Yup. It probably stabilizes the camera quite well, but only an idiot would wander around with it on the street or in a war zone. It probably would be OK for motor racing and other organized sports where organizers control access, but I think I'd be sure to show it to whoever's in charge of site security.

The Soviet Union deliberately exported the manufacture of Kalashnikov rifles and ammo as an inducement for allies and client states. It was a powerful inducement, too, because local manufacture of weapons came with jobs for the boss to hand out and lots of other perks for the folks in power. The late conversion to IP and patent rights is pretty amusing. I'm also pretty certain the the AK design as a whole is not patentable. As others have pointed out, much prior art is involved.
