If they are both round backs the base should fit.
The EGW bases are good and a lot cheaper.
The 1/2" ring would probably work with a 4-12x40.

Not sure if a low ring would fit.
I have more issues with the bell and front of the picatinny
rail clearance.
If you go on midway usa under rings there is a ring fitment guideline that might help you out.
