Tyrant King
It’s hard to gage as the video is clearly playing with speeding up and slowing down. However a number of rifles use an intentionally reduced rate of cycling to increase control. SAR21 for example and some modifications to the AR15 family particularly FERFRANS rate reduction system. If you can drop the rate of fire the weapon is still able to pin down its targets but much more able to be retained on target and it’s easier to train infantry to do so as you don’t need to keep them on the range as long burning through as much ammo.
