I'm considering putting a receiver sight on a flat sided receiver (like a Wichester 9422 or a Marlin 39, drilled and tapped for side-mounting) and I wondered why those of you who use them chose one over the other. Just to jog your memories, this could be functional or not - better looking, appears stronger, history of the other one breaking, good/bad customer service, arm returns to zero, didn't need to use a higher front sight, or anything else. Also, would your reasons/choices be different if you were putting it on an accurate bolt action, i.e., not a flat-sided receiver?
