Diamondback DB Barrel 7.62x39mm 16" 1:9.5 Twist Black Nitride - Carbine Length Medium Profile

The Diamondback DB Barrel is an OEM-quality 7.62x39mm replacement barrel designed for AR-15 platform builds. Cut from 4150 Chrome Moly Vanadium steel and finished in a rugged black nitride coating, this barrel delivers excellent corrosion resistance and long-term durability for high-volume shooting.

The barrel measures 16" in length and features a carbine-length gas system with a medium profile contour. A 1:9.5 twist rate reliably stabilizes a broad range of 7.62x39mm bullet weights, making it ideal for both completing a custom build and replacing a worn factory barrel. The black nitride finish provides excellent corrosion resistance, and the medium profile keeps the barrel light enough for a well-balanced rifle.

Whether you are finishing a 7.62x39mm AR-15 build from the ground up or swapping out a barrel during a rebuild, this Diamondback DB Barrel offers a direct-fit replacement with the materials, finish, and gas system geometry needed for dependable performance.
