They have updated the previous Medium-Taper profile taking into account customer feedback, optimizing the barrel to meet the Gunner brand's high standards. The .308 Big Gunner profile barrels are the big-brother to Faxon's 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. **Shop with KYGUNCO for the best selection, competitive pricing, and exceptional customer service.
