Diamondback Firearms DB1915K061 DB15 5.56 NATO 10" 31-Round Carbine

The Diamondback Firearms DB1915K061 DB15 5.56 NATO 10" 31-round carbine is purpose-built for tactical operators, law enforcement professionals, and civilian shooters who demand a compact, reliable platform without sacrificing firepower. The 10-inch barrel configuration delivers the maneuverability required for close-quarters operations, vehicle entry, and confined-space engagements while maintaining effective velocity and accuracy at combat distances. This short-stroke piston carbine addresses the operational gap between pistol-caliber platforms and full-size rifles, making it ideal for home defense, professional duty, and advanced tactical training environments.

Built on a proven direct impingement system, the DB15 achieves reliable cycling across the full spectrum of 5.56 NATO ammunition. The 31-round magazine capacity provides ample ammunition reserves for sustained engagement without constant reloads—critical in high-stress scenarios where split-second decisions matter. At 6.8 pounds unloaded, the carbine maintains a low center of gravity and quick target transitions, while the compact 31.6-inch overall length facilitates rapid movement through doorways, vehicles, and tight quarters. The 8.8-inch rail interface width supports multiple optic, laser, and accessory configurations, allowing shooters to customize the platform to mission-specific requirements with standard mil-spec components.

Professional end-users—from SWAT teams to private security—benefit from the DB15's rapid handling characteristics and proven 5.56 NATO ballistics, while experienced civilians value its modularity and straightforward maintenance. The carbine accepts standard AR-platform magazines, triggers, and bolt carrier groups, ensuring compatibility with the most common tactical aftermarket ecosystem. Field-proven in training and operational environments, the Diamondback DB15 delivers the reliability, accuracy, and ergonomics required when performance directly impacts safety and mission success.
