[tombogan03884]

What is the "state of the art" nowadays ?
Especially metal printing , what can they do ?

2nd, What are these "ghost guns" I've seen  advertised ?
 What does the little milling machine require ?
Electricity only ?
Or do you need a compressor as well ?

  anything you can cast you can 3d print, but with eternal  details you could never cast. In almost any metal.


There are lots of jigs where you use a low powered router to  finish  80% ars.    Basicly you hog out for the mag and trigger group.  Drill a few holes.   Ak its a drill press and some rivits.

I expect that in the next round of gun control Bills will be something that lowers the bar for unfinished receivers.  Currently an 80% is legal.  I expect to see 50% as the new threshold.  Anything that resembles a finished receiver.  Next will be that if you purchase one of these you will be required to serialize it, with a serial number already assigned, within a certain amount of time, and at that point you will go through the NICS.
