As long as it has a 30mm Tube Diameter it can fit on there.
Not sure. Because the bases are part of the rings. I normally install bases then buy med rings for up to 44mm objectives.
I installed weaver bases and high Vortex rings for a rimfire rifle. SAV 93r the scope installed has a 50mm Obj lens and I have 1/4 in of space between the “bell” and the barrel. I wish it were only 1/8. But it’s fine. So you may have to roll the dice. Or get both Med and High so you have them both in hand. And return the ones that are not keeping the scope center axis as low as possible without making contact with the barrel
Good luck!!!!
