Scope Mount for AT-X with Nightforce C613: ATACR 7-35X56

No need for a 20MOA mount since the rail already has it built in.

1.5” height is easily your best bet. Anything lower and you’re going to be bottoming out your cheek rest/not able to get low enough for good eye relief.
 
I use a Spuhr SP-4302 on my AXMC. The rifle has a 30 MOA rail; the extra 3 MIL/10.6 MOA on the mount gets me within 10ish MOA of using the maximum travel of my ATACR 7-35 with a 100m zero (judging by actual remaining elevation travel, I could have gone with a 6 MIL mount, but that'd be cutting it too close IMO).

The height is a personal issue once you get beyond the obvious mechanical factors. I prefer to mount my scopes high because this works better with my eyeglasses.
