“The first iteration came in 2013. It was a clunky white plastic handgun that was not very reliable and held only one bullet. The kits available today are more advanced. Plastic has been replaced with metal, and a buyer can now replicate a semi-automatic AR-15 assault weapon in just a few hours. A recent online demonstration showed a homemade AR-15 that can reliably shoot more than 660 bullets at a time. And there are no laws against making these guns.” – Diane Diamond in In Age of 3D Printers, Ghost Guns Gotta Go [via noozhawk.com]
