A reskin of the aimpoint to make it look like an arrow incase you like that sort of thing.
Now you can select between a green thick visible one or a thin realistic acog style red one.
How? Just click the folder of your choice then place the appropriate materials folder then place it in "Steam/steamapps/yourname/insurgency/insurgency"

and its called an acog scope.
