  • Patent number: 4362145
    Abstract: A practice device which allows the simulation of firing of a weapon such as a light antitank weapon wherein the weapon can be fired in an armory for practice by soldiers without requiring the actual tactical missile to be fired which requires a large firing range with extreme protection of personnel. The invention comprises attaching a gas powered pellet gun within the barrel of the missile launcher and loading such pellet gun with a round of ammunition after which the gun is cocked and the weapon is sighted toward a target provided therefore and the pellet gun is fired with a suitable trigger for simulating and practicing actual use of the weapon. When the trigger is depressed it causes a solenoid to be momentarily energized, which draws a sear away from a firing cylinder causing actuation of a valve to fire the pellet gun.
