ABSTRACT:
A telescopic sight for a sharp shooting rifle has an inner tube with a main telescope outer tube formed with an objective lens system, which includes a variable magnification optical system. This optical system is controlled by a cam sleeve on the inner tube rotatable by a setting ring on the main tube. A lens of the variable magnification optical system is connected to an elongated cam which fits between an elevational setting screw on the main tube to adjust the angular position of the inner tube to set the elevation in accordance with the magnification and hence the distance to the target.
