The Neostead shotgun, also known as the NS2000, had been designed by two South African engineers, Tony Neophytou and Wilmore Stead, in the early 1990s. They originally patented the pump-action shotgun with forward-sliding barrel in 1991 and then modified the design for dual feed tube magazine by the 1993 (according to their second patent application). The working pre-production prototypes appeared in the late 1990s, and production began in 2001. At the present time Neostead is in production and is marketed worldwide by the South African company Truvelo Armory. It represents a very interesting and promising design of a combat shotgun, but it's still to be seen if the Neostead will be adopted and used by any major police or military force.
