Key specifications

The DIAMONDBACK DB15 is a semi-automatic rifle manufactured and imported by Diamond Back. Chambered in .223 / 5.56 NATO, it features a single 16″ barrel and a black finish. The rifle ships used with one magazine (30–39 capacity) and no case. At a price of $599.99, it offers a cost-conscious entry point into a proven platform.

Why the .223 / 5.56 NATO matters

The .223 / 5.56 NATO chambering provides low to moderate recoil, excellent ammo availability, and sufficient terminal performance for defensive scenarios when used with appropriate loads. For range work, .223/5.56 keeps ammo costs reasonable and allows fast follow-up shots—an important consideration for training and marksmanship development.

Ergonomics, barrel, and magazines

The 16″ single barrel delivers a good compromise between maneuverability and ballistic performance; it retains velocity for practical distances while keeping the overall rifle length manageable indoors. The included 30–39 round magazine capacity is standard for this class and supports sustained drills. Note the listing specifies a single magazine and no case, which factors into accessory planning.

Operational considerations

Being a used-condition rifle, inspect bolt-face, gas system, and barrel throat for wear when you receive it. The DB15’s familiar controls make accessories and optics swaps straightforward—run a quality optic on a flat-top receiver, and the DB15 becomes a versatile defensive or training rifle. Its black finish reduces glare and provides a practical, low-profile aesthetic.
