Not sure what relevance that has, other than to muddy the waters further, but to me a gun with significantly shorter effective range than an M16 (or an AK74 for that matter) doesn't qualify regardless of what words happen to be in the name. In most instances it also doesn't have a folding stock, but that's besides the point.
Questions like this will always come up, and take the admin's time, whenever there's a rule based on examples and "etc" -- a hard and fast rule such as "must have a barrel 20 inches or longer" would solve it. It wouldn't keep people from asking, but it would stop them from arguing.
