Faxon Firearms .308 20″ Rifle Length AR-308/AR-10 Barrel with Big Gunner Profile in Black Nitride
The .308 Big Gunner barrels are the big-brother to Faxon’s famous 5.56 Gunner Barrels. This barrel features a medium taper behind the gas block. The gas block journal is .750″ and it has a 1:10″ twist. Also, from the gas block journal forward, these is now a thinner taper which reduces weight while still maintaining rigidity for high rates of fire. Gunner barrels are perfect for competition or duty use.
