3D Printed Rifle Receiver Fires Hundreds of Rounds

That's gonna be a tad hard to regulate

On Monday, with little fanfare and less comment — primarily because none was needed — Defense Distributed unveiled a 3D-printed lower receiver for an AR-15 that stood up to hundreds of rounds of fire. Succinctly, the video on Youtube was accompanied by the statement, "Does not fail from firing stresses. 600+ rounds." Just as important, and the purpose of all this effort, the group made plans for the receiver available for download by all and sundry at DefCad. Defense Distributed's video and 3D printer plans are a clever and powerful blow to politicians' efforts to restrict Americans' abilities to own the means of self-defense. They may also be a glimpse of a future in which human liberty is largely dependent on an ability to limit the reach of the state through technological innovation and grassroots defiance.
