Diamondback DB15 5.56 NATO Semi-Auto Rifle – 16″ Threaded Barrel, 10rd PMAG, M-LOK Handguard, Magpul Stock & Grip

The Diamondback DB15 is a precision-built, California-compliant AR-15 platform rifle chambered in 5.56 NATO, designed for shooters who demand reliable performance and premium components at a competitive price point.

Built on a forged 7075 T-6 aluminum upper and lower receiver set, the DB15 features Diamondback’s own 16-inch, 4150 CrMoV steel barrel with a 1:8 right-hand twist and a durable black nitride finish — delivering consistent accuracy and long-term corrosion resistance. The carbine-length gas system pairs with a shot-peened, Magnetic Particle Inspected (MPI) Mil-Spec 8620 carrier bolt carrier group for reliable cycling and peace of mind.

The 15-inch M-LOK handguard provides a full-length attachment platform for lights, lasers, grips, and accessories, while Magpul’s MOE Carbine Stock and MOE Grip offer a comfortable, field-proven ergonomic package right out of the box. The rifle ships with a Magpul Gen M3 10-round PMAG and includes an AR Maglock Kit for compliance in restricted-capacity states.

The A2 flash hider threads onto a 1/2×28 muzzle thread pattern, keeping the door open for future suppressor or muzzle device upgrades. The A3 flat-top upper with T-markings accepts any standard Picatinny optics or iron sights, so you can tailor the build to your mission.
