For general parts nomenclature, refer to Figure 1.

After full rearward travel, the bolt assembly returns forward, picking up a new shell from the magazine and chambering it automatically. After the last shell has been fired, the bolt assembly locks to the rear, instead of returning forward. This facilitates speedy reloading. The short-stroke of the gas piston along with the snug, gas sealing fit of the piston rod limits the amount of 8
