Thats a strong looking shotgun.The NeoStead 2000 (NS2000) is a bullpup combat shotgun developed by Truvelo Armoury of South Africa.[1]

Production of the shotgun began in 2001 and the first models were made available in October of that year. It is notable due to its unusual forward pump action.
The NS2000 is a 12-gauge pump-action shotgun weighing just over 3 kg, designed primarily for security and civil disturbance situations.

The firearm includes a 570-millimetre barrel despite the overall weapon length of just 690 millimetres (27 in). The short length makes the weapon easier to handle in close-quarters 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. In riot conditions, for example, less-lethal flexible baton rounds can be used with standard rounds in reserve.

A possible production variant of the NS2000 has a 460-millimetre barrel in a weapon with an overall length of 560 mm (22 in). The shorter length reduces the magazine capacity to 5+5 rounds and makes the weapon easier to import or licence in some countries.

Its pump mechanism operates in a forward-back motion due to its moving-barrel mechanism, instead of the traditional moving-action. This method of operation is quite rare.

The NS2000 has been available for civilian purchase since 2003, with the majority of sales in Europe.Thanks for the post.I found those info on wiki.@upvoted and resteemed
