Diamondback 7.62x39mm 10" Medium Profile Barrel – Black Nitride
The Diamondback 762X39C10M50B95R is a versatile, American-made barrel designed for shooters who want a balance of compact maneuverability and reliable cycling in an AR-47 platform. At 10 inches in length, this barrel utilizes a Carbine-Length Gas System. This is a critical design choice, as the longer gas system (compared to pistol-length) helps smooth out the cycling of the 7.62x39mm round, reducing parts wear and providing a more manageable recoil impulse for pistol or SBR (Short Barreled Rifle) builds.
Machined from 4150 Chrome Moly Vanadium (CMV) Steel, the barrel features a Medium Profile contour. This profile strikes the perfect "Goldilocks" balance: it’s rigid enough to maintain accuracy during high-volume strings of fire, yet light enough to keep the front end of your firearm quick and easy to point. The Black Nitride finish provides a deep, non-reflective surface that is incredibly resistant to corrosion and easier to clean than traditional chrome lining. With a 1:9.5" twist rate and button-rifled 5-groove bore, it is optimized to stabilize the most common 122gr to 124gr 7.62x39mm loads with surgical consistency.
The barrel comes standard with M4 feed ramps for reliable chambering and a 5/8x24 threaded muzzle, making it ready for your favorite suppressors, flash hiders, or muzzle brakes. Whether you are building a dedicated truck gun or a tactical range toy, the Diamondback 10" barrel offers a robust and refined foundation.
