Guys - I like the Nikon Prostaff with BDC I put on my Genesis. It is very clear. I've only been out shooting once with it. Haven't had time to test the accuracy of the circles. But one neat thing, at 9X the circle surrounds a 1" dot at 100 yards. Which is nice when trying different loads. You use the crosshair for one group then the bottom circle for another. This prints the next group about a foot high.
