The invention concerns an image-inverting system for a sighting telescope, where the image-inverting system has at least two lenses which are each held in a bearing with at least one tappet and are mutually displaceable parallel to an optical axis of the image-inverting system, where the displacement of the at least two displaceable lenses modifies a reproduction scale at which an image projected onto a first image plane of the image-inverting system is shown on a second image plane of the image-inverting system, and a guide rod with at least two curved guide channels, where the tappets engage in the guide channels, and at least a reinforcing ring which is arranged touching or affixed to the circumference of the guide rod for increasing the mechanical stability of the guide rod.
