Further review of the ruling...

Te following seems to be the main point that is in favor of the MechTEch...
Held, a firearm, as defined by the National Firearms Act (NFA), 26 U.S.C. 5845(a)(3), is made when unassembled parts are placed in close proximity in such a way that they:
(a) Serve no useful purpose other than
to make a rifle having a barrel or barrels of less than 16 inches in length (e.g., a receiver, an attachable shoulder stock, and barrel of less than 16 inches in length); or
(b) Convert a complete weapon into such an NFA firearm, including –
(1) A pistol and attachable shoulder stock; and
(2) A rifle with a barrel of 16 inches or more in length, and an attachable barrel of less than 16 inches in length.
Such weapons must be registered and are subject to all requirements of the NFA.
The words 'other than' imply that having a pistol, a separate 16" barrel and a stock could serve a purpose 'other than' to create an NFA weapon. It can be argued that while you are capable of making an NFA weapon, you are also able to and intent on building a legal 16" carbine/rifle with these parts. Only the court will tell you if I've interpreted the law correctly. The argument certainly holds water but I won't be testing it like this
I am not an attorney but from every interpretation I can come up with, the CCU is
in full compliance with this ruling. Installing it does not constitute creation of a new weapon and it cannot be used to make an NFA regulated weapon without modification.
I am currently on the waiting/callback list for MechTech to take my order. I think I'm gonna go for it if my finances cooperate...
