The DB15 Carbon Series pairs aluminum receivers in a matte black finish with Diamondback’s DB shield logo on the magwell. The lower is marked "CAL. MULTI" with "SAFE/FIRE" selector positions and uses a STANAG-pattern 30-round magazine interface. Controls include a right-side magazine release, a left-side bolt catch, and a manual, non-ambidextrous safety.
The 16-inch steel barrel is threaded and fitted with an A2-style birdcage flash hider. The rifle operates via a semi-automatic, direct impingement system and is chambered in 5.56mm NATO with a listed capacity of 30+1.
The free-float, approximately 15-inch aluminum M-LOK handguard provides mounting versatility, with short Picatinny sections at 6 o’clock and near the front top. A Picatinny accessory rail segment is already installed on the handguard, and the upper receiver features a continuous top rail.
The flat-top A3 upper includes a forward assist, case deflector, and a dust cover marked "5.56 / NATO." The rifle is set up with a 6-position collapsible polymer stock (black) that includes a sling loop, an A2-style polymer pistol grip, and a standard charging handle. Sights are not included.
Made in the USA, this DB15 was manufactured in Cocoa, Florida, and comes finished in a uniform matte black across the receivers and furniture. Length of pull is listed at 10.5 inches.
