Faxon Firearms AR-10 Duty Big Gunner 308 Win 18" Barrel

The Big Gunner is the bigger brother to Faxon's 5.56 Gunner, with a medium taper behind the gas block and a thinner taper ahead of it to reduce weight and keep rigidity. On this 18" 308 Win barrel, rifle length gas gives a soft impulse, and it works as a suppressor host.

The .750" gas block journal is 1.9" long, so it takes long blocks or aftermarket piston kits. It is button rifled, salt bath nitrided inside and out, and has a DPMS compatible LR-308 extension, 5/8-24 threads and an 11 degree target crown. A good choice for competition or a duty style rifle, at 2.13 lbs.
