med high rings will be more than enough, at a 44 MM objective, I have mounted a few 50's on med's Leopold bases and rings
Burris makes nice 30 Mm rings, just stuck them on a .223 with a 50 mm objective scope
most scopes will determine EYE relief and if you need rings to adjust for or not, all depends on where the scope's parts are hard mounted to them
, as they relate to how far you can slide the scope forward or backwards in the rings before they hit the windage/elevation knobs, or the scopes eye piece adjustment rings

NOT all scopes have the same amount of room for things, and that;'s why they also sell rings with different mountings to allow for them if needed
you will know real fast once you get them LOL if you have clearance or not<
