They didn't research very well. You can finish an 80% lower with a drill press. A router helps, but it can be done with a drill press. Milling machine is definitely not necessary. The polymer80 glock frames are even easier. There is a guy on youtube finishing one on his tailgate with hand tools.

"The Gun Control Act of 1968 and associated legislation restrict the buying and selling of weapons. This still leaves the possibility of legally making your own weapon. That doesn�t just mean crude zip-guns made from basement parts: It turns out that it�s easy to buy most of an assault-style rifle�the upper receiver, barrel, and stock�prefabricated. The tricky bit is the lower receiver, which is where the most complicated mechanisms of such a firearm reside. A cottage industry supplies blocks of metal that are 80 percent finished lower receivers. It�s up to the aspiring DIY gunmaker to machine mill the final 20 percent of the piece so that it can accommodate the functional guts of an automatic rifle, including the trigger mechanism.

This requires high-end technical equipment and specialized skills. The typical method of finishing a lower receiver involves a shop-grade computer numerical controlled (or CNC) milling machine capable of precisely cutting aluminum. "

^^^That's why I was wondering what law the judge used to block it.

I can buy a kit gun on-line. Making your own gun is a non-issue.

Good guys don't need to and bad guys can get a gun with far less effort.

I just use the copy function on my printer. Not as pristine as the original but goes bang when the trigger is pulled.

Can you imagine thousands of felons or disturbed minors (who may want to shoot up their old school) printing out their own guns?
