80% FN FAL receivers

[tlbcustom]

I am interested in learning about finishing an 80% FAL receiver. How to obtain parts, completion kits and any legal issues I need to learn about. Can anyone advise?

Guessing you have one of the partially finished receivers from a decade or so ago? Those are the only incomplete fal receivers I am aware of.

I have about 12 of them.

Gotcha,

I have inspected them, and if you have what the same receivers that I have seen, then there are quite a few difficult machining operations left to do. Just cutting the slot for the charging handle will require a fair amount of setup and work. Not bad if you are doing it yourself, but if you are paying a machinist, well I would hate to see that charge. Pretty sure the barrel threads needed to be cut, and the threads aboive the barrel for the piston tube nut. I remember those receivers looking like they needed quite a bit of finish machining, almost all of the surfaces looked to be oversize to some degree.

You could buy a complete dsa receiver and start measuring, see what is in spec and what needs work. Do you have 12 fal kits to go with those paperweights?

I have barrels & the "paperweights" but nothing else. As you stated there looks to be a bunch of machine work to do. Looks to me like they have about 20% done and 80% left to go!
I would complete all machine work myself so not worried about the machining time.
I am pretty certain it is illegal to sell machining services for completing 80% receivers without an FFL manufacturing license. Even then, they would have to serialize the receiver and do a background check in order to transfer it.
I'm not sure if all the work is worth it.

It's not worth trying to complete a paper weight FAL receiver. Those are casting rejects that have flaws. Why do you think they dumped them in the marketplace ? Even if you managed to machine with all correct cuts and threads it has to be heat treated

Save yourself time , aggravation and possibly injury / death and buy new.
