I just picked up a Benelli M2 slug gun with a rifled barrel and iron sights. It came drilled and tapped. I went to Bass Pro yesterday looking for guidance on what kind of mount and rings to use, but unfortunately no one at the gun counter had a clue. I'm pretty much set on a Leupold VX-1 for a scope. Does anyone else have a M2 scoped? What setup do you suggest? Appreciate the help.
