Gas-powered pellet pistols are accurate and powerful at close range. They are popular with shooters everywhere for use in target practice, competition and vermin control. The CO2-filled gas cylinder of your weapon holds air that propels the BB or pellet toward your target when the trigger is pulled. The only problem is that the cylinder has to be replaced every couple of dozen shots. Changing cylinders in your gun is an easy process, though, as long as you follow the proper procedure.
Aim the weapon at the ground and pull the trigger to be sure there is no ammunition in the chamber. Activate the safety mechanism on the pistol.
Grasp the barrel of the gun with the opening pointing at the ground. Do not put any part of your body in front of the barrel of the pistol.
Twist the nut on the bottom of the grip counterclockwise until it stops. Be careful of escaping gas during this process.
Grab the bottom of the textured side of the pistol grip and pull it away from the pistol to remove the old cylinder from inside the handle. Pop the old cylinder out of the retaining clip and discard it.
Place a new cylinder into the clip. Slide the handle, cylinder first, back into the pistol grip. Twist the nut under the grip until it is snug, then give a quick quarter-turn to pop the seal on the new cylinder and seal the system.
