Making/assembling? Almost all NFA guns when modified to be shoulder fired consists of a.) removing several inches from the barrel and or, b.) simply applying a butt stock as is done in any transformation from pistol to rifle. MG's are exempt
The base platform has already been made or assembled realistically. Does the addition of a stock no different than adding any other external feature or taking a hacksaw to a barrel constitute "making/assembling" and furthermore, if someone else other than the stamp recipient applied the stock and you are only "in possession" what then?
I think this is where the 922r doesn't apply argument originates from. I trust ATF as much as the liar in chief which translates to zero so I have subbed US parts on all applicable NFA weps. Idiotic law.
