High Caliber

High Caliber is an attachment featured in Call of Duty: Black Ops III, Call of Duty: WWII, and Call of Duty: Black Ops 4 and Call of Duty: Mobile that increases headshot damage.
__TOC__
==Call of Duty: Black Ops III==
It can only be attached on Pistols or Assault Rifles, and increases the headshot damage multiplier of any gun it's attached to from 1.1 to 1.5, except on the Sheiva and MX Garand.
These two weapons are two of the guns that get the most benefit from the attachment, as it changes the guns from a two shot kill to a one shot headshot. This is achieved thanks to the unique increase both weapons gain, a 1.8 headshot multiplier (if they got a 1.5 multiplier, the attachment would make no difference).
It is a more effective attachment for Burst Fire and high-recoil weapons. Burst fire weapons greatly benefit if any of the three or four rounds hit the head of the opponent, and high-recoil weapons will direct their rounds upwards and towards the head, meaning the last of the shots fired are more likely to guarantee a kill.
==Call of Duty: WWII==
High Caliber returns in Call of Duty: WWII, performing similarly if not identically to its Black Ops III iteration. However on the M1 Garand, SVT-40 and M1911 it only effectively works on headshots that are above the range of the 2-shot kills in multiplayer. It also has no effect on the M1941's 5-shot effective kill range in multiplayer.
==Call of Duty: Black Ops 4==
High Caliber returns in Call of Duty: Black Ops 4, where it raises the headshot damage multiplier to 1.5x as seen in past games. High Caliber is available on most assault rifles, sniper rifles, and pistols. Equipping High Caliber also gives the player the option to equip a variant known as High Caliber II, which increases damage to the upper chest, and to the torso on sniper rifles only.
==Call of Duty: Mobile==
The High Caliber returns in Call of Duty: Mobile, where it is split into two ammunition attachments, namely Large Caliber Ammo and Large Caliber Ammo A.
===Large Caliber Ammo===
The attachment is available to the HVK-30 assault rifle and MX9 submachine gun. Despite the same name, it affects both weapons differently.
===Large Caliber Ammo A===
The attachment is available to the PP19 Bizon submachine gun.
It helps by improving the legs multiplier to 1x from 0.8x, effectively leaving room for error. In addition, it increases enemy's flinch upon hitting them, in exchange of weakened wall-penetrated damage.
