Diamondback Firearms Db15 5.56 16" 30-Round Rifle

The Diamondback Firearms DB15 5.56 16" rifle represents a proven mid-length platform trusted by law enforcement and civilian shooters alike for duty, training, and home defense applications. Built on the AR-15 operating system, this semi-automatic rifle combines the versatility of 5.56 NATO/.223 Remington caliber with a compact 16-inch barrel that balances maneuverability and velocity in confined spaces. The 30-round magazine capacity delivers practical firepower for extended engagements while maintaining faster reload discipline compared to smaller magazine configurations.

The DB15 incorporates M-LOK rail integration across the handguard, enabling rapid mounting of tactical accessories—lights, lasers, optics, and grips—without the need for rail covers or adapters. The 16-inch barrel length optimizes sight radius for accurate target engagement while keeping overall rifle length under 37 inches when shouldered, critical for vehicle egress and tight quarters work. At 7.88 pounds unloaded, the rifle maintains a manageable weight for prolonged carry and precision shooting, with the semi-automatic operation and direct impingement system ensuring reliable function across temperature extremes and duty cycles.

This rifle suits law enforcement carbine courses, tactical training environments, and civilian home-defense scenarios where intermediate-range precision and rapid follow-up shots are essential. The modular M-LOK design allows users to configure the platform for specific mission requirements—from minimalist setups to fully accessorized duty rifles. Standard AR-15 upper and lower receiver compatibility ensures unrestricted parts availability, making the DB15 an excellent platform for shooters seeking long-term customization and upgradeability without factory limitations.
