Twenty dollars or for set of leupold bases, 20 dollars or so for a set leupold rings and you be set for as long you want to be. If you want to spend a little more, I'd lap the rings to smooth them out; i've been told it helps accuracy, but i'm not sure if it really helps out or not. I've also heard good things about warne. I just can't justify spending more money on something that isn't going to hold any more secure than leupold.
