Thread: Do I. Don't I?

Why do you need two sets of inserts? The inserts do not show MOA. They are +/- inches I think. The actual MOA depends on the distance between bases. To get the maximum amount put the -.10 on the bottom at the front and the +.10 at the top on the front. Put the +.10 at the bottom on the back and the -.10 at the top on the back.
If you do the maths you should be able to work out how many MOA it is. Not that it really matters how much you actually get.
With a 20MOA base only you will easily get to 1000yds and stay in the middle part of the adjustment range.
