The bolt carrier that was pushed back is restored by the recoil spring, and the next round bullet is pushed from the banana magazine to the chamber (because the bolt is pushed no less than 1 cartridgebullet length backwards, enough space is created and the next roundbullet is pushed up into it).
At the end of all the hard work, when the gas operated system ran smoothly, I yelled out in excitement.
The other thing that I want to compliment myself on is the included switch that goes between "safety", "full automatic", and "semi automatic" modes.
When the safety selector is set to on, the selector lever blocks the trigger so it couldn't be moved.
In semi-automatic mode, the selector lever doesn't do anything.
