For sale, one as new DPMS brand detachable rear sight for flattop mounting platform on your AR. This is the one with two attachment screws, 800 meters of elevation adjust, along with standard A2 style windage adjustment. This is a nice quality sight. Sorry, forgot to update, this sight is SOLD
Would possibly trade for a Bushy or Colt brand A2 style detachable, flattop carry handle.
