Abstract: A peep sight which is rotatably mounted to the string of the bow and includes a generally cylindrical body having a lateral bore therethrough, at least one sighting member angularly mounted on the outer wall of the body, and a weighted member displaced at an angle (generally between 40-90 degrees), also mounted on the outer wall of the body and emanating from the body in a position generally perpendicular relative the sighting member. The present invention provides a peep sighting system wherein the sight is always parallel with the horizon, notwithstanding the angle of the bow. Further, the sight is always in the correct alignment with the aiming eye of the user, unlike prior art methods, which were rigidly affixed to the string, and thereby often did not align appropriately with the user and target at critical times.
