The JAK Decimator is an Aftermarket Part released during Season 4 for Call of Duty: Modern Warfare 3 and Warzone that changes the Lachmann Shroud submachine gun into a full-auto weapon. Here is how to get the JAK Decimator in MW3 and Warzone.
How to Unlock JAK Decimator in MW3 and Warzone
Modern Warfare 3 and Warzone players can unlock the JAK Decimator Aftermarket Part by reaching max level with the Lachmann Shroud and getting 30 Operator silenced kills with SMGs. That means any submachine gun with a suppressor muzzle attached to it against other human players.
The 30 kills can be done in MW3 competitive multiplayer and Warzone game modes, as long as the gun is suppressed and you do not appear on the mini-map when fired. It can also be done with any SMG in the game, even if it is not a recommended weapon at the time.
The challenge for the JAK Decimator is much different than the requirements for the other Aftermarket Parts. For example, the recently added JAK Harbinger Kit for the M4 assault rifle required players to complete five weekly challenges.
In fact, you may have already unlocked the new attachment without even realizing it. Simply go to the Lachmann Shroud weapon under the SMG tab in loadouts, and the JAK Decimator will be found under Conversion Kit in Gunsmith.
How to Unlock Lachmann Shroud in MW3 and Warzone
The Lachmann Shroud submachine gun is actually a weapon first introduced in Modern Warfare 2. All players who own Call of Duty: Modern Warfare 2 will already have the weapon unlocked in Modern Warfare 3 as long as it was unlocked in the previous game.
Those who did not have the previous game can get some weapons via challenges or by extracting the weapon from the Zombies mode in MW3. It can be found randomly in caches or you can have another player drop the weapon for you.
