Diamondback DB Barrel 7.62x39mm 10" 1:9.5 Twist Black Nitride - Carbine Length Medium Profile

The Diamondback DB Barrel is an AR-platform replacement barrel chambered in 7.62x39mm, intended for builders and shooters who want to assemble, complete, or replace the chamber of an AR-15-style upper. The Diamondback DB Barrel is supplied as a single barrel component suitable for installation into a standard AR-15 upper receiver.

Constructed from 4150 Chrome Moly Vanadium Steel and treated with a Black Nitride finish for corrosion resistance and surface hardness, this 10" barrel uses a Carbine-Length gas system paired with a medium profile contour that clears most standard handguards and supports a variety of muzzle devices. Its 1:9.5" twist rate is well suited to the 7.62x39 cartridge and a range of bullet weights.

This DB Barrel from Diamondback is a factory replacement barrel sold on its own, ready for installation with a standard AR-15 gas block, barrel nut, and a properly chambered 7.62x39 bolt and carrier group.
