Rails are easy to work with, cut them off fore and aft of the action ports, mount rings in last slots, use thinner rings than Talley or Nightforce etc, if steel rail, cold blue the saw/file marks, if aluminum paint em or get em cerakoted.
That works for me. I’ll even put a bit of bedding under them before I cut it. It’s nice to have the extra slots and the extra MOA doesn’t hurt in some cases.
