3D printed Mag good for 342 rounds, Defense Distributed calls it the "Cuomo"

The Cuomo (30 round AR-15 magazine) is said to have operated for 342 rounds, two thirds of them full auto. This is a complete redesign over the last prototype.

The video of the test and even the article by wired.com have been reported blocked by various sites.

The design is not available at the site that Defense Distributed has set up for "The Island of Misfit Objects" or DEFCAD .

The design is expected to be made available to the public in a few days.

As reported earlier, the group is also working on a 40 round magazine for firearms that use AK type magazines.
