Dicks had a meltdown, for good reason.

You sorta got it right - the wrong way.

The trigger group is  the lower reciever. The barrel mount and bolt carrier are parts of the upper and not serialized. If I am not mistaken ATF does not want them torch cut - but bandsaw cut. Reason - they want to be able to identify the unusable parts. If you used a torch - it would make a puddle. Hard to identify a puddle.

But - all the internal parts, buffer tube, stock - and the entire upper can be salvaged and sold as parts.

Upper recievers can be bought and sold with no FFL paperwork. Only the lower requires a 4473.

The ATF actually specifies a torch for this sort of work.  From the relevant page:

Each cut must completely sever the receiver in the area indicated by the diagonal lines.
 

[*]The receiver must be completely severed in each area indicated with a diagonal torch cut.
 
[*]Cutting by means of a band saw or cut-off wheel does not ensure destruction.

Pretty dumb.

As a machinist who also welds - I can absolutely guarantee that if you were to cut aluminum reciever apart with a bandsaw - it would never function again as anything other than a paperweight.
