A phone case built from a M-16
Or the clip of one. As the "de facto standard for magazine reliability and durability" for military and law enforcement, Magpul has been supplying different walks of armed forces for awhile. Now they're bringing that reliability and durability to your iPhone or Galaxy with their Field Case. And made from the same synthetic rubber as their tactical accessories, it features a PMAG-style rib and snap-on design, making it as useful as it is downright cool.
