That was essentially the kind of magazine I was talking about. I wouldn't really call it a box magazine though. The benefit of having a breakback system with the magazine kept within the gun is that it would allow for maintaining the center of balance even without the magazine, thus making it more effective in those melee situations where there is no mag or it is empty.
