Diamondback Firearms DB1758K001 DB15 5.56 NATO 16" 31-Round Carbine

The Diamondback Firearms DB15 5.56 NATO 16" carbine is a purpose-built rifle designed for law enforcement patrol, home defense, and tactical training environments where reliability and ergonomic efficiency are essential. This platform meets the operational demands of professionals and serious civilian shooters who require a modern direct-impingement carbine capable of delivering consistent performance across high-round-count training cycles and duty deployment.

The 16-inch barrel strikes a proven balance between velocity retention, handling speed, and legal compliance across all 50 states. Built on the legacy AR-15 platform, the DB15 carbine features a cold-hammer-forged barrel chambered in 5.56 NATO, ensuring chamber consistency and extended barrel life under sustained fire. The magazine has a capacity of 30 rounds, providing sufficient ammunition reserve for extended engagement scenarios without frequent reloads, a critical consideration in defensive contexts.

At an unloaded weight of 13.2 lbs, the carbine maintains maneuverability in confined spaces typical of building searches and vehicle operations while remaining stable for precision shooting at intermediate distances. The compact overall profile makes this rifle ideal for operators transitioning between different tactical environments without sacrificing the velocity floor needed for terminal performance and barrier penetration. This DB15 carbine is optimized for duty personnel, whether reserve or full-time law enforcement.
