ABSTRACT:
A rear peep sight for use with an archery bow has a sighting body with front and rear surfaces joined by a side surface and a mounting groove formed in the side surface for retaining the sighting body on a bowstring. A sighting aperture and a plurality of locator apertures extend from the rear surface to a bottom surface of a cavity in the sighting body. An insert body in the cavity is formed of a light transmitting material for transmitting light incident at the front surface through the locator apertures to an eye of an archer located at the rear surface. The insert body is removably retained in the cavity by the bowstring such that it can be replaced by an insert body of a different color. Shutters formed on the sighting body rear surface, opaque areas on the insert body and shutter apertures are utilized to vary the amount of transmitted light reaching the eye of the archer.
