This. It is pretty commonly known in the NFA world that the host takes on the attributes of an NFA firearm while the part is installed. The reason is that though the fun parts are "firearms" as defined by the NFA they are not firearms under GCA. Under GCA a gun that goes multi-bang is a machine-gun, no matter how it got that way. So while the fun parts are in a Title 1 firearm, it's not a Title 1 firearm anymore because it can't be since it goes multi-bang which isn't allowed in a Title 1 firearm
Unfortunately, ATF says that it returns to Title 1 states immediately upon removal of the registered part. Now, none of this is law really, just ATF's interpretation. My gut says you would be fine for the short period performing a repair but I would want it in a written opinion.
I run into this with a RLL now and then. When the RLL is in my AR, the AR itself is a machine gun and I can put short barrels etc on it without an additional tax stamp.
The moment the RLL comes out, the short barrel has to come off too. If I put the RLL in my AR receiver that has an actual SBR tax stamp of it's own then the RLL can come and go without changing anything.
Now, in this case you are talking about a repair to the host gun. For this I think you really will need to send a letter to NFA Branch and ask them your very specific question, and keep a copy of their response.
Some folks will put the serial number of the host on the Form 4, what some call "marrying". This ties the pieces together and might make all this easier, but I don't know if that's something the OP wants to do.
From the Bardwell archives:
A 14" M1 Carbine + MG requires the registered MG and the registration of an SBR.
they don't always "stack" sometimes they over-ride eachother. i just bought a machine gun that has a shoulder stock and a 6" barrel. this would definitely qualify it as a SBR, but i am only required to get one stamp. MG trumps SBR. think about it - that would mean EVERY M11 is a two stamper, which simply is not the case.
edit to add - there are situations where you need two stamps, like a sbr with a suppressor. in that case, they would "stack". however, a mg with a short barrel is a one stamp gun.
Hmmm .... that's not my understanding, obviously, while the parts are all together anyway. I thought TexasRifleman's post explained it pretty clearly, but I'm open minded, do you have a reference? The more info I have, the more clearly I can pose my issue to the BATF.
What are you basing this claim on? It goes against what pretty much every NFA firearm owner believes to be the case.
He made it up.
As I understand it...
Machine gun with silencer: transfer of registration of the machinegun requires a Form 4 with the serial number of the machinegun; transfer of registration of the silencer requires a Form 4 with the serial number of the silencer.
Machinegun kit (T17 or T18 conversion kit for carbine; drop-in-auto-sear conversion for M16) in a shortbarrel rifle: transfer of registration of the machinegun conversion parts requires a Form 4 with the serial number of the DIAS or conversion kit; transfer of registration of the SBR requires a Form 4 with the serial number of the SBR.
A short barrel machinegun (eg MP5) will have only one serial number and one Form 4.
