Abstract: Apparatus for the simulated shooting of small arms comprises a miniaturized electrical energy source for a radiation emitter which is capable of being accommodated within a dummy cartridge or within the gun barrel. The source can be a capacitor slidably located within the dummy cartridge and which co-operates with a barrel unit housing a switch section, an electronics section, and a pulsed infra-red emitter. On firing the gun the capacitor is propelled forwards by the firing pin of the gun until a probe-like switch portion on the capacitor contacts a corresponding switch portion on the barrel unit so actuating the emitter to give a series of timed pulses which pass through a lens system.

Abstract: A stunning gun in which a captive bolt is extended by an explosive cartridge detonated by a trigger controlled firing pin. The trigger is a push button device having a rounded surface and a shape and construction to avoid catching the finger of the gun operator. A piston on the trailing end of the bolt has a cupped recess in its end face to concentrate the explosive driving force and prevent it from spreading unduly to erode the firing chamber. A retaining collar acted on by a spring holds the bolt in its retracted position and releases the bolt when the gun is fired. A pull which is gripped to pull the firing pin to its cocked position is spring loaded to absorb forces applied to the end of the firing pin.
