No, that's normal operation, the nozzle never rests at the full forward position after every shot. It's a hop up issue, trust me, I've fixed at least a dozen of these over the years, always the same problem, hop up.

See, the way the system allowsonly one BB to be loaded and shot every time is the hop up nub, the thing that puts the back spin on the BB. It sticks into the barrel, the nozzle pulls back and one BB is let into the chamber and sticks there, the nozzle pushes forward, the next BB in line gets pressed down into the magazine, the nozzle sits full forward and the piston is released, pushing the BB out of the barrel. If the one BB amount of space between the BB feed and the hop up nub is increased to the space that will allow 2-3 BBs to enter, then they will. And the only thing that can allow that space to occur is the weak link, the hop up/inner barrel securing parts. That is the problem you have.
