Yeah, that's a good way to go. I've found cheap Leupold Rifleman aluminum 1" rings work well for mounting G2's:
That'll work on any chunk of rail mounted to the rifle or on the scope using those C.O.R.A. rings posted above.
BTW, you can get high powered LED's for G2's which are a couple times brighter than what they come with. It makes for a pretty good combo.
