Right now I have Burris Signature Zee 30mm rings with the plastic inserts. I love that they leave no marks on the scope, but I hate that when I need to detach the scope from the base, I have to take everything apart. I've had to do this twice thanks to a scope base that keeps coming loose. Anyways, I am looking to upgrade to better rings but I really don't want any marks on my SIII. What are my options?
