Via The Firearm Blog I learned of some great news, Defense Distributed has successfully printed an AK magazine:
Since all but the most expensive 3D printers lack the ability to work with metal (that will change) you still have to supply a spring but the rest of the magazine can be printed. You can count this as yet another nail in the coffin of gun control. Advancements like this effectively render New York and Colorado’s recent magazine bans meaningless.
Head over to Defense Distributed’s website and download the plans.
