Diamondback Firearms DB1984K001 Obsidian 5.56 11.5" 31-Round Pistol

The Diamondback Firearms DB1984K001 Obsidian 5.56 11.5" 31-round pistol delivers compact firepower for operators who demand modularity and performance in tight spaces. Purpose-built for tactical teams, law enforcement units, and civilian shooters who prioritize maneuverability without sacrificing capacity, this short-barreled rifle platform fills the gap between full-size carbines and traditional handguns. The 31-round magazine capacity ensures extended engagement capability while the 11.5-inch barrel maintains effective 5.56 NATO velocity for intermediate distances common in dynamic entries, vehicle operations, and home defense scenarios.

The Obsidian platform features a flat-top design accommodating modern optics and aiming systems, while the pistol configuration allows for optimal ergonomics and quick-target acquisition. At 7.48 pounds and measuring just 9 inches in length, weight distribution is engineered for sustained accuracy during tactical transitions and room-clearing operations. The 5.56 NATO chamber delivers proven ballistic performance across barrier-penetration and soft-target scenarios, while the 31-round magazine reduces reload requirements during extended engagements—critical for operators working in communication-compromised or high-stress environments.

This platform benefits law enforcement SWAT teams, military support units, armed security professionals, and equipped civilians seeking a next-generation defensive rifle platform. The compact profile integrates seamlessly into vehicle mounts, close-quarters environments, and scenarios where rifle capability is essential but full-length carbines create operational liability. Compatible with standard 5.56 NATO ammunition and mil-spec accessories, the Diamondback Obsidian 5.56 11.5" pistol represents a battle-proven design philosophy: maximum effectiveness in minimum footprint.
