A Trim, Maneuverable Barrel With Nearly Match-Grade Accuracy Potential

The Faxon Firearms Big Gunner .308 Win. Barrel’s profile is the big brother to Faxon’s popular 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. 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. Keeping weight at the rear maximizes rigidity and maneuverability.

Each Big Gunner .308 Win. barrel is machined from stress-relieved 4150 chrome moly steel, and finished it with a tough, wear-resistant Nitride finish.

  • Fits DPMS LR-308 Gen1 pattern upper receiver OR Armalite AR-10 upper.
  • 1-10" twist
  • 11° target crowned muzzle
  • 5/8"-24 threaded muzzle
  • Each barrel individually checked for headspace with precision gauges

Faxon Big Gunner .308 Win. Barrels are available in 16" length with a mid-length gas system, as well as 18" and 20" length gas systems.

Gun Tech Note: Faxon highly recommends properly checking the head space between your barrel and bolt before firing your new barrel. For accurate measurement, Faxon recommends using PTG headspace gauges with their barrels.
