“Click, Print, Gun: The Inside Story of the 3D-Printed Gun Movement” is a short documentary by Motherboard about Cody R. Wilson, a pioneer in the 3D printed gun movement. Wilson’s company Defense Distributed is developing a 3D printed lower receiver for AR-15 assault rifles (the lower receiver houses the trigger and is regulated by Federal gun laws). They are also developing a 3D printed 30-round magazine. Wilson, who is opposed to gun control, is attempting to challenge the very idea of gun regulation with his work.
