Diamondback Firearms DB1718B002 DB15 300 31-Round Rifle

The Diamondback DB15 300 Blackout rifle delivers precision and modularity in a compact platform purpose-built for suppressed shooting, close-quarters engagement, and specialized tactical operations. Chambered in 300 AAC Blackout, this 16-inch barreled system excels in subsonic ammunition applications where hearing safety and sound signature reduction are mission-critical. Whether for law enforcement breaching operations, military designated marksman work, or advanced civilian tactical training, the DB15 provides the reliability and ergonomic control demanded by professionals who depend on their equipment under stress.

Built around a forged 7075 T-6 aluminum receiver with hardcoat black anodize finish, this rifle achieves an 8.4-pound fighting weight that balances ammunition capacity with rapid target transitions. The 15-inch M-LOK rail provides genuine modularity—allowing integration of tactical lights, lasers, vertical grips, and forward-mounted optics without compromise to ergonomics or sight radius. The 30+1 round capacity utilizes standard STANAG magazines, ensuring logistics simplicity and compatibility across platforms. Black synthetic furniture resists environmental corrosion and temperature fluctuation, critical factors in field applications where polymer stocks must maintain zero and ergonomic consistency across operational cycles.

This configuration suits shooters seeking a suppressed-ready rifle without integrated sights, allowing users to select optics matched to their mission profile—from low-power variable or red-dot systems to night-vision compatible platforms. The forged aluminum construction delivers superior dimensional stability compared to cast receivers, maintaining zero retention critical for precision work. Installation of a quality suppressor, bolt-carrier group optimized for 300 Blackout subsonic loads, and appropriate charging handle upgrade transforms the DB15 into a dedicated breaching or low-light platform. The 16-inch barrel optimizes 300 Blackout ballistics while maintaining portability in vehicle, building, or aircraft environments.
