How to unlock the JAK Slash in MW3 and Warzone

Aftermarket Parts are undoubtedly one of the best new features added to Call of Duty in quite some time.

Modern Warfare 3‘s weekly additions to the game can sometimes change a gun completely, but others are just fun or useful attachments that can go on a variety of guns. This week’s part is the latter, and it’s a very interesting one to try out.

Here’s everything to know about the newest Aftermarket Part in MW3 and Warzone and how to get it.

What is the JAK Slash in MW3 and Warzone?

The JAK Slash is an Aftermarket Part in MW3 and Warzone. It’s an underbarrel vertical grip that doubles as a combat knife, offering the ability to melee faster and more lethally while using a gun that can equip it. It works on many assault rifles, SMGs, and battle rifles in the game.

This is truly one of the more unique attachments added as part of the Aftermarket Parts feature in MW3. It’s original and pretty cool, but its usefulness is up to each player to decide on the online battlefield.
