Abstract

The invention relates to a composite electromagnetic sniper rifle, which comprises a gun body, a main magazine, an auxiliary magazine, a switching knob, a bracket, a sight, a pull bolt and the like. The composite firing mechanism is located in the gun body; the main magazine is located in the front of the trigger, which is composed of a capacitor and a magazine; the auxiliary magazine is located in the handle. There is a mode switch knob on the side of the gun body above the handle. There is a scope on the top of the gun body. When the knob is in mode 1, it is in the electromagnetic launch state, and the bullet enters the pre-launch track from the main magazine; when the knob is rotated to make it in mode 2, it is in the mechanical launch state, and the bullet enters the pre-launch track from the auxiliary magazine. Compared with mechanical launch, the electromagnetic launch system increases the number of ammunition, reduces the risk of sound, fire, and smoke easily exposing the sniper's position from mechanical launch, and enhances concealment; it also makes up for the initial launch of bullets during long-distance shooting with pure electromagnetic launch. Insufficient speed defect.
