That is not true. It is how the weapon is first configured. If you by a lower, assembled or not, and it is first configured as a pistol, it is legally a pistol and can be changed to a rifle and back without issues regardless of what was put on the form.

The lower can be registered as a rifle, pistol, other. Doesn’t matter.
