Battlefield 4 fixed it. Turns out, in most shooters the bullet actually comes out of the center of the player's forehead, not so much the muzzle of their weapon. DICE realized that this was pretty frustrating, but also realized that getting your scope over a ledge and firing, but your bullet hitting the object your hiding behind may be frustrating as well. Well DICE decided to lower where the bullet comes from to force players to expose more of their body in order to not shoot the object they are trying to headglitch behind. It took a little getting used to, because now that the bullet was coming out below the scope I had ended up shooting the wall a few times. Now the muzzle of your weapon has to clear the object in front of you. Many people could learn from this development decision.
