A range finding bow sight for archery bows which includes a frame on which are mounted upper and lower mirrors in a substantially parallel relationship at a 45 degree angle and vertically aligned with each other forwardly of the bow. The top mirror is pivotally mounted and adjustably responsive to manipulation of a lever which cooperates through a programmed cam segment on a rotationally mounted sighting plate to which is attached a sight pin. Movement of the actuating lever correspondingly shifts the upper mirror to permit alignment of the actual target image with a reflected target image from the lower mirror. Movement of the actuating lever simultaneously positions the sight pin to provide the necessary elevation of the bow for the proper trajectory of the arrow to the target. The programmed cam section is removable and can be shaped to match the performance characteristics of the archery equipment being used.
