Okay, using their logic - if I buy one of these upper assemblies (since they say it's a "firearm"), how do I fire it?...
If it's a "firearm" then I should be able to fire it (send a round) as soon as I pick it up (literally, in my hands), right?
Nope, have to add an AR lower receiver and trigger group to the mix, in order to shoot it. Since the AR lower is serialized... what's the serial number of my rifle? Do I have to use BOTH serial numbers?
This is fucking stupid, on their part. Purely ignorant.
