In conclusion we have those who say if you buy the top tier most expensive rings you don't need to use anything between your rings and your scope tube. And we have others who say they do use rubber cement, electrical tape, latex cut from a latex glove, spray adhesive, liquid rubber, cash register receipts, mailing labels, rosin, cornstarch, and various other things to increase the grip. One guy on another thread even mentioned using lapping compound between the rings and the scope. Oh and let's not forget super glue and I would like to add Flex Seal liquid rubber. So that about clears it up, thank you everyone.
