Ring height question for BAT action

[.257]

Looking for some help.

My br rifle should be ready any day. I am running a BAT MB action with 20 moa pic rail with a Kreiger HV contour barrel. I have a 56mm Nightforce standing by.

Any of you guys running a similar setup? Any idea on the lowest possible ring height that will work?

Oh I'm running a Tracker 1000 stock

since I don't have the rifle I have no way to get any measurments

Thanks
