20" 308 Winchester 1:10 Twist Barrel

Maximize long-range accuracy and velocity out of your heavy-caliber platform with this 20" AR-10 .308 Rifle Length Barrel. Precision-engineered for long-range precision, hunting, and tactical applications, this barrel delivers optimal ballistic efficiency while keeping front-end weight balanced.

Crafted from high-grade 4150 Chromoly Steel, this barrel features a Light SOCOM profile that reduces excess weight without compromising rigidity or heat dissipation during rapid fire. Treated with a sleek Black Nitride finish (QPQ Melonite), both the bore and exterior surfaces offer exceptional wear resistance, reduced friction, and superior protection against corrosion.

Chambered in .308 Winchester / 7.62x51mm NATO, it features precision-cut M4 feed ramps for reliable cartridge feeding. The 1:10 twist rate provides versatile stabilization for mid-to-heavy projectile weights (150gr to 175gr+). Paired with a rifle-length gas system and a .750 gas block journal, it delivers a soft, smooth recoil impulse that reduces wear on internal receiver components. Capped with standard 5/8x24 TPI threads, it is ready to host your choice of muzzle brakes, flash hiders, or suppressor adapters.
