Diamondback Firearms DB1916K101 DB15 5.56 10" 31-Round Pistol

The Diamondback Firearms DB1916K101 DB15 5.56 10" pistol is a compact, magazine-fed tactical platform engineered for close-quarters engagement, home defense, and professional duty applications where barrel length and overall size are operationally critical. Purpose-built for operators who require rifle-caliber velocity and accuracy in a form factor that bridges the gap between traditional handguns and full-size rifles, this 5.56 NATO chambered pistol delivers decisive terminal performance without sacrificing portability or maneuverability in confined spaces.

Weighing 7.2 pounds and measuring just under 31.6 inches overall, the DB15 features a 10-inch barrel optimized for 5.56 NATO ballistics while maintaining the low-impulse recoil signature characteristic of intermediate cartridges fired from pistol-length systems. The firearm ships configured to accept standard 31-round AR-type magazines, providing substantial onboard ammunition capacity for extended engagements without magazine changes. The compact configuration and weight distribution make this platform exceptionally maneuverable in vehicle interiors, stairwells, and other constrained tactical environments where traditional rifles prove unwieldy.

This pistol platform appeals to law enforcement tactical teams, armed security professionals, and civilian operators seeking AR-pattern familiarity with reduced overall footprint. The 31-round magazine capacity and 5.56 NATO chambering make it compatible with standard AR ammunition and aftermarket magazines, ensuring logistics simplicity and parts availability across professional and civilian inventories. Installation of arm braces or stabilizing devices, compliance verification with current NFA regulations, and local jurisdictional restrictions should be confirmed before purchase and deployment.
