Leupold QRs return to zero, Warne QDs return to zero, Leupold QRWs return to zero but I don't like them much because of the ring split, and even my Burris QDs are doing a good job. Might see a half inch shift after removing/reinstalling at 100 yards. Patrick qualified his remarks with an "if not remounted correctly" which implies they need have been properly mounted initially - a source of problem for some. If you go with QR/QD rings, the choice of going with a particular type should be made with a realization that all the cross-slot Weaver types have their mechanics in the rings, the QRs from Leupold have their mechanics in the bases. Weaver style bases are comparatively cheap, Leupold QR bases are expensive. Possible trades of a rifle(or switching scopes between rifles)using the QR bases would leave you in need of more expensive bases for the rifle -lessa problem with the cross-slot types.

There are other styles of detachables out there - the B-Square Lynx peg types come to mind.I think shying away from those might be a good idea since there seems to be very little real-world feedback on how well they work and there are more readily available proven models available. There are other rings available marketed as "tactical", most of which would be quick detachable types. Most of the tactical rings are also very solidly made and fit Weaver cross-slots. They are surely a good choice but generally much more expensive. Be aware that many rings claimed to be quick detachable are not, nor are they are very repeatable. Weaver seems totally confused about this issue.

Patrick's reasons are all sound but far and away the most significant for me is his #1 - cleaning. Some rifle/scope combos benefit more from that conveniencethan others.

The most negative thing is cost compared to fixed systems. If a person shoots pellets instead of loose powder, cost must not be that much a factor. Each of us must determine our own level of economy.

So far as dumping the whole thing in hot, soapy water......is there anyone here that actually does that? Not me!

There is nothing wrong with good non-detachable ring/base combos - nothing at all. But the convenience of quick detachables is worth the price for me.
