Scope mount for Benelli M1 Vent rib/Tru Glo Vent Rib sights

Hey all, planning to try a red dot on my Benelli M1. It has a vent rib barrel. I’ve seen references to vent rib barrel scope mounts on-line but have not been able to track it down. Antone here have any experience with them?

On a related note, I’ve seen snap-on-the-vent-rib sight sets from Tru Glo. Are these GTG? (My Benelli currently has a bead only).
