Abstract: A rear peep sight (10) for use with a bow (100) having a bowstring (102), is described. The sight has a body (12) with a sighting member (14) extending upward and outward from a first surface (12F) of the body and an aligning post (22) extending upward and outward from a second surface (12G). The sight has grooves (12E) between the first and second surfaces to allow for mounting between the strings (104) of the bowstring. A sight opening (16) is located in the sighting member such as to be completely spaced beyond the body of the sight and the bowstring. The opening has a gap (18) along one side of the sighting member to allow additional light to enter the opening. The aligning post is connected to a tether (24) which is connected at the other end to the bow or cable (108). When the bowstring is moved into the fully drawn position, the tether becomes taut and moves the sight into the aligned position.
