You can modify either to be shorter but you have to first register it as an Any Other Weapon and pay the $200 tax stamp. There is no way, to my knowledge to legally convert a weapon to fully automatic though. There are also other laws like not being able to put forward/vertical grips and stocks on pistols. That's why carbon 15 pistols, etc. always come with exposed buffer tubes and no stock.
