I think the Ruger rings are excellent as they are - as always, lapping is a good thing. Signature rings are also excellent. I checked the Burris web site and as I interpret it, you cannot get Ruger style Signature rings. But they make a Ruger to Weaver adaptor, which allows you to clamp the adaptor onto the Ruger receiver, and then use Weaver style rings (Burris Zee style Signatures). So - using that adaptor, you could use Signatures with the inserts. I really do like the Signatures, but I have several Ruger rifles that I have had such good results with Ruger rings with, that I have used the Ruger factory rings and am pleased with my choice to do so. The Ruger setup is an excellent one as it comes from the factory. On my Ruger #1s, I use offset Ruger rings for eye relief issues. There are some good choices available, no matter which you prefer. Good shootin'!
