If it is a cantilever barrel,you don't need a mount, just the rings. I have almost the same set up you do. I used Burris Signature rings and mounted a Nikon Slughunter 3-9X40 scope. I have has 0 problems with it. Good luck.
That's right! I didn't even think about that. Thanks for knocking the stupid out of me.
