Diamondback DB Barrel 5.56x45mm NATO 16" 1:8 Twist Black Nitride - Carbine Length Medium Profile

The Diamondback DB Barrel is a 16-inch 5.56x45mm NATO replacement barrel built for the AR-15 platform, designed as a direct-fit upgrade or build component for any standard mil-spec upper receiver.

Constructed from 4150 Chrome Moly Vanadium steel with a black nitride finish for enhanced corrosion resistance, wear resistance, and extended service life, this barrel is paired with a carbine-length gas system and a medium profile contour that balances rigidity and weight for a wide range of carbine builds.

The barrel features a 1:8" twist rate, a versatile stabilization rate that handles the full spectrum of 5.56 NATO and .223 Remington bullet weights - from light varmint projectiles through heavier match and duty loads.

Whether you are replacing a worn-out barrel or completing a fresh build, the Diamondback DB Barrel brings Diamondback's quality control and reputation for value to your next AR-15 project.
