Airgun
First Claim
1. An airgun of the type wherein a projectile is fired by compressed air from a chamber provided with a spring-operated piston, the improvement comprising a breech casing, a transport mechanism for compressing the piston spring, the transport mechanism including a worm, a nut mounted on the worm for longitudinal movement therealong with respect to the breech casing between forward and rearward positions, and a pusher catch mounted on the nut, an electric motor for driving the transport mechanism, a battery for powering the electric motor, and the transport mechanism, electric motor and battery being incorporated within the airgun.
