The Umarex 850 M2 powered by an 88 g CO₂ capsule resembles a traditional repeating rifle. A pellet is pushed into the rigid barrel with each cycle and a clean shot is fired, with no loss of energy. It offers a wide range of features: a ½"-20 UNF muzzle thread, up to three Picatinny rails, a removable additional cheek piece for shooting with a telescopic sight, a fiber-reinforced synthetic stock in a modern design and a high-quality aluminum magazine.
