The invention provides a unique rifle scope detent mechanism, and rifle scope including such a detent mechanism, for adjusting elevation and windage of a rifle. The detent mechanism includes a convex spring with a detent ridge, that cooperates with grooves formed on a frontal face of a jack nut. Accordingly, as the jack nut is rotated during adjustment of the rifle scope, grooves of the jack nut click in and out of ridges of the spring. The jack nut is threadingly coupled to a jack screw that reciprocates as the nut rotates, thereby urging against an inner tube of the rifle scope that contains optics to adjust the rifle for elevation or windage.
