I don't know much about printed guns. The barrel, striker and extractor have to be metal, right?
Yeah. In this case, it's the same thing as milling out an 80% frame. You're making a hunk of plastic (that the government considers "a gun" and tracks/requires serialization) and inserting a bunch of easily purchased and not-tracked metal parts to make a functional firearm.
Yep. Purchased or made. Barrel blanks are unregulated lumps of metal. Drills are just tools. Traditional button rifling requires (I think) a slightly specialized lathe, but huge advances have been made fairly recently (past decade): one can etch rifling into a barrel blank with a 3d printed plug, flowing saltwater, and an electric current. Chamber cutters/reamers are also just tools.
Oh, no, it totally is.
$40 for the cheapest brand, $100-$150 for Glock OEM barrels, $300 for very very fancy ones. No regulations, background checks, or shipping restrictions.
