Thanks in advance for any help/info. I have a remmy 5r in 308. Currently it has a mark 4 4.5-14 ffp mildot. My gun smith mounted it with talley rings. I seem to see more rifle optics mounted with a steel rail and picatinny style rings. What would be your choice to mount my new vortex razor 5-20? and if its the rail with picatinny rings, should I get a rail with 20 moa angle? I'm kinda new to the bolt gun arena. Thanks
