ATOG scopes iron sight does not work at all with M4 and with MP5 and UMP it works partially.

ATOG scope has iron sight on top of the scope but when using M4 and trying to switch optics from glass to iron nothing happens.

When using MP5 or UMP switching from glass to iron the view point does not use the iron sight on top of the scope but instead it uses weapons own iron sight using small cracks in the bottom of the scope. This is madness as it severely hinders users visibility and situational awareness as the scopes body blocks half your screen.
