Just a rough idea: You're going to need, depending on your load, roughly 30-40 moa up at 1000. The scope has 56. Say half of that is available(28) + the 25 moa rail = 53 moa. Yes, you'll have enough....and not much to spare. I'm surprised that the S&B only has 56 moa of elevation adjustment. Are you sure that's correct? My NXS has 100.
I think NXS has 110. Correct me if I am wrong
