The Nightforce has a mounting length of 5.1" vs a Leupold 2.5-8 at 5.2". I also have the Leupold mounted on my .375 in Tally QD mounts and as you can see there is zero room for ER adjustment but thanks to it's forgiving eyebox it works.
I originally bought it with the same scope but in Leupold windage adjustable bases and there was plenty of room for fore and aft adjustment. If you're interested in these bases let me know
