13/4/24 I had originally planned to turn this into some kind of airsoft replica but the internals are so cramped that the only really options were stuffing a hacked up AEG gearbox in there, or a HPA engine; didn't really like either option so instead I pivoted to turning this into a cosplay type of prop replica. As-is it's quite accurate to the real-life XM556 Micro Gun, a mini-minigun essentially- the overall size is correct, though the proportions of the dummy motor and de-linker mechanism are a bit off, and there is a large hole in either side of the main body for the original foam dart ammo belt. Still, it looks the part and is a solid base for this project, just needs some cosmetic work and a paint job, so here we go then...
