Aftermarket Parts are special attachments that can change weapons entirely, and if you’d like to change the burst-fire M16 into a fully automatic assault rifle, you’ll need to know how to unlock Warzone and MW3‘s JAK Patriot.
May 15’s Call of Duty patch not only nerfed the overpowered Tonfa stick, but also introduced another new Aftermarket Part as Season 3 Reloaded rumbles on to its conclusion.
Unfortunately, the JAK Patriot won’t just be added to your inventory, and you’ll need to put in some work to get your hands on it. Thankfully, I can explain the process to you to try and help you unlock it as quickly as possible.
