Nitride Barrel with 11 Degree Target Crown

Low cost and high value components can be hard to come by – luckily, Diamondback Firearms delivers with their barrels.  This carbine length AR-15 barrel features a corrosion resistant black nitride finish inside and out, ensuring longevity and protection from the elements.  The carbine gas system is a proven system for this barrel length, providing sufficient pressure for cycling steel case ammunition

The 1-8 twist ensures compatibility with a wide variety of ammo, from standard full metal jacket rounds for practice, to heavier match-grade loads where higher accuracy is key.  Plus, the muzzle receives an 11 degree target crown, which helps tighten groups even on a budget-friendly barrel like this one.

16" Diamondback carbine barrel

Very nice. Great deal for a good quality item. Easy installation with a perfect fit into the upper reciever. Couldn't be happier.

Very solid barrel

This is a great deal from AT3. The barrel exhibits quite good quality and is free of any flaws. It has a dimple for the gas block set screw which, on my barrel, aligned the gas block perfectly. Easy install into the receiver. Overall, I couldn't find a better deal anywhere online. AT3 certainly is the place to shop for AR15 parts and gear.
