Can you make an assault rifle with a 3D printer? Apparently, it’s possible … and this Texas Law student figured out how to print a semi-automatic rifle from the comfort of his own home.

Now, he’s putting all the information online so that others will join him.

Posted up by VICE, the clip is “a story about the rapid evolution of a technology that has forced the American legal system to play catch up. Cody Wilson, a 25-year-old University of Texas Law student, is an advocate for the open source production of firearms using 3D printing technology. This makes him a highly controversial figure on both sides of the gun control issue. MOTHERBOARD sat down with Cody in Austin, Texas to talk about the constitution, the legal system, and to watch him make and test-fire a 3D-printed gun.”
