This isn’t your everyday crypto scheme.

This is foreign bribes being laundered.

The part you can easily print, however, is the receiver.

The receiver is the part that’s legally a firearm. While I think it’s neat I can customize my firearms, I do acknowledge that someone who is prohibited from owning a gun can very easily print a receiver and order the rest of the parts from Palmetto State Armory to get a perfectly-functional firearm without any background check being performed.

I also don’t know the solution to the problem though. As 3D printing, desktop CNC, and other forms of DIY manufacturing improve in quality and decrease in price, it will be very hard to regulate home-brew weapons.
