Diamondback Firearms Db15 5.56 16" 10-Round Rifle

The Diamondback Firearms DB15 5.56 16" rifle delivers law enforcement and civilian shooters a purpose-built modern sporting rifle chambered in the proven 5.56 NATO cartridge. Built around a 16-inch barrel, this platform balances maneuverability and velocity for tactical applications, home defense, and precision target work. Weighing 7.94 pounds, the DB15 remains light enough for extended carry operations while maintaining inherent accuracy and ergonomic control—making it suitable for everything from duty use to recreational marksmanship.

The platform features a 12-inch M-Lok accessory rail system, allowing shooters to configure the rifle with modern optics, lights, and tactical accessories without rail clutter or weight penalty. The 10-round magazine capacity complies with restricted jurisdictions while maintaining reliable feeding and extraction in standard AR-15 pattern magazines. The compact 16-inch barrel length—a law enforcement and military standard—provides optimal velocity for 5.56 rounds while keeping overall dimensions manageable (39.2 inches) for vehicle storage, tactical entries, and close-quarters operations. This configuration is inherently accurate and requires no permanent modifications for most shooting scenarios.

Law enforcement agencies, security professionals, and civilian shooters seeking a reliable, configurable 5.56 rifle will find the Diamondback Firearms DB15 compatible with standard AR-15 furniture, slings, and optic mounts. The M-Lok rail accepts industry-standard accessories, enabling customization to match mission requirements or personal preferences. Drop-in installation of most aftermarket components is straightforward, and the rifle's modular design allows field maintenance and part replacement without gunsmithing expertise.
