Abstract
A toy gun includes a housing; a barrel extending forwardly of the housing; a motor in a pistol grip; a speed reduction gear in the housing and operatively connected to the motor; a bullet loading unit in a forward end of the housing; a spring biased piston in a fixed cylinder of the housing; a trigger for activating the motor for firing; and a backward momentum transferring mechanism partially disposed in a gunstock and including an intermediate weight, a forward sliding rod disposed rearward of the piston, and a rear recoil spring having a front end urging against a rear end of the weight and a rear end urging against an internal wall in the gunstock. The sliding rod is disposed in the housing and spaced apart from the weight. The backward momentum transferring mechanism can simulate recoil by generating a recoil shock.
