There was a time when this would have been considered a dumb thing to do. So do you know of anybody who has placed a scope on a lyman or maybe even a zuave? My uncle once told me the gunsmith up the street from him told him not to waste money on an inline because he could attach scope mount to his zuave in 58 cal. Now I have a book with pictures of different Confederate sniper rifles with scopes mounted on top of them. Sure they were the old brass style scopes, but I don't see why someone couldn't have a modern style mount and scope attached to a side lock muzzleloader. Couldn't you drill and tap the barrel or even weld a steel mount to the barrel? I sold my traditions percussion gun because I couldn't see the sights all that well. Maybe I should have hung on to it and put a fixed low power weaver on it. It's not like it was worth a whole lot anyways.
