Diamondback's DB15 Obsidian is a Florida-built AR-15 with an upgraded look and feel, and this version is chambered in 6mm ARC, the cartridge Hornady designed in 2020 to give the AR-15 real long-range performance. From the 18-inch barrel, 6mm ARC drives 108-grain match bullets and 103-grain hunting bullets with far less drop and drift than 5.56, making it a legitimate 800-yard target rifle and a clean deer, antelope and coyote cartridge. The M-LOK handguard accepts lights, bipods and grips, and the OD Green finish sets it apart from the sea of black rifles. It runs standard AR-15 lowers and controls with a 6mm ARC bolt and magazines.
