The Diamondback Firearms DB15 .350 Legend 16" black rifle is a modern, efficient AR-platform carbine built around Winchester's popular intermediate cartridge. If you're looking for a .350 Legend rifle that delivers practical range and power without excessive recoil—whether for hunting medium game, training, or general shooting—the DB15 offers solid construction at a competitive level. The .350 Legend cartridge has carved out a loyal following among hunters who appreciate its ballistics in subsonic and standard loads, and this Diamondback platform delivers a reliable platform to shoot it.

The rifle combines a cold-hammer-forged 7075 T-6 aluminum upper and lower receiver with a 16-inch Diamondback barrel (4150 CrMov, black nitride finish, 1:8 twist) and carbine-length gas system—a time-tested configuration that balances handling and velocity. The mil-spec bolt carrier group is shot-peened and magnetic particle inspected to standard. A 15-inch M-LOK rail gives you solid real estate for mounting optics, lights, or other accessories, and textured pads on the handguard help maintain your grip in rough conditions. The MOE grip and MOE carbine stock are familiar, proven controls; the stock collapses to 32.5 inches or extends to 35.75 inches to fit different shooters and shooting positions.

At 6.6 pounds with stock collapsed, the DB15 is manageable for all-day hunting or range sessions. The A2 flash hider (1/2 x 28 threads) tames muzzle blast, and the rifle ships with a 5-round magazine—appropriate for the .350 Legend's intended use. A mil-spec trigger breaks predictably. This is no-frills, no-hype construction: a working rifle for hunters and shooters who appreciate straightforward AR-platform reliability in a hunting-appropriate caliber.
