This is just a bunch of stuff from the FTC about his.
When you read this get out of your head
that the parts kit you have in front of you was or ever had been a firearm. What you have in front of you really is a pile of scrap steel that just HAPPENS to have origins from another country.
If a parts kit were anything other than scrap metal, i.e. a firearm, then be sure there would be more controls on them and ATF would not allow unrestricted transfer through the mail with them.
ATF's jurisdiction on your parts kit leave when you turn in your F-6A at the customs office (except if you do something stupid and have a kit and the parts to finish it like a blank original dimension receiver with it, or if it was demilled improperly and not removed from federal control).
From then onward you are a proud owner of expensive JUNK! FTC controls junk like this. You remanufacture and do your bit to where you put in X hours of labor and have ultimately remanufactured it to where it has been removed from the purpose of what it used to be and is now operable only in the semiautomatic system that you are running in your clone.
I have my own AKM FCG's that I submitted to ATF for classification and permission to use. Guess what they're made from????? Imported AKM FCG's and all I do is remachine them a bit and give them a whole new contour. I call them my EZ match triggers.
I don't buy US made FCG's.
