The JAK Purifier Aftermarket Part was added to Call of Duty: Modern Warfare 3 during Season 1 and requires players to unlock it before it can be equipped. Here is how to unlock the JAK Purifier to use in Modern Warfare 3.
How to Get the JAK Purifier in MW3
The JAK Purifier Aftermarket Part can be unlocked by progressing through the MW3 Season 1 Battle Pass. Players will earn XP for the Battle Pass by playing in any of the modes for MW3 multiplayer, MW3 Zombies, and Warzone battle royale.
The Aftermarket Part is located in sector A14 of the Season 1 Battle Pass. It is the fifth reward of the sector, meaning that players will have to unlock the other four rewards within the sector before the part can be unlocked.
The JAK Purifier is a free reward in the Battle Pass, so players do not have to purchase the Season 1 Battle Pass to get it. There are multiple paths to get to sector A14, but the most efficient path will require 30 battle tokens before it can be unlocked. Make sure to set auto-unlock rewards to off in the lower right corner of the Battle Pass menu to set your own path, instead of the game choosing for you.
How to Equip the JAK Purifier in MW3
The JAK Purifier Aftermarket Part is a flamethrower underbarrel attachment for assault rifles and battle rifles. It can be equipped on any of those types of guns, so long as you have leveled the weapon up to start equipping underbarrel attachments.
The flamethrower has a limited amount of ammo per life with no other pro perks for the weapon. The flamethrower attachment cannot be reloaded and will increase Aim Down Sight Speed, making it slower to bring the weapon to your face for aiming.
