MW3 and Warzone: How to Unlock the JAK Voltstorm

A new aftermarket part for the MW3 and Warzone Stormender is available to unlock which goes by the name of the JAK Voltstorm. When firing, it discharges deadly bolts of high-voltage electricity capable of hitting numerous targets. The best part is that it can be used against Operators, not just enemy killstreaks.

To add the Conversion Kit to your arsenal, you must complete any five of the Week 4 challenges listed in this guide.
