Because then it would have the shoulder thing that goes up.
Seriously though, anything with a barrel shorter than 16" must be registered (and taxed) as an SBR or put on a pistol lower. There are other aspects to this but I won't put up the wall of words here. Check out any number of gun forums (take anything on AR15.com w/a grain of salt though) and look for the NFA threads.
