Defense Distributed, a designer and advocate of 3D printer-produced gun parts, recently released the newest video in their AR lower receiver tests. This particular model was able to endure over 600 rounds.

Defense Distributed also produced a printable, plastic magazine for the AR. The company seeks to keep a compendium of 3D printer knowledge online as a “wiki” platform that will be accessible to anyone.
