Diamondback DB15 Copperhead 223 Wylde 18" 30-Round Semi-Auto Rifle

The Diamondback DB15 Copperhead is a semi-automatic AR-15 rifle chambered in 223 Wylde, a chambering that is designed to safely handle both .223 Remington and 5.56x45mm NATO ammunition. It features an 18-inch heavy-profile 4150 CrMoV barrel with a black nitride finish and a 1:7 twist rate, fed by a rifle-length direct impingement gas system. The upper and lower receivers are forged 7075 T-6 aluminum, and the barrel and receiver set carry a Copperhead Cerakote finish.

The rifle includes a 15-inch M-LOK anti-rotation handguard with full-length Picatinny rails, a CMC 3.5 lb single-stage trigger, and a Magpul CTR carbine stock with an MOE K2 grip. The 1/2x28 threaded muzzle accepts the included CNC 17-4 stainless muzzle brake. The rifle ships without sights and is optics ready, with a 30-round capacity and AR-15 mil-spec fit.
