18" .308 Winchester 1:10 Twist Barrel

Maximize precision and maneuverability on your heavy-caliber build with this 18" AR-10 .308 Rifle Length Barrel. Engineered to strike the perfect balance between high muzzle velocity and front-end agility, this barrel is ideal for tactical setups, long-range target shooting, and medium-to-large game hunting.

Crafted from high-grade 4150 Chromoly Steel, this barrel features a Light SOCOM profile that eliminates unnecessary front-end weight while maintaining exceptional rigidity and heat dissipation. Treated with a slick Black Nitride finish (QPQ Melonite), both the bore and exterior surfaces deliver superior wear resistance, low friction, and maximum protection against harsh environmental elements.

Chambered in .308 Winchester / 7.62x51mm NATO, it features precision-cut M4 feed ramps to guarantee smooth and reliable cycling. The versatile 1:10 twist rate provides rock-solid stabilization across mid-to-heavy projectile weights (150gr to 175gr+). The rifle-length gas system pairs with a standard .750 gas block journal to deliver an ultra-smooth recoil impulse and reduce wear on internal action components. Capped with standard 5/8x24 TPI threads, it is ready for your choice of muzzle brakes, flash hiders, or suppressor mounts.
