The BRN-10 uses the same rear sight wheel as an M16A2, but instead of reading the range from the side, it's read from the rear.

Not very easy to see.  I wonder how hard it would be to get it out and color fill the numbers to be more visible.

You can also see the little screw that locks the windage for zeroing it between the range window and rear aperture.
