The JAK Slash is now available in MW3 and Warzone, providing a new underbarrel attachment that players can unlock to give their weapons more utility.
Following on from the JAK Widemouth Barrel and JAK Cataclysm, the JAK Slash is the third Aftermarket Part added in Season 5.
While the others were conversion kits that fundamentally changed their respective weapons, this is instead an underbarrel attachment that can be used on most primary guns. That includes assault rifles, battle rifles, LMGs, Marksman Rifles, and even some Sniper Rifles.
When equipped, it converts gun melee attacks into knife swings, similar to when a Throwing Knife is used. Also, this attachment boosts key mobility stats like sprint speed and movement speed, making it truly unique and perfect for fast-paced playstyles.

How to get the JAK Slash underbarrel attachment
The JAK Slash is unlocked by completing any five weekly challenges from Season 5, Week 3. These challenges can be completed across multiplayer, Warzone, and Zombies, or even a combination of the three.
After you have finished five challenges and unlocked the JAK Slash, the Aftermarket Part can be equipped on most primary weapons in the underbarrel attachment section of the gunsmith. Unlike most other AMPs, the JAK Slash does not require a gun to be fully leveled before it can be equipped.
