This probably wasn’t on lawmakers’ radars.
Even if future gun laws ban certain firearms or parts, 3-D printers could enable people to build the banned parts on their own.
“This is a symbolic challenge to a system that says we can see everything, regulate everything,” he said. “I say, ‘Oh really?’ My challenge is: Regulate this. I hope with that challenge we create such an insurmountable problem that the mere effort of trying to regulate this explodes any regulatory regime.”
Wilson’s group has posted several videos to YouTube of AR-15s firing rounds with 3-D printed high-capacity magazines and lower receivers, the part that includes the firing mechanism and is the only regulated portion of the gun if it’s bought over the counter. Wilson’s parts are made from high-grade polymer and retrofitted to the bodies of existing weapons. The receivers are made able to fire by adding over-the-counter springs, pins and a trigger.
