Correct scope rings for 56mm objective

[Bowhunter46]

What rings do I need for a 56mm objective? I have a Christensen arms Mesa and just ordered a Leica Ampulus 6 4-15x56. Was using leupold backcountry ring mounts and would like to go as low as possible

I used NF low but filed down the front boss on the rail.

This can somewhat depend on barrel profile and other factors, but I would be surprised if 1 inch was too low.
