MCH uses its lunchbox for some of the other abilities that don’t necessarily involve shooting so we would be left with some awkward animations where we’re interacting with a device that doesn’t exist anymore.

Another thing of note is that gunbreaker gunblades don’t actually shoot bullets. You pull the trigger and expend a cartridge to create an effect or magically enhance a strike. Even the long-range attack for GNB has you swing an arc of magical energy at the enemy rather than a bullet.
