You know the intention of gun control when the laws made have no rational basis.

I should add—because my own class III FFL didn’t know this—you cannot make a pistol into an NFA rifle and then reconfigure as a pistol again. Once it becomes an NFA rifle, it cannot he made into a pistol by changing the stock. You can remove it from the purview of the NFA, however, by attaching a non-NFA barrel to it.
