A small arms firing effects simulator utilizes a modular construction to egrate with the magazine of a weapon such as a rifle. The modular design resembles the ammunition clip and houses an expendable plastic coated plurality of pyrotechnic charges. An electrical control circuit is also housed within the module and serves to interface the pyrotechnic charges with the firing of the weapon, including semi-automatic and automatic firing as well as disabling the weapon when all rounds have been fired.

A laser diode optical system includes a laser diode having non-circular beam emitted from a diode emitter junction and having a peak energy centered on an optical axis, a collimating lens spaced from the laser diode with its focus at the laser diode on the optical axis to intercept direct energy from the laser diode and produce a central collimated beam on the optical axis, a paraboloidal reflector coaxially disposed about the laser diode emitted beam and collimating the portion of the emitted beam outside the included angle subtended by the lens, the collimated energy from the reflector being refracted through the periphery of the collimating lens to direct the collimated energy from the reflector into a hollow convergent-divergent conical beam coaxial about the central beam, a plurality of spaced energy diffusing elements on a surface of the lens intercepting and diffusing direct laser diode energy impinging the lens, and also intercepting and diffusing energy from the reflector, producing a spaced pattern of overlapping diffused beams forming a generally toroidal beam coaxially disposed about the central beam.
