The Diamondback Firearms DB15 AR Pistol is a semi-automatic pistol chambered for .223 Remington and 5.56 NATO. It has a 10-inch threaded barrel, a 30+1 capacity and a Flat Dark Earth finish. The polymer grip and carbine-length direct-impingement system sit under a full-length Picatinny top rail for optics. The item is listed as new.

A Montana owner who wants a compact AR-15 pattern pistol for range use gets a short barrel with a carbine-length gas system. The 1/2x28 muzzle accepts compatible muzzle devices, and the rail takes a red dot or similar optic. The pistol is compatible with standard AR-15 pattern magazines, so the capacity follows the magazine the owner chooses. The threaded muzzle and full-length top rail let the owner change the setup over time without replacing the pistol.
