I should have mentioned that my double rifle is a sxs.

I currently have a Leupold M8 2x scope and when I put it on the rib with rubber bands, the rear scope bell is alligned with the breach face of the gun. I can still mount it further forward but it looks really good being flush with thebreach face; and the plus is no scope to interfere with loading.

Kindest regards,
