I have a Ruger M 77 Mark 1 and I would like to put my Leupold VX-R 3-9x40 on it.I have to get 30mm rings but everywhere I look, they are only sold as singles, not in sets. A sign of the times we live in, perhaps, but none of the people at Cabelas or a couple other onl8ne stores seem to know which is the front ring and which is the back ring ie the number stamped into the ring to differentiate betwen the front ring and the back ring. Can someone please enlighten me ?? I have also tried the Ruger website to no avail.
