20" AR-15 .350 Legend Barrel

Maximize velocity and downrange accuracy for your straight-wall cartridge build with the 20" AR-15 .350 Legend Barrel. Engineered specifically for big-game hunters and modern sporting rifle enthusiasts, this full-length barrel squeezes maximum ballistic performance out of the popular .350 Legend cartridge—making it ideal for deer hunting in straight-wall state zones.

Machined from high-grade 4150 Chrome Moly Vanadium (CMV) steel, this barrel delivers superior heat resistance, durability, and sustained precision. It features a heavy-duty Parkerized finish that protects against corrosion and harsh outdoor environments, while the 1:16 right-hand twist rate is precision-tuned to properly stabilize standard-weight .350 Legend factory ammunition for clean flight trajectories and tight groups.

Designed for reliable cycling, it utilizes a standard .750" gas block journal and a carbine-length gas system. The muzzle is cut with a standard 5/8x24 TPI thread pitch, giving you full compatibility with a wide selection of .350 Legend muzzle brakes, flash hiders, and suppressors.
