Kill Counter

The Kill Counter is a piece of customization in Call of Duty: Black Ops III. The feature is unlocked after prestiging one's weapon. Thereafter, the kill counter will appear on the left side of the player's gun, and will kill keep track of the player's kill count with said weapon. The kill counter starts before the player unlocks the gun (if the player picks up a weapon or uses it in gun game before unlocking it, kills with the gun will still count).
