Mossberg S100, Micro Click Rear Sight, 1/8 Minute Adjustable Windage and Elevation

Good overall condition with some finish loss, stamped metal and forgings.  Accurate 1/8 minute click adjustable, one of the better sights available considering the engineering to produce a 1/8 minute adjustment.  (Never had the rifle to compare with my Redfield International Match)   Check the photos, mailing anywhere for $20.
