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—particularly valuable for home defense, law enforcement breaching teams, and civilian shooters prioritizing hearing protection.

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. At approximately one pound, this platform remains maneuverable in vehicle and confined-space operations without excessive weight penalty, making it genuinely practical for serious use.

This AR pistol is purpose-built for operators, security professionals, and dedicated civilian shooters who understand suppressed 300 Blackout ballistics and require a reliable, configurable platform for home defense or specialized training. The modular nature of the AR system means users can swap uppers, adjust optic mounts, and customize furniture to suit specific mission profiles—a capability that distinguishes this platform from fixed-configuration alternatives. Installation is straightforward for those familiar with AR assembly; the receiver group integrates with standard components, and the threaded barrel is ready to accept any 1/2x28 suppressor for enhanced hearing protection and tactical performance in real-world applications.
