ABSTRACT:
Disclosed is a gun sight elevation adjusting apparatus having an adjusting screw threaded into the sight elevation body for adjusting the elevation of the sight. The screw has an annular groove and a plurality of circumferentially spaced indentations thereabout below the groove. A generally U-shaped clip is retained on the screw as its legs straddle the screw about the groove. A tang is bent out of the plane of the clip and its point rides on the screw to engage in the indentations upon rotation of the screw and registration of the indentations with the tip. The clip prevents the screw from being removed from the sight body and provides an audible click to click and a positive snap-like feel adjustment for the sight.
