I apologize for being an asshole...
after reading my post i realized it was pretty immature...
2 dots and 3?
er...that definitely looks like burst fire and maybe full auto.
If thats what it really is, he should get rid of the firearm.
Sorry to say but that is definitely in the illegal zone and what he has is an unregistered machine gun.
Big no no by the ATF, and if caught will demand jailtime.
I'm not sure exactly on how to proceed with this, since i have honest no experience with an illegal firearm.
Im assuming best course of action is to contact local police department or ATF branch and ask directions on how to dispose of properly.
The least he can do?
Salvage some of the parts, like the pistol grip, buttstock, upper receiver, etc.
And dispose of the lower as deemed.
If hes real lucky, maybe its just an RDIAS, or some other full auto part that was put in. In that case, im guessing you can dispose of that illegal part, and dont forget the full auto bolt carrier. Once again though, do not quote me on this... only speculation.
Either way, 2 dot and 3 dot is a bad sign. =o(
Sorry to hear that
