The Diamondback Firearms DB15 Obsidian is an AR-15 style pistol chambered in .300 Blackout with a 10-inch barrel and a flat dark earth finish. It is fitted with a pistol brace, which makes it easier to control one-handed or against the forearm. The short barrel makes the .300 Blackout a good fit, since the cartridge was built to perform well from compact barrels. Compact AR pistols are popular for home defense, truck guns and general range use. As a pistol, it is subject to your state and local laws, so please check the rules where you live.
