Abstract:
1. A fiber optic sighting device for use in ambient light and in darkness and comprising: (a) a sight base; (b) a fiber optic rod mounted in said sight base and having a proximal end and a distal end, wherein said distal end is cut at an angle to the longitudinal axis of said fiber optic rod, wherein said angled cut is positioned on the underside of the rod; and (c) a concentric cavity positioned in said fiber optic rod, wherein said concentric cavity is filled with a light source, said concentric cavity being sealed by a plug of fiber optic rod, and wherein said fiber optic rod is exposed to said ambient light, wherein said ambient light is directed through said fiber optic rod onto said angled cut; and whereby said ambient light is reflected along the major axis of said fiber optic rod, whereby said light source blocks said ambient light being reflected along said major axis of said fiber optic rod, excepting said ambient light being reflected around said light source and whereby said reflected light is then emitted from said proximal end of said fiber optic rod as a ring of light, and (d) in the absence of ambient light and in darkness, said light source directs light along the major axis of the rod directly toward its proximal end.
