Diamondback DB1916B061 DB15 300 AAC 30+1 10" Flat Dark Earth Cerakote Heavy Barrel 9" M-LOK Handguard 7075-T6 Aluminum SBA3 Brace Magpul MOE Grip
The Diamondback DB15 300 AAC Blackout pistol is a compact, home-defense-ready AR platform built on a forged 7075-T6 aluminum lower and upper receiver. Chambered in 300 AAC Blackout with a 10-inch heavy barrel, this 30+1-capacity AR pistol delivers deep, reliable power in a package that handles tight quarters without sacrificing accuracy. Finished in Flat Dark Earth Cerakote, it strikes a balance between professional aesthetics and rugged durability—ideal for home security, short-range hunting, or shooters who want an AR pistol that doesn't compromise on build quality.
The heart of this rifle is a 10-inch 4150 CrMoV barrel with 1:8 twist rate, Black Nitride finished for corrosion resistance. The pistol-length direct impingement gas system keeps the action reliable across supersonic and subsonic 300 Blackout loads. Inside, a shot-peened, magnetic particle inspected Mil-Spec 8620 carrier ensures the bolt carrier group meets military standards—the kind of attention to internals that separates a solid build from a throw-together.
Ergonomics follow a proven formula: a 9-inch M-LOK rail provides genuine rail estate for lights, lasers, or optics without the bloat; the Magpul MOE grip offers a familiar, textured purchase; and the SB Tactical SBA3 brace gives you a shoulderable platform while keeping the footprint compact. Standard Mil-Spec trigger, A2 flash hider (5/8 x 24 threaded), and a Magpul Gen M3 PMAG 30-round magazine round out a no-nonsense setup. At 5.7 pounds and just 26 inches collapsed, this pistol lives up to its name without feeling like a compromise.
