M700 with 20moa base and medium Palma contour barrel. Which height of Spuhr mount will I need. Barreled action is currently on a KRG Xray using vortex 35mm rings (can't remember what height) but it looks like they will be too low for the AIAX.
Not a Spuhr, but I am running Nightforce 1.375" rings on a Defiance with 30 MOA rail in an AX chassis with S&B 5-25x56. Plenty of room above the rail even with Butler Creeks. 1.4" will be more than enough.
