a 0 MOA 1.35" will work but will leave very little room for scope caps. Ran this on a pre-14 AX338 with 56mm objective SB for a while. However, having gone down this path, the 0 MOA 1.5" height mount is the correct option for this platform IMHO - I can shoot my 300NM AXMC out to 2400yds with that set up.
