A detachable mount for a rifle telescope sight includes front and rear clamp support bases configured for attachment to a rifle, the bases having in their lateral side walls a plurality of detents arranged to receive the rounded ends of mounting screws extending through laterally spaced legs on front and rear scope clamp members configured for mounting on a telescope sight. The plurality of detents on the front base are arranged on a common axis that extends parallel to the longitudinal axis of the rifle barrel, and the plurality of detents on the rear base are arranged on a common axis that extends obliquely with respect to the axis of the front base detents, whereby to enable adjustment of the longitudinal axis of the telescope sight vertically relative to the rifle barrel. The spacing between the detents on the front base is different from the spacing between the detents on the rear base, whereby to ensure that a removed telescope sight must be returned to the same detents from which it had been removed. In a second embodiment, the obliguely arranged detents are replaced with a single detent in each end of a cam shaft mounted rotatably on the rear base for movement of the detent vertically across the common axis of the detents on the first base. A set screw releasably secures the cam shaft in desired position of adjustment of the detents.
