Brad, they will or can come with either Mil or MOA depending which scope and reticle !
I just had one made a couple weeks ago for the 6x6.8 with the yardage, It is one turn with zero stop and goes to about 750 yds for this rifle, i shot it from 100 to 700 yds and it was SPOT ON! (3x9 Mark AR Mod 1 with mil reticle) I try and do things the easy way if possible and for a hunting rifle that shots are not going to be that long.
I use the G1 BCs with a avg of 20 shots at the elevation that is pretty close to what all the areas will be that i will hunt with this rifle and use a Avg temp of 59 degs... I'am going to have 2 more done shortly so we will see i guess.
