I have a tall Weaver for a Savage 30/06, haven't used it yet though. Waiting for a front sight ramp to come in the mail.
I have the mauser sight on a small ring Swede in 9.3x62 with the XS striped front post. It's a great combo on this gun.
They offer an aperature with a taller shank that is also threaded for Williams type screw in aperatures. I'm going to get one through Brownells, sometimes the ghost ring is too ghosty.
