The RMB-93 shotgun from Russia has peaked my interest, but I have been unable to find any diagrams relating to its operation. Any resources on the inner workings of this beasty would be welcome.

On a separate note, I am playing around with plastic and 3D models of a new shotgun action that was inspired by both that weapon and the South African Neostead. The objective is high capacity with very little receiver length behind the shell; ideally less than 2.5 inches, allowing a longer barrel length for overall size.
I have my own idea how to accomplish this, but if there is a different solution, I would love to see it.
