Illegal-To-Own Thompson Parts

[345 DeSoto]

What SPECIFICALLY is the illegal part on a Thompson Sub Machine gun to own? I've heard that it's the receiver (the part that the bolt is installed in), and I've also heard that is the trigger group housing that holds all the selector parts...

Just the receiver. There are lots of parts sets around of some returns from the Soviet Union. All just missing the receiver.

Specifically, the receiver, which is the serial numbered part.

Everything else, including the trigger group are just parts.

legal parts

same with the 1919A1 parts you get all parts except the right side plate.$ 70 buys you a dummy side plate.

The only time a part, in and by itself, or in combination with other parts, is a machinegun is when it can be used to convert a gun that is not a firearm under the NFA definition into one that is. There are not many. The six part "kit" that can be used to convert an M1 carbine to a selective fire weapon like the M2 carbine is one (the whole kit is a machinegun; the individual parts are not unless all six are present). The AK-47 full auto bolt carrier is another, as is the drop-in auto sear (DIAS) used to convert a semi-auto AR-15 into a full auto weapon. Most other machinegun parts are just parts.

The AK-47 full auto bolt carrier is another,

Come again?
There's a whole lotta legal semi-auto Kalashnikovs out there that were built from parts kits that included a full-auto bolt carrier (including one I built).

AFAIK, converting a semi-auto AK to full-auto involves notching one of the rails and drilling a pivot hole for the auto-sear along with a full-auto trigger group, hammer, and bolt carrier.

 

[M2 Carbine]

A UZI machine gun bolt that's been "slotted" like a semi auto bolt is also a (illegal) machine gun.

The six part "kit" that can be used to convert an M1 carbine to a selective fire weapon like the M2 carbine is one (the whole kit is a machine gun; the individual parts are not unless all six are present).

Which is why anyone that has a M1 Carbine would be wise to not have the Selector, Spring and Disconnecter in their possession. These three parts are strictly for the M2 and have no function in a M1 carbine. Since many M1 Carbines have M2 replacement parts it could be possible to have a illegal machine gun if you happen to have the Selector and Disconnecter thrown in the spare parts box.

The legal M2 "Conversion Kit" does not have to include all the M2 parts but of course it won't work unless the rest of the M2 parts are installed on the rifle.

On my wall in the middle bedroom of my home I have a dummy 1928 Thompson SMG. The shoulder stock is real, the trigger group is real, the rear sight is real, the barrel and forearm and Cutts comp is real. The receiver is an aluminum dummy receiver. I also have the bolt, Blish device, actuator, the recoild spring, guide rod and oiler for it.
But, as I said, I do not own the receiver.

 

[Funderb]

The receiver is still a firearm, even without the parts all around it.
accodring to the feds.
It is usually the only part you can't get.

Just the upper, which is the serial numbered part.

I've thought about getting a parts kit just so I could have a removable buttstock, but thats a lot of money and I dont want to take any chances with a FA lower on either one of mine, even with my SA trigger group installed. I think I'll just try to find a 1928 stock and have a buddy (with a machine shop in his basement) make the dovetail to install on my lower.

Yeah, that got my attention too. A FA AK bolt carrier just has that nub on it, right? I also thought the no-no with an AK was the cut rails/third hole.
