Sparrowvsrevolution (1926150) writes "Slashdot has closely followed the developing controversy around Defense Distributed, the group that hopes to create 3D printable guns to defeat gun control legislation. The group has yet to create an entirely 3D printable gun. But it's already testing the limits of gun control with a simpler invention: the 3D printable ammunition clip.
Over the past weekend, Defense Distributed successfully 3D-printed and tested an ammunition magazine for an AR semi-automatic rifle, loading and firing 86 rounds from the 30-round clip. That homemade chunk of curved plastic holds special significance: Between 1994 and 2004, so-called “high capacity magazines” capable of holding more than 10 bullets were banned from sale. And a new gun control bill proposed by California Senator Diane Feinstein in the wake of recent shootings would ban those larger ammo clips again. President Obama has also voiced support for the magazine restrictions.
Defense Distributed says it hopes to preempt any high capacity magazine ban by showing how impossible it has become to prevent the creation of a simple spring-loaded box in the age of cheap 3D printing. It's posted the 3D-printable magazine blueprints on its website, Defcad.org, and gun enthusiasts have already downloaded files related to the ammo holders more than 2,200 times."
