The CO2-powered 850 M2 resembles a traditional repeating rifle. A pellet is pushed into the rigid barrel with each cycle of its bolt, and a clean shot is fired with no loss of energy. It offers a wide range of features, including Picatinny rails, a removable cheekpiece, a fiber-reinforced synthetic stock, fiber-optic sights, a two-stage adjustable trigger, an 11mm scope mounting rail, and an aluminum eight-round magazine. It can shoot as many as 200 shots with one 88-gram CO2 cartridge, and sends pellets up to 760 fps. SRP: $299.99.
