Abstract:
1. An optical sight, comprising: a reference housing extending from a first side surface to a second side surface and having a reference housing aperture formed within the reference housing; a pillow block extending from a first side surface to a second side surface, wherein the pillow block is coupled to the reference housing; at least one reference point positioned within the reference housing aperture; an eclipsed ring extending from a first side surface to a second side surface and having an eclipsed ring aperture formed within the eclipsed ring; wherein the eclipsed ring includes a pivot aperture formed therein, wherein the eclipsed ring is pivotably coupled, via a pivot pin extending through the pivot aperture, to the pillow block such that the eclipsed ring may pivot relative to the reference housing and such that the eclipsed ring naturally pivots to a predetermined position, and wherein the eclipsed ring is pivotably coupled such that the first side surface of the eclipsed ring faces generally towards the second side surface of the reference housing; and at least one surface preparation on the first side surface of the eclipsed ring, wherein the surface preparation is visually distinguishable from a surface of the reference housing aperture formed within the reference housing; wherein the first side surface of the eclipsed ring is shaped such that when the reference housing and the eclipsed ring are aligned, the at least one surface preparation on the first side surface of the eclipsed ring is not visible through the reference housing aperture.
