The Diamondback Firearms DB15 Obsidian is an AR-15 style pistol chambered in .300 Blackout, with a 10-inch barrel and black finish. It comes with a pistol brace, which helps with stability when firing. The .300 Blackout was designed to work well from short barrels, so a 10-inch barrel makes good use of the cartridge. It is popular for home defense, ranch and truck use, and range shooting. As a pistol, it is subject to local and state laws, so check your regulations before you order.
