Vent rib scope mount

[Octopus17]

I am trying to find a way to mount a reflex or red dot to my Browning Cynergy.
I am going to be using it for coyote, i have extended pattern master chokes, but can seem to
figure out the mounting process.
I have seen a lot of b-square? mounts. just looking for some advice.

I woild not mount anything like that on a rib the possibility of damaging the rib is very good .
