The point of the article is that if you can’t legally own a firearm you can still legally buy the bits to make a firearm. If you then assemble them into a firearm you have committed a crime, but it seem it took the cops a few years to figure out he was doing this. The guns also had no serial numbers so crimes committed with them would be hard to trace.
