Sorry to revive an old thread, but - I picked up a good condition Rossi Cyclops that included a B-Square mount and a Leupold M8 2X extended eye relief scope. The B-Square mount is screwed into the top strap of the gun. This is a non-ribbed barrel and there is a notch along the length of the barrel that looks like its designed to accept a scope mount. I've been doing a little research and I can't find any evidence or pictures of anybody mounting anything other than a screw in type B-Square or similar rail. I'm curious if these guns were factory drilled & tapped for this mount or if this was commonly done by a 3rd party.
Anybody who might be the original owner of a cyclops who could chime in on this?
