Benelli SuperNova weaver mount options

[renegadeg2]

Hi,

I have a 12 gauge, Benelli SuperNova, smooth bore.

Looking to install a mount for a red-dot sight, without tapping and drilling - as that will get in the way of the built-in bead sights.

I was looking for a saddle-style mount, but haven't found anything for the SuperNova.

I've seen the AimTech and B-Square stuff online in the US, but not sure what is available here in Edmonton?

Has anyone tried what I'm doing? Any suggestions?
