Diamondback DB1718K001 DB15 5.56 NATO 30+1 16" Black Nitride Threaded Barrel, Black Hardcoat Anodize Picatinny Rail Aluminum Receiver, Adjustable Black Synthetic Stock, Magpul MOE Grip
The Diamondback DB15 5.56 NATO rifle is a mid-length gas system AR-pattern platform built for shooters who want a reliable, shooter-friendly carbine without unnecessary frills or inflated pricing. This 16-inch barrel rifle ships ready to run—you get 30+1 capacity, Magpul MOE furniture, and a full-featured rail system right out of the box, making it an excellent choice for range work, hunting, home defense, or training.
The core is honest engineering: a forged 7075 T-6 aluminum upper and lower receiver with black hardcoat anodize finish for durability. The 16-inch barrel is 4150 CrMov steel with black nitride coating and a 1:8 right-hand twist, threaded for a muzzle device. Diamondback equips it with a mil-spec shot-peened carrier that's been magnetic particle inspected—the kind of attention to bolt integrity that matters when you're depending on a rifle. You get a standard mil-spec trigger, an A2 5.56 flash hider, and the Magpul MOE adjustable stock and grip that have become the practical baseline for AR carbines.
The handguard deserves mention: a full 15-inch M-LOK rail with texture pads, picatinny mounted front and rear, QD sling points, and a hand stop. That's real estate for optics, lights, or rails without the weight penalty of quad-rail dinosaurs. At 6.7 pounds (collapsed), it's light enough for a day in the field but built stout enough for consistent use. The DB15 comes with a 30-round Magpul Gen M2 PMAG—a standard that works everywhere. Sights are not included, leaving you room to mount the optic system that fits your mission.
This is the kind of rifle that doesn't need to talk itself up. It shoots straight, runs clean, and costs less than it should.
