18" 5.56 1:7 RIFLE LENGTH BARREL

Maximize velocity and smooth out your recoil impulse with this 18" 5.56 Rifle Length Barrel. Proudly Made in the USA, this precision barrel offers the ideal balance of maneuverability and extended-range ballistic performance, making it an excellent choice for DMR (Designated Marksman Rifle) builds, target shooting, and hunting.

Precision-machined from ultra-durable 4150 Chromoly Steel, this barrel features a classic M4 contour profile that optimizes weight distribution without sacrificing thermal stability. Chambered in 5.56x45mm NATO (safely accepts both 5.56 NATO and .223 Remington ammunition), it is cut with precision M4 feed ramps to guarantee reliable cartridge feeding from magazine to chamber under high rates of fire.

Equipped with a 1:7 twist rate, this barrel excels at stabilizing heavier projectile weights (62gr to 77gr+), delivering tack-driving accuracy downrange. The rifle-length gas system pairs with a standard .750 gas block journal to provide an ultra-soft recoil profile and significantly reduce wear on internal bolt components. Capped with standard 1/2x28 TPI threads, it readily accepts a wide variety of flash hiders, muzzle brakes, and suppressor mounts.
