Diamondback Obsidian DB15 6mm Arc 18 inch 26 Round Magpul Carbine Stock Rifle

The Diamondback Obsidian DB15 AR Rifle in Black brings the Obsidian series' balance of modern AR ergonomics and 6mm ARC performance to shooters who demand mid- to long-range capability from a lightweight, serviceable platform. Built on forged 7075 T-6 aluminum upper and lower receivers with a Magpul CTR carbine stock and MOE K2 grip, this 18" 4150 CrMoV medium-taper barrel with a 1:7.5 RH twist and black nitride treatment is optimized for stabilized 6mm projectiles, making it suitable for hunting, precision target work, and tactical training. The mid-length direct-impingement gas system and a shot-peened, magnetic particle inspected Mil-Spec 8620 carrier BCG promote smooth recoil impulse and reliable cycling, while the 15" M-LOK anti-rotation S-rail with full Picatinny and QD mounts provides ample attachment real estate for optics, lights, and bipods without adding excessive weight. The DB Obsidian muzzle brake (5/8x24) tames muzzle rise, the standard Mil-Spec trigger offers familiar control, and a 26-round metal magazine capacity supports extended range sessions; an FFL transfer is required for purchase. If you're looking for a versatile AR in 6mm ARC that balances duty-grade materials, shooter-friendly ergonomics, and caliber performance, the DB15 is a compelling option.
