The Faxon Firearms Big Gunner Barrel in .308 Winchester is built for shooters who demand long-range accuracy without the weight of a traditional heavy barrel. This 20-inch button-rifled barrel features a rifle-length gas system, offering improved recoil impulse and smooth cycling, while the Big Gunner profile strategically reduces weight forward of the chamber without compromising heat management or precision.

Constructed from high-strength 4150 CMV steel, this barrel is Salt Bath Nitride finished inside and out, providing exceptional corrosion resistance and long-lasting durability. The 1:10 twist rate supports a wide range of .308 Winchester bullet weights, delivering consistent accuracy for precision shooters and hunters alike.
The Big Gunner profile combines the rigidity of a heavy chamber area with a fluted-like taper toward the muzzle, offering superior balance and reduced barrel whip. It includes 5/8x24 muzzle threading for suppressors or muzzle devices, an LR-308 barrel extension compatible with DPMS-pattern AR10s, and an 11-degree target crown to enhance accuracy.
