With that kind of budget, I'd buy the 2 1/2X Leupold and Leupold mounts - offset rears- and go. I presently use the no-longer-manufactured Weaver 2 1/2X. It seems like a good scope and has help up so far. It is easier on the budget, but is, unfortunately, no longer made. I would prefer the even better Leupold if I had the money.
