Not new. They showed it at the 2017 SHOT show. It looks like you can get one for around a grand. A regular KSG is $650-700.
Fully loaded with 00 buck, it weighs 11 pounds. Meh. With mini shells, that's $41 worth of ammo. It's the same overall length as a typical 18" barreled shotgun.
It's just too heavy, expensive, and impractical for me.
