So the idea is what is important, not the firearm itself. The idea is that no matter how many regulations are in place by the government, people will always find a way. This idea puts the power back into the hands of the people. That was the creators intent. It wasnt to supply criminals with guns, its to protect the little guy. The name is also unique, the liberator, which it shares with the liberator that was dropped over france during WWII. Its a fire once and discard weapon meant to scare those in power.
It does have a metal firing pin, metal springs, and a metal piece in the plastic so it conforms to some law about not being "invisible". Everything else is built via a 3D printer. Dont understand what all the BS is about anyone with hand tools, drill press, lathe, cnc can product their own weapons and to a much higher quality.
You should see the AK47s Afghans are producing in Kabul....now thats scary.
