The Diamondback Barrels 556 16" carbine barrel is a professional-grade component designed for modern sporting rifle platforms and AR-pattern firearms. It is ideal for operators, tactical shooters, and law enforcement personnel who require reliability and accuracy in various environments. This barrel is built to withstand sustained fire while maintaining performance.
Constructed from 4140 chromoly steel and finished with a mil-spec black nitride coating, this barrel is resistant to corrosion and fouling. The 1:9 twist rate stabilizes standard 55–62-grain 5.56 NATO projectiles, making it suitable for practical shooting distances. The carbine-length gas system is designed to optimize cycling and reliability.
This barrel is compatible with any direct impingement AR-15 or M4-pattern rifle, featuring standard 0.750" gas block mounting and 1/2x28 threading for sound suppressors or muzzle devices. Its medium profile strikes a balance between weight and stiffness, minimizing harmonic vibration for improved precision.
