If you want to be close to previous zero, cheap QD's aren't going to be great. 
I don't know of ANY rings that are custom fitted that can return to exact previous zero.

For one thing, there's a big difference between Weaver & True Mil Spec Grade Picatinny rings.

As far as 30mm high Dovetail QD, I suggest that you have a 20-40-60moa Picatinny Mil-Spec rail professionally installed. Then you can use Mil-Spec Picatinny 30mm QD High profile rings that will actually come very close to previous zero. 
This would also allow you to keep your scope centered & zeroed where you want it. Directly over center of bore & optically centered in a mirror, with a near/far zero you want. 
This of course also allows you to make the best use of your mil-dots. 



I don't think QD 30mm Dovetail rings are made. I don't want anyone wasting money on rings they hope to do something they don't/can't. If being within a few inches of last perfect zero is okay, fully understandable. 
I just had to point out that what's sometimes labeled as LE Grade, wouldn't be found on any Expert Marksman's dedicated rig. 
Hope the links help someone because there's a lack of agreed upon specs in the airgun industry and builds. 
 
James is right. I’ve used the UTG QD on dovetail rails before. Repeatability of zero is “ehhh” when taking them on and off but doable. I must say I do have them in Picatinny on two of my guns but seldom do I remove the scope from the gun.

DO NOT use those cheap @$$ adapters. You never will be able to keep your bore to center of optic the same. 
been there done that....
