Gunner profile barrels are the big brother to our famous 5.56 Gunner barrels. The Big Gunners feature a medium-taper behind the gas block. The gas block journal is set to .750" for compatibility with most common gas blocks and 1.9" in length for long blocks or aftermarket piston kits. From the gas block journal forward, we use a thinner taper, designed to reduce weight yet maintain rigidity for high rates of fire and as a suppressor host.The Gunner barrels are ideal for any competition or duty use. When the seconds count, count on the Gunner profile.Specifications Barrel Material: 4150 QPQ Barrel Type: Button Rifled Barrel Caliber: .308 WIN Barrel Twist: 1:10 Barrel Length: 18" Barrel Profile: BIG GUNNER Barrel Gas System: Rifle Inside Finish: Salt Bath Nitride Outside Finish: Salt Bath Nitride Muzzle Thread: 5/8-24 TPI Gas Block Diameter: .750" Gas Block Journal Length: 1.9" Barrel Extension: LR-308 (DPMS Compatible) Weight: 2.13 lbs Magnetic Particle Inspected! 11-degree Target Crown
