I want to mount a Trijicon RMR dual illumination on an M2 20 ga. Has anyone done this. I am looking for a low profile solution similar to FF III on a 336 base. I thought about trying to drill and tap the 336 base to match the Trijicon mounting pattern. I have no idea if this will work. I do not want a picatinny or Weaver style mount. The extra weight will be tough on the receiver and I want it as low as possible. Thanks for any help.
