3) Cody Wilson
The former head of Defense Distributed took a major step towards gun rights over the past several years. A self-proclaimed crypto-anarchist, Wilson is the creator of the first 3D-printed gun. With Defense Distributed, he has worked for years to produce files capable of printing various weapons. In 2013, Wilson had his first major breakthrough, successfully test-firing a small 3D-printed gun called the Liberator.
