The Diamondback 5.56x45mm AR pistol delivers serious firepower in a compact, maneuverable platform. Built on a forged 7075 T-6 aluminum upper and lower, this 7-inch barreled AR pistol handles 5.56 NATO/.223 Rem ammunition and comes ready to shoot with a 30-round PMAG, standard trigger, and MOE grip. At just 5.1 lbs and 23 inches overall, it's lightweight and quick enough for home defense, truck storage, or range work where a full-length rifle doesn't fit the mission.
The heavy 4150 CrMov barrel wears black nitride finish and runs a pistol-length gas system with a shot-peened, magnetic particle-inspected MIL-spec bolt carrier group for reliability under hard use. That 1:8 right-hand twist stabilizes a wide range of 5.56 loads. The 6-inch M-LOK handguard gives you clean rail space to add optics, lights, or laser without clutter, while the A2 flash hider (1/2x28) keeps muzzle signature down on indoor ranges or in low-light scenarios.
No sights come mounted, which means you're free to run your choice of optic or iron sights—whether you're setting up a red dot build or going with traditional backup irons. The buffer tube foam pad provides a soft shoulder interface, though many users upgrade with an SBM4 or similar stabilizing brace for even better control. This is a no-frills, feature-rich platform that works hard and won't empty your wallet.
