Figured I’d share this in light of the recent video on the topic (Link to 10:17 video).

The RMB-93 is a 12g pump action that has it’s magazine tube above the barrel to allow the user to load it while visually seeing the gate to make it easier to reload. It weighed roughly 5.5lbs (2.5 kgs)

A few versions were made including a sporting model featuring a thumbhole stock.
