I've never seen one. I'd have to be a forward mounted "scout" type scope, LER, though. As with the original 94 Winchester, cartridge ejection won't allow anything over the top and side mounted scopes kinda suck. Or, maybe I don't like side scopes because i shoot lefty, but it's just not the natural place for a scope.
Have you tried B Square? If they don't have it, it probably isn't made. The 92 is a common action and B Square might have something.
Ah, went to b square and yes, they have a side mount. Me, I think it's an abomination, but some can't see irons I guess. I have a ghost ring aperture on mine, just FITS the motife.
