The Diamondback Obsidian DB15 is an AR-15-pattern semi-automatic rifle chambered in 5.56 NATO/.223 Remington with a 16-inch barrel. The Obsidian line is Diamondback's modern-styled offering, and this version wears an OD green finish with an M-LOK handguard for easy attachment of lights, grips, and accessories.

With a 16-inch barrel it is a classic carbine size for home defense, range work, and general-purpose use. Diamondback has built a reputation for dependable, reasonably priced AR-pattern rifles, and the AR platform's huge aftermarket means you can customize optics, stocks, and triggers however you like.
