Diamondback DB15 Obsidian Features The Diamondback DB15 Obsidian pairs a carbine-length gas system with a pinned gas block a combination that enhances cycling reliability while smoothing out recoil impulse compared to an unpinned setup giving shooters a more controllable pistol for both dynamic and precision shooting. The 11.5 chrome moly vanadium barrel wears a black nitride finish for corrosion resistance and is threaded 1/2x28 to accept the included DB Obsidian muzzle brake which further reduces felt recoil and muzzle rise during rapid strings of fire. The 7075 T-6 aluminum receiver is finished in black hardcoat anodize and rides on an A3 flattop rail giving shooters a stable standard optics mounting surface. An 11 M-LOK handguard gives shooters extensive real estate for mounting lights foregrips and other accessories to configure the pistol for their specific role. The included SB Tactical SBA5 brace and Magpul MOE K2 grip work together to deliver superior ergonomics and control letting shooters manage the compact platform confidently in both close-quarters and precision shooting scenarios. A Battlearms ambidextrous safety and mil-spec trigger round out a controls package built for shooters of any handedness. The Diamondback DB15 Obsidian in 5.56 / .223 Rem with its included SBA5 brace delivers a well-rounded reliable AR pistol platform ready for a wide range of shooting tasks.
