The DB15 is a direct-impingement AR-15 pattern rifle built around a 16 inch barrel and a threaded muzzle capped with a three-prong flash-hider–style device. It accepts detachable AR-15 pattern magazines and is chambered for 5.56mm NATO.
The flat-top upper receiver provides a Picatinny rail for mounting sights or accessories and includes a forward assist and shell deflector. The ejection port dust cover is stenciled "5.56 NATO," while the lower is marked "CAL. MULTI."
A free-float aluminum M-LOK handguard with the Diamondback DB shield logo offers modern accessory mounting options. The rifle also includes a manual safety with clear SAFE/FIRE markings.
Furniture is finished in black, with a 6-position collapsible stock and an A2-style polymer pistol grip. The two-tone appearance of green receivers with black handguard and stock gives this DB15 a distinctive, purpose-built look, and the included S60 magazine delivers extended 60+1 capacity.
