Abstract: A peep sight having a body with a sighting bore therethrough. The body receives a bow string and is connected by an elastic cord to the bow. When the bow string is in a drawn position the sight bore in the body of the peep sight is substantially horizontal. When the bow string is in a relaxed condition the bore is in an angled position with the longitudinal extension of the bow string. An elastic cord, such as a piece of flexible tubing, has one end fitted onto a pin extending from the body of the peep sight and a second end fitted onto a block which itself is adapted to be secured to an archery bow. As the bow string is drawn upon mounting of the body on the bow string and securing of the block to the archery bow, the elastic cord stretches to exert a force upon the body to align a sighting bore or "peep" therethrough with a bow-mounted bow sight.
