The RMb-93 has been conceived as a combat weapon for Special Forces and Police units that might face Close Quarters Battle situations.

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 center of mass 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 "Rys-K" shotgun is commercially available to civilians in Canada, Russia, Italy, and possibly in other Countries.

The RMF-93 "Rys-F" shotgun is a longer-barreled variant of the RMb-93 "Rys-K", plus equipped with the above-mentioned stock disconnector.
