An archery bow sight has a sight tube which is fixed to a link arm which extends between two rotatable members mounted to a frame which is connected to the riser of a bow. The arm is pinned to the rear rotatable member at a radius which is less than the radius at which it is pinned to the front rotatable member. The rotation of the rotatable members is synchronized by a connector such as an intermediate gear, a timing belt, a rigid link, or a linked chain. By rotation of a range adjustment knob, the sight tube is caused to change simultaneously in inclination and in height in such a way that the archer may continue to view the target through the sight tube. The sight tube has a fiber optic sight point. The relationship between the rotating members and the link arm is adjustable for draw length.
