ABSTRACT:
An improved combination of prism assembly and sighting target in a novel structure in which the sighting target provides a dual function by acting as the structural support for the prism assembly in addition to its usual function of providing a readily observable target from long distances. More specifically, the present invention provides, in a preferred embodiment, a diamond shaped sighting target, the center of which is provided with an aperture for receiving the prism assembly housing which extends therethrough in a direction normal to the plane of the sighting target. The prism housing is secured to the sighting target by means of a bracket into which the prism assembly is threaded, the bracket being secured to the sighting target.
