NEOSTEAD Bullpup shotgun
GunPorn wrote a post on this very interesting shotgun. It is a reverse pump action bullpup shotgun invented by a South African company.
From what appears to be the official website.

Wikipedia has this to say
The NeoStead 2000 (NS2000) is a type of shotgun developed by the South African company NeoStead. Along with the Pancor Jackhammer, it is considered one of the most technologically advanced shotguns ever created. The NS2000 has been used in trial runs for a few years by special forces like the British SAS and there are hopes at NeoStead that larger weapons manufacturers will license the production rights. Production of the shotgun began in 2001 and the first models were made available in October of that year.
The NS2000 is a 12-gauge pump action shotgun weighing in at just over 3kg, designed primarily for security and civil disturbance situations.
The firearm includes a 22.5 inch (572mm) barrel despite the overall weapon length of just 27 inches (686mm). The short length makes the weapon easier to handle in close quarter situations however, unlike most firearms of this type, it can still remain accurate at relatively long ranges. The long barrel length is achieved by using a bullpup configuration, with a rear-fed tubular magazine.
Another aspect of the NS2000 is its dual six round magazines. The selector switch can be set to left, right, or alternating. For example in riot conditions less-lethal flexible baton rounds can be used with standard rounds in reserve.
A possible production variant of the NS2000 has an 18 inch barrel in a weapon with an overall length of 22 inches. The shorter length reduced the magazine capacity to 5+5 rounds and makes the weapon easier to import or license in many countries.
Its pump mechanism operates in a forward-back motion, due to its rear-load configuration. This is different from conventional pump methods as the pump action is achieved by shifting the hand forward-back, as opposed to the standard back-forward motion of the non-trigger hand.

This photo makes it look a bit like a side by side shotgun. The two cylinders next to each other on the top are the magazines.

Steve,
Incredibly detailed post! Nice Job!
There’s almost enough information here for me to build one myself.
haha! You probably don’t need to. Some IDF commando is sure to turn up at the next wedding you go to, armed with one!
I am a big believer in the shotgun as an implement of CQB, particularly for the home defense role.
But I was under the impression that the Neostead design had been around since the 1970s, and every few years another importer tries to obtain licensing to import them into the US, but the BATmen are quite clear on their position: they consider this to be a military firearm rather than a hunting firearm, therefore they declare it to have “no sporting purpose,” therefore it is a “destructive device,” therefore its possession is verboten to us peasants, full stop.
There are a lot of things from SA I’d like to see imported into the US. Supposedly there is a polymer frame assembly for the venerable Browning Hi-Power in production there, and there are (or at least used to be) pictures of one example at Steven Camp’s excellent “High Powers and Handguns” page, but these too are forbidden to the American consumer by the BATmen.
Very nice posting. You saved me some time, as I have been searching for a nice tactical shotgun and have had some interest in the south african bullpup design since the 70’s. Apparently though, as a plain old American citizen I can’t have one. Thank you for your effort.
yeah…..seems very interesting
im still puzzled by the internal design though
