Diamondback Firearms Db15 300blk 10" 30-Round Threaded Barrel AR Pistol

The Diamondback Firearms DB15 300 Blackout 10" 30-Round Threaded Barrel AR Pistol is a compact, mission-ready platform engineered for close-quarters engagement and controlled suppressed fire. Designed for operators who demand versatility without sacrificing terminal performance, this AR pistol bridges the gap between a full-size rifle and a dedicated pistol, delivering the ergonomics and modularity of the AR platform in a compact package.

The threaded barrel allows seamless integration with sound suppressors, making it ideal for tactical operations where noise discipline is critical. Built on a proven AR pistol architecture, the DB15 features a 10-inch barrel optimized for the subsonic 300 Blackout cartridge, delivering consistent velocity curves even with suppressed ammunition. The 1/2x28 threaded muzzle accommodates standard suppressor mounts, reducing back-pressure sensitivity and improving reliability.

The 30-round detachable magazine provides ample capacity for dynamic scenarios, while the AR-pattern ergonomics—including ambidextrous controls and a pistol grip—ensure rapid target transitions and manipulation under stress. Weighing 1.5 lbs, this platform remains maneuverable in vehicle and confined-space operations without excessive weight penalty, making it genuinely practical for serious use.
