How to unlock JAK Protean Aftermarket Part in MW3 and Warzone

The JAK Protean Aftermarket Part is now available in MW3 and Warzone as part of the Season 5 Week 4 challenges. This new conversion kit is exclusively for the RAAL MG LMG, a classic weapon from MW2. With this AMP, the RAAL MG, which had lost its prominence in MW3 and Warzone, could once again become a formidable weapon.

The conversion offers a faster fire rate and a telescoping barrel, making it adaptable for various gunfights. Although the weapon's recoil pattern will require careful control, particularly at long range, its high damage output and large magazine size offer strong compensatory advantages. Additionally, the increased fire rate makes it viable for close-range engagements when necessary.

That being said, this article explains how to unlock the JAK Protean Aftermarket Part in MW3 and Warzone.

Acquiring the JAK Protean Aftermarket Part should be easy this week, as the challenges are straightforward across all modes, whether you're playing MW3 Multiplayer, MW3 Zombies, or Warzone. While the MWZ tasks are simple, they may consume some time since you’ll need to infil and exfil the region multiple times to complete all five objectives.

In MW3 Multiplayer, you simply need to rack up kills using different weapon categories under various criteria, which can be accomplished within a few matches.

In Warzone, unlike last week’s challenge that required gathering kills, this time, you’ll need to open loot caches in different regions of Urzikstan, making it easily achievable.
