FWIW, check the For Sale forum (hint, hint!). In case I forgot to post there, I have a Badger Ordnance 1-piece 20 MOA base for a Rem 700SA (you didn't say what size action you are working w/, but I figured its worth a shot) and a set of 30mm GG&G xtra High 'Sniper Grade' rings. Dunno about the whole 'sniper grade' bit, but they *are* nice rings. I had a Leupold Vari-X III 8.5-25x50mm LR scope on that gun, but I'm taking it off for now, and selling it. I've been getting by pretty well w/ an SS10x42 scope in the mean time, mountied in Leupold 30mm rings on a Leupold 1-piece LR base (Redfield front-dovetail/rear windage) setup. Alternately, I have some 30mm std height Leupold QRW rings that worked pretty well w/ the same scope on the same mount; clearance wasn't a problem even w/ that big ol' scope up there.
If you are interested, drop me a line and we can maybe work something out.
