Like many have said, I wouldn't go any larger than a 40mm or a 44mm objective for your scope. You would probably have to go with larger rings on a scope that is larger. It's not a terrible thing, but the higher your scope is off your gun the greater chance you have of knocking it out of focus and alignment. I have a Zeiss Conquest 3x9x40 and I just love it!!!!! Another option would be a Zeiss Conquest 3.5x10x44. Leupold VariX III 3x9x40 would be another good option. I compared the two when I bought mine and for me, the Zeiss was better. In my honest opinion, your gun is only as good as the optics on it and if you have the available funds....you WANT a good scope with good glass. Good luck.
