The feeding tube is placed over the barrel rather than under it, and is accessed through a flip-up cover on the top of the receiver. Once the weapon is loaded, a shell is chambered by pushing the slide forward-then-backward, instead of the standard backward-then-forward motion of the forend found on most

weapons. Having the RMb-93 a fixed breech face and movable barrel, the operation moves the entire barrel assembly. Once a round is fired and another is chambered, the empty shell falls downwards to the ground, pushed by its own weight. The design of the RMb-93 "Rys-K" carries several advantages: the ejection system makes the gun fully ambidextrous, and the magazine located over the barrel gives the shotgun a low

and reduces upward recoil. The main drawback of the overall design stands in the fact that the weapon has a pistol grip with upfolding metal stock, which when folded finds itself right up the feeding tube. The RMb-93 thus can not be reloaded without extending or removing the stock, a disadvantage if it is being used tactically with a folded stock.

Variants and commercial availability

The RMb-93 "Rys-K" shotgun is commercially available to civilians in Canada, Russia, Italy and possibly in other Countries. For the civilian distribution in Russia and Canada, the shotgun is provided with a stock disconnector that prevents it from firing if the stock is not extended, so to comply with local laws and regulation about the minimum legal length for civilian firearms. Additionally, KBP manufactures several variants of the "Rys" shotgun series for the civilian distribution. The RMb-93 "Rys-K" itself is manufactured with Phosphatized finish to resist salt corrosion (for use in maritime environments). The RMO-93 ''"Rys"'' is a purely sporting variant with wooden thumbhole stock and either wooden or synthetic slide-forend; very similar to it is the ''"Rys-OT"'' variant with longer barrel, synthetic or wooden slide-forend and standard wooden shotgun stock. The RMF-93 ''"Rys-F"'' shotgun is a longer-barrel variant of the RMb-93 "Rys-K", plus equipped with the above-mentioned stock disconnector.
