Your not getting it. I moved the sight all the way up to the top, it still shoots a atleast a foot high. So I moved back to 20 yards and i used the second pin, shot high still. So i used the very top pin and it shoots about 6 inches high with the pin all the way to the top from 20 yards. So i went back to 30 yards, and now the pin is about one centimeter from the top. What I need is for the individule sight to move atleast 3 maybe 4 inches from the bottom to the top. See the thing is 2 inches, but it needs to be like 4 or something.
