Boy that's one strange looking gun.
That's kind of what KelTec is known for, that and inexpensive guns. I think the idea is that it is more stowable for backpackers that want a carbine, lots of guns can be made foldable, including anything built on the AR platform. People see a plus in these guns because the magazines it uses are Glock so very easy to get even in the 30 round size he used.
