There were far simpler caseless mechanisms devised. But the G11 fired caseless ammo, rotated it 90 degrees and more importantly had a burst mode where the barrel and magazine recoiled together continually throughout the 3 round burst, only returning to battery after the 3rd round was fired. That latter one added a lot of complexity.
I wonder if the G11’s mechanism is so overengineered because it uses caseless cartridges.
