ABSTRACT:
A reticle gunsight is illuminated by a chemical illumination stick which is nserted through a tapped port in a lower chamber of the gunsight. The tapped port is closed with a threaded plug to retain light within the lower chamber. The lower chamber has an optical opening therein which is aligned with reticle cross hairs to produce a light beam having the image of the cross hairs. The light beam is focussed through a collimated lens and then directed by a prism onto a beam splitter in an upper chamber of the reticle gunsight. The upper chamber is open at both ends and is aligned with the barrel of the gun so that when the image of the target is superimposed with the image of the reticle in the beam splitter, the person using the gun knows that the gun is aimed at the target. Since the gunsight does not rely on electrical illumination and does not itself illuminate the target, many deficiencies associated with previous gunsight configurations are eliminated.
