If you manufacture an 80% lower and assemble it as a weapon you cannot transfer it to anyone. Period. Thats Federal law.
See my link above. Yes, you can, but it may not be a good idea and you certainly can’t hand it over to someone else immediately upon assembly.
Understood, but the article implies the firearm was made illegally so.................
Yes, you can .You cannot, however, make it with the intent to sell it.
As I recall there was some question about Interstate Commerce. The way the laws were introduced, through regulation of Interstate Commerce were being tested. There was some thought you COULD manufacture to sell just about anything as long it was only for use inside the state of manufacture. IIRC they seriously screwed with someone who was doing this and IIRC he won.
I believe you are mistaken.
You cannot make the firearm for sale without a federal license. You must make it for personal use.
After some period of time it simply becomes another firearm you own.
You may then sell it without hindrance.
The traditional time period for removal from a commercial category to a private one is one year.
The BATFE suggests that you put a serial number on it.
It is not required by law, because you are not federally licensed manufacturer.
California requires you apply for a serial number before you make a personal firearm, but in most states it is not required.
