Abstract
A three-in-one high-pressure gas cylinder magazine. A high-pressure gas cylinder is installed within a holding cavity, and held firmly using a fine tuning knob and securing cover. A spring mount and a securing seat are disposed within a pellet guide cavity defined parallel to the holding cavity. When the pellets are decreasing, the inner securing seat upwardly pushes the pellets within the pellet guide cavity and secures them within a securing ring in a ready state for propelling out a model pistol. When a gastight valve within a cylinder is full of gas, then an inner piston rod is put in a pneumatic state, and the cylinder and a slide cover are simultaneously driven backward as soon as the piston rod is driven by the gas, thereby fixing a hammer in a rear position, thus achieving simplification, automatic operating functionality, and succeeding in simulating a real pistol.
