The Neostead is a manually operated, pump action shotgun with some rare (if not unique) characteristics. First of all, Neostead is built using fixed breech face and movable barrel. Assuming that the barrel is loaded with empty case, to reload the gun one must pull the slide forward, and then - backward. This will cause the barrel to go forward, leaving the spent case held against the breech face by the extractor. When barrel will clear the spent case, it will be ejected down through the opening in the gun shell. When slide is pulled all the way forward, the fresh cartridge is released and pushed back out of the magazine above the barrel, and then lowered by the feed ramp until it is aligned with the barrel and put against the breech face simultaneously. When the slide is pulled backward, it will take the barrel back, so the barrel will enclose the cartridge and finally lock itself to the fixed breech face. Now gun can be fired again by pressing the trigger. The only one other mass produced shotgun with forward-moving barrel and a fixed breech face is the Russian RMB-93 shotgun.
