I have a used set of bases, claw mounts and 26mm rings for a Sauer 202 with screw fitting receiver. They are EAW so the quality is good. I can change the rings for 34 mm if required. 75 posted
I also have again by EAW a spare set of the claw mounts and depending on the ring requirement a couple of spare sets of rings. Sorry no 30mm. These will be 30 for the rings and 30 for the claw mounts.
If you are interested or need some further info please PM me
