Diamondback Obsidian DB15 5.56 NATO 16 inch Barrel 30+1 Capacity 15 inch MLOK

The Diamondback Obsidian DB15 AR Rifle in black brings the DB15 series' tactical mindset to shooters who want a balanced, all-around 5.56 NATO platform for range days, competition stages, duty work, or varmint hunting. With a 16" 1:8 twist 4150 CMV barrel finished in Black Nitride and a mid-length gas system, this semi-auto rifle tames recoil and supports consistent accuracy with common 5.56 loads, while the DB Obsidian 1/2x28 muzzle brake reduces muzzle rise for faster follow-up shots. Built on forged 7075 T-6 aluminum upper and lower receivers, the Obsidian features a 15" M-LOK anti-rotation S-rail with full Picatinny and QD mounts for lights, optics, and accessories, plus a Magpul CTR stock and MOE K2 grip for comfortable ergonomics. Reliability comes from a shot-peened, MPI Mil-Spec 8620 carrier and Battle Arms Development ambidextrous controls including safety, bolt catch, and mag release, with a Breek Arms Warhammer Mod2 ambidextrous charging handle for fast manipulation. Weighing 6.6 lbs and measuring 33—36.25" OAL, the DB1784K001 is FFL-required and ready as a hard-use AR-15 platform for serious shooters who value durability, modularity, and proven components.
