RE: Rinigs and bases for new scope.
Generally shotgun scopes have longer eye relief than rifle scopes.
I used T/C Gorilla Grip mounts on my Genesis with a Leupold Rifleman 2-7x33, and I was just able to mount the scope forward enough to fit me. Don't know if those mounts would work with that scope.
Others have used different bases and mounts, and I'm sure someone can point you right.
