Because the G11 uses caseless ammunition there are no extraction and ejection steps. Even though the rotary chamber does not lock up in the true sense of the word, the fact that it has to rotate in and out of alignment with the barrel means that the G11 can be considered to have a lock/unlock phase. If a round fails to fire or the weapon is being used with training rounds, the rifle can be manually unloaded by twisting the cocking handle counterclockwise. This pushes the failed/training round out an emergency ejection port on the bottom of the rifle and loads the next round.
