The '''RMb-93''' is a pump-action [[shotgun]] designed and manufactured by the [[KBP Instrument Design Bureau]] of [[Tula, Russia]]. It is the baseline model of the ''Rys'' ("[[Lynx]]") series of shotguns, taking the model name of '''Rys-K'''. The RMb-93 has been conceived as a combat weapon for [[Special Forces]] and [[Police]] units that might face [[Close Quarters Battle]] situations. The weapon was engineered to reduce the size as much as possible.

== Description ==
The working system of the RMb-93 is itself an odd slide-action operation called "Inverted Cycle", similar in concept to the one used in the [[South Africa|South-African]] [[Truvelo Armoury]] [[Neostead]] shotgun (the only other mass-produced firearm to be based upon this system).  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 [[pump-action]] 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 [[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 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 overall 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 [[Parkerizing|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 has a longer barrel, with either a synthetic or wooden sliding-forend, and standard wooden shotgun stock.

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.
