I have my Nightforce 1-4 in a 20MOA mount because all Nightforce Unimounts are 20MOA.
Regardless, zeroed at 100 or 200 yards it will put the scope close to mechanical center or even a little down. It really doesn't matter on a 1-4, but the mount may not always be for a 1-4. It just doesn't make sense to me to not use a canted base unless you're stacking NODs with your optic.
