If you want to turn your AR pistol into a rifle, all you need to do is add a 16 barreled upper and a stock. Just make sure that if you return it to pistol configuration that you detach the stock first and an forward vertical grips you may have attached to the weapon...f the firearm was already classed as a pistol with a barrel shorter than 16 inches, it cannot be converted to a short barrel rifle and legally registered. An AR15 pistol can be rebuilt as a legal length 16 barrel rifle at a later date, but not as a legal short barrel rifle of less than 16 inches.
