Diamondback Firearms DB1874K001 DB15 5.56 NATO 16" 31-Round Rifle

The Diamondback Firearms DB15 5.56 NATO 16" rifle represents a modern, reliable platform purpose-built for tactical operations, home defense, and precision shooting applications. This rifle is engineered for shooters who demand consistent accuracy and durability without unnecessary complexity. The DB15 platform has proven itself across law enforcement training scenarios and civilian tactical courses, delivering the performance standards required in high-stress environments.

Built on a traditional direct impingement operating system, the Diamondback DB15 cycles 5.56 NATO ammunition reliably through its 16-inch barrel—a length that balances muzzle velocity with maneuverability in confined spaces. The rifle ships with one 31-round magazine, providing substantial on-board capacity for extended engagements or training drills. At 13.4 lbs unloaded, the platform delivers a lightweight profile without sacrificing structural rigidity, allowing operators to maintain control during rapid fire or dynamic movement. The 47.6-inch overall length positions this rifle as a versatile option for vehicle storage, close-quarters tactical work, and standard shooting disciplines.

Law enforcement trainers and civilian tactical shooters will find the DB15 compatible with standard AR-15 furniture, optics mounting systems, and aftermarket accessories—a significant advantage for customization and shooting preference. The rifle's ergonomic design accommodates both right and left-handed shooters with standard controls, reducing transition time during training or operational deployment. Magazine compatibility with standard AR-15 platforms means shooters can leverage existing ammunition inventories and spare magazines without additional investment, streamlining logistics for active users and training operations.
