What does this thing do
There's just this random block on top and I have no idea what its for
EDIT: People keep saying its a charging handle but the charging handle in question is literally on the ejection port. I have a 3D printed Morita at home and that's clearly what its supposed to be.
EDIT 2: Alright I guess it really is the charging handle. Sorry for the confusion but thanks for clearing it up.
