Diamondback Firearms DB1916B101 DB15 300 10" 31-Round Cerakote Pistol

The Diamondback Firearms DB1916B101 DB15 300 10" 31-Round Cerakote Pistol is a modern direct-impingement platform designed for shooters who demand a compact, high-capacity centerfire system. With a 10-inch barrel and 31-round capacity, this pistol excels in close-quarters environments where maneuverability and firepower matter—making it popular with tactical professionals, competition shooters, and home-defense advocates. The DB15 platform bridges the gap between traditional rifle ergonomics and pistol-length portability, delivering carbine-like controls in a legally compliant pistol format.

Built on proven direct-impingement principles, the DB15 300 operates with a conventional piston-less gas tube system that has proven reliability across millions of rounds in military and law enforcement service. The 10-inch barrel provides optimal velocity and dwell time for .300 Blackout ammunition while maintaining a compact overall length ideal for vehicle mounting, breaching, or single-handed transitions. Cerakote finish on the receiver and components provides superior corrosion resistance and durability compared to standard anodizing, crucial for field environments where salt spray, moisture, and temperature extremes demand long-term protection. At 7.25 lbs fully assembled, the system balances handling characteristics with the inherent weight needed for recoil management and sustained fire accuracy.

Law enforcement tactical teams, military personnel, and civilian shooters leveraging pistol-caliber-equivalent platforms will find the DB15 300 compatible with standard AR-15 upper receiver groups and lower receivers meeting federal guidelines. The 31-round magazine capacity and 10-inch barrel configuration make this platform particularly effective for vehicle-mounted applications, home-defense staging, and competition environments where rapid follow-up shots are essential. Proper eye protection and hearing protection are non-negotiable when operating this system, and shooters should verify all local and federal regulations regarding barrel length, overall length, and ammunition legality before purchase and deployment.
