I'm having good luck with my new Leupold EFR 3-9 with BKL-260D7 4" Long Drop Compensated Dovetail Mount. The new Leupold EFR have very good glass with fine reticle, short enough to allow good access for loading. I did half to sand of some material at the center of the scope mount to clear the scope.
Not sure about the rings. They are what I had in my toolbox. They have quick release levers, 30MM. standard height and fit Picatinny rails.. I might have gotten these with a UTG scope that I bought. From the picture, I think the medium height UTG/Leapers rings are wihat I used.
