The fourth week ofCall of Duty: Modern Warfare 3’sfifth season has added a new aftermarket part for players to earn. Named the JAK Protean, this turns the RAAL LMG into a strange hybrid between a light machine gun and a marskman rifle, capable of sniping enemies from a distance with a simple change in fire mode.
But as with all aftermarket parts, you’ll need to unlock it first. Completing any five of this week’s challenges—including challenges for Multiplayer, MWZ, and Warzone—will unlock this kit. Before we explain how to complete all of this week’s challenges, let’s first cover how the JAK Protean Kit works to see if unlocking it is worth the hassle.
Week 4 Challenge Reward
After completing any five of this week’s challenges, you’ll unlock theJAK Protean for the RAAL LMG,a weapon originally unlocked in MW2. This kit slightly lowers the damage of the RAAL’s full-auto mode in exchange for a substantially stronger semi-auto mode, one that rivals most marksman rifles.While in semi-auto, this gun is a two-tap from the lower torso and up.From our testing, this extends well past 50 meters with no added attachments.
The JAK Protean Kit restricts your barrel and underbarrel options. It also comes with a free hybrid optic, although this can be changed to any optic you please.
You ideally want to use this kit in semi-auto, as the full-auto mode is worse than most LMGs and MW3 assault rifles.Since semi-auto is so accurate, you can comfortably build this kit around ADS speed and mobility,which turns the weapon into a two-tapping battle rifle. With the right attachments, you can lower the gun’s ADS speed to a respectable 260ms, the same as most assault rifles.
