Diamondback DB1984K001 Obsidian 5.56 NATO 11.5" Pistol 30+1

The Diamondback Obsidian DB1984K001 delivers compact firepower with full-size capability in a precision-engineered 5.56 NATO pistol platform. This configuration maximizes maneuverability while maintaining ballistic performance through its optimized 11.5-inch barrel length. The black nitride finish provides superior corrosion resistance and reduces maintenance requirements.

What Makes This Different

The Obsidian platform incorporates a free-floating 11-inch M-LOK handguard that extends nearly to the muzzle, providing maximum accessory mounting real estate while maintaining structural rigidity. Unlike standard carbine-length systems, this configuration offers improved balance and handling characteristics. The SBA5 adjustable brace system delivers five positions of length adjustment with secure lockup at each setting.

Field performance centers on the barrel's optimized length-to-velocity ratio, delivering effective terminal ballistics while maintaining compact dimensions. The platform excels in close-quarters applications where maneuverability matters, while the free-floating handguard maintains accuracy potential for precision work. Weather-sealed components and nitride treatment ensure reliable function across temperature and humidity extremes.
