Modern Warfare 3 Season 5 Week 4 marks the addition of the JAK Protean kit for the RAAL MG light machine gun. As is tradition, you can’t use this aftermarket part right away as you must finish certain quests first in order to unlock it.

With that said, here’s all you need to know about obtaining the JAK Protean Kit in Modern Warfare 3 and Warzone.

Here’s how to unlock the JAK Protean Kit aftermarket part in MW3 and WZ
