A rear peep sight for use with an archery bow comprising:

• a sighting body having spaced apart, generally parallel and planar front and rear surfaces joined by a side surface, a cavity formed in said sighting body open to said sighting body front surface and having a bottom surface, a mounting groove formed in said sighting body side surface for retaining said sighting body on a bowstring and having a bottom surface, a sighting aperture formed in said sighting body extending from said sighting body rear surface to said cavity bottom surface and a plurality of locator apertures formed in said sighting body equidistant from said sighting aperture and extending from said sighting body rear surface to said cavity bottom surface;
• an insert body having front and rear surfaces joined by a side surface and being removably retained in said sighting body cavity, said insert body rear surface facing said cavity bottom surface and overlapping said locator apertures, said insert body being formed of a predetermined color light transmitting material for transmitting light incident on said insert body front surface to said insert body rear surface;
• and means for causing a portion of a bowstring to block removal of said insert body from said sighting body when said sighting body is mounted on the bowstring with said insert body located in said sighting body cavity and with a portion of said bowstring inserted into said mounting groove whereby when said sighting body with said insert body located therein is mounted on a bowstring light incident on said insert body front surface is transmitted through said insert body to said locator apertures and to an eye of an archer located at said sighting body rear surface.
