I believe the iron sight should match the crosshair when you toggle in and out, seems to be below the crosshair for some reason.
This is .63 single player
im having same issue
I can confirm this issue. I would also add that some action must break the alignment (between the crosshair and the ironsight) because when you start a fresh game both are lined up.
Hello dokkey and thank you for the report.
We have confirmed the issue and it has been scheduled for a fix.
