In accordance with conventional practice, the external grooves 15 permit mounting of the disc on the bowstring by separating the strands of the bowstring, inserting the disc between the strands and releasing the strands to move into snugfitting engagement against the inner surfaces 16 of the grooves. The body 10 preferably takes the form of a flat, generally circular disc, and the bowstring-receiving portion 12 is defined by external grooves 15 which are formed along diametrically opposite sides of the disc symmetrically with respect to a vertical center line extending along the plane of the disc. In addition, a recessed portion is formed out of the body of the disc concentrically with respect to the peripheral outline of the disc and which effectively defines a flared or divergent surface portion away from the sight opening proper both for the purpose of minimizing glare or reflection and of channeling the archers line of sight through the sight opening. By forming the opening on an axis disposed at a downwardly inclined angle of inclination away from a line normal to the disc, as described the effective opening size of the sight will be at its greatest when the sight is tipped upwardly into the line of sight of the archer and accordingly enables use of a smaller opening than if the opening were merely to extend on an axis normal to the plane of the disc and thus permits construction of a more compact disc. In this way, the axis of the sight opening will be drawn upwardly into the line of sight of the archer when the bowstring is drawn rearwardly to the cocked position. The axis of the sight opening extends along a downward angle of inclination with respect to a center line normal to the plane of the disc and is substantially equal to the angle of displacement of the bowstring away from vertical when the bowstring is drawn rearwardly to its cocked position. In its preferred form, the peep sight takes the form of a generally circular disc having external, bowstring-receiving grooves extending along opposite sides of the disc symmetrically with respect to the center line of the bowstring and a sight opening former in a central portion of reduced thickness intermediately between the external grooves. In accordance with the present invention, an archery peep sight has been devised which may take the form either of a generally circular or elliptical body molded or otherwise constructed out of a single piece of material to define a bowstring-receiving portion, a sight opening and a hood which forms a rearward projection of the body of the sight.
