Diamondback DB1784K131 DB15 5.56 NATO 30rd 16" Black Nitride w/ FDE Cerakote Flat Dark Earth Cerakote 7075-T6 Aluminum Receiver Flat Dark Earth Magpul MOE K2 FDE Grip

The Diamondback DB15 5.56 NATO rifle delivers a versatile, modern AR platform built for hunters, sport shooters, and tactical enthusiasts who want quality construction without compromise. This 16-inch carbine pairs a mid-length direct impingement system with a proven Mil-Spec design, making it equally at home on the range, in the field, or as a dependable home-defense rifle. The two-tone Flat Dark Earth Cerakote finish over a black nitride barrel gives it understated durability and a professional look that works across different environments.

The DB15 starts with a solid foundation: forged 7075-T6 aluminum upper and lower receivers, a shot-peened and magnetic particle inspected Mil-Spec BCG, and a 16-inch 4150 CrMoV barrel with a 1:8 twist rate and mid-length gas system. That combination handles 5.56 NATO ammo reliably while keeping recoil manageable for follow-up shots. The 15-inch M-LOK handguard with integrated full Picatinny rail and QD mounts gives you multiple attachment points for lights, optics, or vertical grips without the weight penalty of a full quad rail.

Ergonomics matter on a rifle you'll shoot frequently, and Diamondback equipped this gun with Magpul furniture: the MOE K2 grip in FDE for control and comfort, the CTR carbine stock in matching FDE for a solid cheek weld and adjustment range, and an enhanced trigger guard that plays well with gloved hands. The included 30-round Magpul Gen M3 PMAG in Coyote Tan rounds out a cohesive, functional package. No iron sights are installed, so you can zero in your optic of choice from day one. At 6.60 pounds, the DB15 is nimble enough for extended shooting sessions without sacrificing the heft needed for precision work.

Whether you're setting up a duty rifle, a hunting platform, or a training gun, the DB15 offers the modularity, reliability, and fit-and-finish you'd expect from a purpose-built AR without the guesswork of piecing together parts yourself.

Frequently Asked Questions

What optic or sight setup does the DB15 support?

The DB15 comes without iron sights and features a flat-top A3 upper receiver ready for any standard AR-pattern optic mount. You can use a Picatinny riser, red dot, low-power variable scope, or magnified optic of your choice. The integrated Picatinny rail on the handguard also accommodates lights and other accessories.

Is the DB15 suitable for hunting?

Yes. The 5.56 NATO chambering, 16-inch barrel, and mid-length gas system make it a practical rifle for hunting applications where that caliber is legal and appropriate. The modular design lets you customize it with optics, lights, and slings to match your hunting scenario, and the 30-round magazine capacity provides flexibility for various situations.

Can I swap out the Magpul furniture?

Absolutely. The Magpul MOE K2 grip, CTR stock, and other components are industry-standard AR-pattern parts. You can replace them with any compatible alternatives that suit your preferences. The M-LOK handguard accepts a wide range of aftermarket grips, rail sections, and accessories.

What comes in the box?

The DB15 is a complete rifle with a Magpul Gen M3 30-round PMAG in Coyote Tan included. No iron sights or optics are included, so you'll need to add an optic mounting system to get it on target. The DB Obsidian muzzle brake is already installed.
