ABSTRACT:
An accessory for converting a small bore firearm into a safe theatrical stage prop providing both aural effects of the "report" of detonated gunpowder and visual effects of discharged "gunsmoke" and "recoil" motion imparted to the body of a user, is constructed with a central passage 20 partially obstructed by a dimensionally conforming cylindrical mass 36. Effluent in the form of expanding gases of detonated gunpowder enter central passage 20 via proximal orifice 16, impart forward motion in a preferred direction to cylindrical mass 36 and, as movement of mass 36 exposes connecting passages 30, the effluent bypasses the central portion of passage 20 via passages 22 and exits the barrel 10 of the accessory via distal orifice 18. Motion imparted to mass 36 first by the expanding effluent and then in a reverse direction by compressed spring 40, simulates the visual effect of "recoil" upon detonation of a blank cartridge of ammunition.
