New Mini CNC Mill from Defense Distributed

Cody Wilson, the guy who made the antigunners piss their pants with a 3D printed guns, is at it again. This time, it is a mini CNC mill that will retail for under $1500 and come ready to go out of the box. It's big enough to do 80% AR15 lowers and 1911 frames. Of course, it's not limited to making guns.

The hardware and software are open source. The website says that it'll be shipping for "Holiday 2014," and it's available now for pre-order.


This has the potential to be more significant for the right to bear arms than 3D printed guns. This will allow you to make the receiver (i.e., the part registered and controlled in the US) out of metal, from which the majority of guns are made. With many traditional designs you cannot simply substitute synthetics, due to engineering constraints.

Making gun control moot via technology will be one of the greatest advances for personal liberty that we see in the 21st Century.
