The Px4 Storm air pistol is not only a BB gun, but a pellet gun as well. It will shoot either projectile from its revolutionary dual-ended magazine. This 16-shot repeater will have you shooting as fast as you can pull the trigger. There's an 8-shot rotary clip on one end of the stick mag, and another one at the other end. Since it shoots BBs or pellets, you'll have more flexibility with ammo choice. A 12 g CO2 is easily loaded into the grip and gives you plenty of shots before you need a refill. There's even an accessory rail under the barrel. Like the handgun, it has real blowback action, it really kicks, giving you a feeling of power that most airguns only hope to achieve. Once you start shooting, you won't want to stop, so get lots of RWS pellets, BBs and Walther CO2. Features: Shoots BBs OR pellets Blowback action simulates real firearm Unique dual-ended 16-shot magazine Drop-free magazine adds realism Actually weighs the same as the firearm CO2 compartment in the grip Integrated accessory rail
