Engineer Alexander G. Bandaevskiy developed the Zlatoust RB-12 "Bandaevskogo" pump-action shotgun of Armenian origin in 1995. The weapon was chambered for 12-gauge shells and fired from a six-round detachable box magazine. The weapon was unique in its action for the bolt was fixed with the barrel designed to move. The slide action actually involved movement of the slide and barrel sections as a whole unit when introducing a new shell and clearing spent shell cases. Sighting was accomplished through a pair of iron installations - one set over the barrel and the other over the receiver. A carrying handle, a feature most shotguns usually lack, was also worked in. The rifle-style shoulder stock was hinged to fold over the side of the receiver and spring-loaded in such a way as to allow the firer to make the weapon ready to fire within seconds of being unloaded from its carrying bag. A skeletal stock was also designed for lightweight functionality. Loops at the front and the rear allowed for use of a shoulder strap. Overall length was 825mm and 610mm with the stock folded over. The barrel measured 525mm long.

Outwardly, the weapon was given a rather boxy, workmanlike appearance. The barrel protruded a distance away from the front of the receiver to which the slide grip was featured. The weapon was given a traditional pistol grip near a conventional trigger unit. Ahead of this was the well for the straight box magazine. While primarily firing from the box magazine, the RB-12 could also be fed individual shells through the open breech as needed (with the slide and barrel sections pulled fully open). The RB-12's action also proved highly robust and able to fire even after having been exposed to sand, dirt and debris during testing. Recoil was as expected considering the 12-guage shell being fired.

It is believed that only about 50 units of the RB-12 were ever produced, their quality and reliability not comparable to top-flight shotgun systems already on the market. The weapon has generally faded from public interest since.
