How to unlock the JAK Voltstorm in MW3 and Warzone

The sad day has finally arrived. The final new Aftermarket Part in Modern Warfare 3, the JAK Voltstorm, is here.

One of the best new features added to Call of Duty in recent memory, Aftermarket Parts will be remembered fondly by players. For most of the weekly updates throughout MW3’s live service campaign, Aftermarket Parts have been made available to unlock, sometimes completely changing a gun’s appearance and performance.

This final part is a Conversion Kit transforming a weapon that is otherwise useless for getting kills and turns it into something fun for the final few weeks of MW3’s live service era—before the calendar flips to Black Ops 6 and a new CoD grind begins. Death, taxes, and a new CoD game means that MW3’s fun additions must come to an end, as everything shifts over to Treyarch and players get to see what the studio has to offer the series.

Here’s everything there is to know about the JAK Voltstorm and how to get it in MW3 and Warzone.

What is the JAK Voltstorm in MW3 and Warzone?

The JAK Voltstorm is an Aftermarket Part and Conversion Kit for the Stormender in MW3 and Warzone. It utilizes “high-voltage electricity” that “is cycled through copper coils and discharged in a lethal bolt capable of hitting multiple targets,” according to its description.

The Stormender on its own is incapable of dealing lethal damage, instead used for destroying killstreaks and air support or hitting enemies with a jolt that EMPs them. With this part, however, it can be used to kill foes at extremely close range.

How to get the JAK Voltstorm in MW3 and Warzone

To unlock the JAK Voltstorm, players need to complete any five challenges during season six, week three of MW3. Any five challenges can be completed in any combination from MW3 multiplayer, Warzone, or MW3 Zombies.
