rem700man, have you inquired about the Leupold QRW's? I found the same thing here with the QR's but all stocked the QRW's. They work on weaver bases and therefore are a cheaper solution. This and the fact weaver have themarket share when it comes to mounts I believe is the reason shops say HUH or don't have the QR's. You could also try to locateWarne Quick Detatch rings, they also work on weaver style bases. Both are available in high ringsfor the 50mm objective.
The other option of course is mail order, cabelas stocks the WarnesQD's & Leuy QR's.
I feel your pain [

]and ended up putting on a set of DD's that I had on hand.
Best of luck.
