Always Armed 18" .308 Win Upper Receiver - 15" M-LOK Rail

Step up your long-range performance and tactical capability with the Always Armed 18" .308 Win Upper Receiver. Built on a popular DPMS pattern upper receiver platform, this high-performance upper receiver assembly is engineered to deliver reliable cycling, heavy-duty durability, and exceptional accuracy for target shooting, hunting, and tactical applications.

At the heart of this assembly is a precision-machined 4150 Chrome Moly HBAR contour barrel chambered in .308 Winchester with a versatile 1:10 twist rate to consistently stabilize medium-to-heavy projectiles. A mid-length gas system helps soften felt recoil while extending internal component longevity. Enclosing the barrel is a sleek 15" Free Floating M-LOK Rail, providing full-length top rail space and ample M-LOK attachment real estate for bipods, lights, and foregrips. Completed with a classic A2 Flash Hider on a 5/8x24 thread pattern and finished with a hard-coat black anodizing, this upper assembly is ready to attach directly to your DPMS-pattern .308 lower receiver.
