The H5A shoots from the magazine. Air pressure launches the pellet from the magazine and into the barrel, transiting the breech. On completion of the shot, a spring moves the magazine so that the next chamber lines up ready for the next shot. The magazine is restrained from moving by a small pawl which engages with a notch in the underside. Air pressure releases this pawl momentarily allowing the magazine to index one position.
