The drop from a 100 yd zero is 20-25 moa, so you'll need at least 50 moa of adjustment range (60 moa is more likely), depending on how your rifle is built.
ran the numbers here on the lrh calc. it is 20 moa drop, 4.6 moa wind @ 5mph, and the bullet will go trans sonic round 550yrds. this was at an estimated mv of 2350fps. should be higher wen i reload, and factor in the barrel length, but was a modest estimate for sort of minimum ballistics i believe i could achieve
this will be shot out of an 18.5" barreled cz carbine not a 16" AK. more precise, and longer barrel.
want to keep the thing as light as possible, so was really giving thought to either the leupy Vx-II 1-4x or the VX-II ultralight 2-7x. they are within .3oz. of each other, anyone got any experience with either of those?
