ATF redefining what is a "receiver" is just another example of Federal administrative "over-reach".

AND, they want to define any part that is visible to the exterior of the weapon, and encloses any one part of the firing mechanism, as a 'receiver'.

That would make a trigger lock into a 'receiver'. It is exterior-visible, and encloses the trigger. Example:

NUCKING FUTS.
