I don't usually endorse a product, but I am impressed. I am putting a new Conquest scope on my Tikka Tactical. Looking at rings, so many..., and went with the QRW's by Leupold. Installed the rings today on the Tikka base, whipped out the Wheeler alignment tools and wow, perfect touch at the point. I put on my magnifiers to be sure, and they are so centered on each other that I could not find a bit of off alignment. I know the combination of great rail, and great rings is not that difficult to make but it is sometimes hard to simply buy and find when you use two different suppliers and in this case two different countries. The attention to details is what counts I guess, and I got very lucky this time. No lapping is always a good thing.
