I am with FEENIX on this. I tried a set of the Burris Signature Zee rings a few years back I and use them as my standard. They eliminate the lapping and bedding. As well I can correct for receiver screw hole location being out of true alignment with the barrel. And....I can add or remove up to 40 MOA of elevation as desired by choosing different inserts that come in the ring kit. They are not heavy or bulky as compared to some of the more popular choices out now. In fact....they are much lower weight and profile than some. Worth a try.....
