Jammed adjustment rings on my scope = HALP!

[Crimper-D]

Through an incredible run of serindipity, I managed to find a 99%
UNERTL 2" 24X Target Scope Complete with lens caps and Posa Mounts. That 26" long sucker bolted right on my Winchester 52B - thereby increasing the weight of the whole package to about 12.5lbs!Finally got my benchrest rimfire gun !
Only one lil problem The threads on the parralax adjustment rings are frozen SOLID! = The scope is permenently set at 50 yds and shoots astonishingly small groups at that distance, but 25yds...50ft. = FORGET IT! :banghead:

Any suggestions on how to bust this set of rings loos without marring that beautiful instrument would be greatly appreciated, especially what tools to use

Get one of the new Sears Craftsman rubber strap wrenches. But, I allus thot 50 feet and fifty yards were identical settings; they were on my 513 with iron sights.

Put a bit of penetrant on the threads and wait 24 hours before you use that strap wrench.

Hey THANKS for the tip Pistolsmith...

Went out to Sears and bought one of the rubber strap wrenches ($9) and it WORKED! Everything's in working order and properly lubed up now. Old/new scope it had been stored for about 40yrs - a wonder the blueing finish was intact, but those fine, fine threads It wasn't rust that was jamming the threads - it was dust
Thanks again......................
