Here are some screenshots of what Hipfire Accuracy does:
Just to note, these cross hairs are at a static position. When walking they expand out further and when running they disappear.
Some other guns might have the top vertical line removed as some guns are different that way.
IMHO they should really just keep the ON as a default, hell just make them plain white dots in the center of the screen like in other shooter/3rd person games.
To me when you add ps/xbox controller types, you get into problems of movement.
These crosshair traits just add to an already complex loadout. None of this is explained with words in the game.
