Just a quick showcase video showing all the reload animations for most of the weapons available in the Call of Duty : Black Ops Campaign, Multiplayer and Zombie modes (missing a couple of zombie DLC weapons and the Peacekeeper DLC weapon).
I don't have a single DLC/Black Market Weapon for Black Ops 3 and 4, so don't bother asking for a video for them, i won't make a video for them when i'm missing half of the weapons.
