Always just used Ruger rings (yes, lapped...) on any application that I considered "permanent" and never experienced an issue. If you take them off and then re-attach, they are usually only about a single MOA off.
I do have a #1 that is one of my main and favourite hunting rifles, and I keep two scopes sighted-in and ready for it at all times in Alaska Arms QD rings. The QD levers are a bit obtrusive (as most QD levers are) but they come off and then go back on with virtually undetectable shift in POA. Good quality stuff.
