Diamondback Firearms DB1758K071 DB15 5.56 NATO 16" 31-Round Carbine

The Diamondback Firearms DB15 5.56 NATO 16" carbine is a modern intermediate rifle engineered for law enforcement, military, and civilian tactical operators who demand reliability in dynamic environments. Built on the proven AR-15 platform, this 31-round carbine delivers the versatility and modularity that professionals expect, whether deployed for patrol operations, training exercises, or home defense.

The 16-inch barrel strikes the critical balance between velocity, maneuverability, and accuracy—ideal for confined spaces and rapid target engagement where full-length rifle configurations become unwieldy. The DB15 platform features a mid-length gas system that optimizes reliability and controllability across standard 5.56 NATO ammunition without excessive recoil impulse. The design integrates modern ergonomic controls and accepts standard AR-15 aftermarket components, enabling rapid customization for optics, grips, and accessories tailored to specific mission requirements.

At 12.8 pounds, the weapon remains shoulderable for extended operations while the 31-round magazine capacity provides sustained suppressive fire and flexibility in high-stress scenarios without constant reloads. Law enforcement SWAT teams and military personnel transitioning to civilian roles will find this carbine practical for vehicle operations and tactical entries.
