Diamondback 7.62x39mm 7" Heavy Profile Barrel – Black Nitride
The Diamondback 762X39P7H50B95R is a high-performance AR-platform barrel designed for shooters looking to build a compact, hard-hitting pistol or SBR (Short Barreled Rifle). While many short-barreled setups struggle with the ballistics of the 7.62x39mm round, Diamondback has optimized this 7-inch barrel with a 1:9.5" twist rate to ensure reliable stabilization and accuracy. The Heavy Profile contour provides the structural rigidity needed to handle rapid fire and manage heat more effectively than thinner "pencil" profiles.
Crafted from 4150 Chrome Moly Vanadium Steel, this barrel is finished with a Black Nitride (QPQ) coating. This advanced treatment creates a surface that is harder than chrome lining, offering exceptional corrosion resistance and a low-friction bore that significantly extends the service life of the barrel. It features a Pistol-Length Gas System, which is essential for ensuring reliable cycling in such a short configuration, especially when running the high-pressure 7.62x39mm cartridge.
Ready for your favorite muzzle device, the barrel comes with a standard 5/8x24 threaded muzzle. Whether you are building a "backpack gun" or a specialized tactical rig, this Diamondback barrel provides the rugged American-made quality required for a dependable, sub-compact powerhouse.
