Diamondback DB1718K071 DB15 Carbon Series 5.56 NATO 30+1 16" Black Nitride Threaded Barrel, Midnight Bronze Cerakote Picatinny Rail Aluminum Receiver, Adjustable Black Synthetic Stock, Magpul MOE Grip

The Diamondback DB15 Carbon Series 5.56 NATO rifle is a mid-length gas system AR-15 built on a forged 7075 T-6 aluminum receiver with a midnight bronze Cerakote finish—a modern platform that balances accuracy, reliability, and shootability for hunters, sport shooters, and tactical competitors. The 16-inch barrel is 4150 CrMov steel with black nitride finish and a 1:8 right-hand twist rate that handles the full range of 5.56 NATO and .223 Remington loads. With a 30-round magazine capacity and an A2 flash hider, this is a versatile carbine for everything from 3-gun matches to medium-range hunting and home defense.

This rifle ships with genuine Magpul components throughout: the MOE grip, adjustable MOE PR carbine stock (collapsible from 32.75 inches to 36 inches), and a 30-round Gen M2 PMag. The 15-inch m-LOK handguard features full top Picatinny rail, rear Picatinny mounting, integrated QD points, and textured panels for reliable grip in all conditions. The bolt carrier group is shot-peened and magnetic particle inspected mil-spec 8620 steel—the kind of quality control you expect from a rifle that has to run.

At 6.7 pounds, the DB15 Carbon is light enough for a day in the field but substantial enough to manage recoil and hold steady on steel. The flat-top upper receiver is forged and T-marked, ready to accept any optic mount. The mid-length gas system and standard mil-spec trigger are proven patterns that have stood the test of time in service rifles and competition rigs alike. No sights are included—plan for a quality red dot, LPVO, or traditional iron setup.

Whether you're building your first centerfire rifle or adding to an existing battery, the DB15 Carbon delivers Diamondback's reputation for value and reliability without unnecessary marketing fluff.
