Is it possible for "Assault rifles" as we know then to have been invented in the 19th century? After all, they had rifles, they had gatling guns, is really to much a stretch for someone to say "what if we put the fire-power of a gatling gun in the hands of a single rifleman?" In OTL the AK-47 is said to be so simple that it can be copied with 16th century gun-smithing technology, So is it possible to invent something like an AK-47 in the 19th century? If so, who would be the country first to make them? How would the presence of assault rifles in the 19th century change the history of warfare?
