How to unlock JAK Protean Aftermarket Part in MW3 and Warzone

We have made a practical guide where we explain how to unlock JAK Protean Aftermarket part in MW3 and Warzone.

Now available in MW3 and Warzone through the Season 5 Week 4 challenges, the JAK Protean aftermarket part, a conversion kit of a kind for the RAAL MG LLMG, is here. This absurdly oversized upgrade makes this formerly dominant LMG competitive again, if not outright fearsome, in modern times. The Protean, with its enormous increase in fire rate and the addition of a telescoping barrel, makes the RAAL MG much more adaptable, allowing players to succeed in far more combat scenarios. With this faster rate of fire, recoil is sure to be increased, making the weapon arguably worse at range. However, large damage output and generous magazine capacity balance out this penalty. Additionally, the surprising effectiveness with which a Protean can take care of close-quarters engagements adds a lot of tactical versatility on top of the RAAL MG, which is already potent.

This conversion kit makes for an enticing option for players looking for a high-damage, high-fire-rate LMG to dominate both long-range and close-quarters engagements.

Boost your gameplay with this powerful JAK Protean Aftermarket Kit for RAAL MG LMG in Call of Duty: Modern Warfare 3 and Warzone. Grind hard to get through the challenges for Season 5, Week 4. Every Wednesday, players face a fresh set of seven objectives on Multiplayer, Zombies, and Warzone. Although the overall challenge count tops out at a lung-busting 21, the good news is that players only need to complete a mere five challenges from any of these modes to receive the coveted JAK Protean part. Basically, what this means is that players can opt for the game mode in which they are best or most comfortable—the intense multiplayer action, the undead hordes of Zombies, or the vast battleground of Warzone.

MW3 Multiplayer Season 5 Week 4 Challenges



The Modern Warfare 3 multiplayer Season 5 Week 4 challenges are oriented toward particular combat tactics and weapon mastery. As a result, you will have to alter your style of play to effectively complete these objectives.
  • Low-profile eliminations: Take out 20 enemies while prone; this speaks to creeping up and then surprising your opponents.
  • Precision kills: This requires much more careful aiming and controlled trigger discipline to achieve 25 kills using a weapon in single-fire mode.
  • Assault Rifle efficiency: Showing mastery of Assault Rifles, thereby bagging 10 double kills without reloading, the importance lies in fast reactions with accurate follow-up shots.
  • Long-range prowess: Using Marksman Rifles or Sniper Rifles, players must eliminate two enemies with a single magazine on five separate occasions. This requires precision and situation awareness. Aggressive SMG play: The challenge of eliminating 30 opponents while moving, with a Submachine Gun, encourages aggressive and fast-moving game play that rewards mobility and rapid fire accuracy.
  • Shotgun Dominance: 12 one-shot kills using a Shotgun acts as proof to be close enough to the fight and unleash devastating damage in an instant. Mounted Weapon Mastery: A total of eight enemies must be destroyed with mounted weapons as proof that one holds important positions with suppressive capability.

Objective-Based Challenges


  • Marksman Mastery: Get a kill count of 300 by using iron sights for accuracy.
  • Long-Range Eliminator: Eliminate 150 enemies using a scoped weapon.
  • Heavy Weapon Mastery: Cut loose with an upgraded machine gun and get 300 kills.
  • Sniper Specialist: Be an exceptional sniper and get 10 kills without taking 20 hits.
  • Silent Operative: Employ measured elimination of 100 enemies using the suppressed assault rifle.
  • Critical Expert: Excel at critical hits by landing 200 critical shots with a sniper rifle or marksman rifle.
  • Attachment Advantage: Five attachments equipped and 75 kills with your machine gun


Notably, it is in these challenges that the tests will be into the domains of skills, strategy, and weapon skills.

Challenges available in Loot Cache


  • Northwest Foray: Uncover 20 hidden loot caches within Urzikstan's northwestern expanse. These include the Resort, Power Plant, Seaport, and Cargo—some of the hottest drop zones.
  • Southern Scavenge: Operators must search and open 20 loot caches in the southern part of Urzikstan, containing the bustling City, suburban Suburbs, and opulent Manor.
  • Eastern Expedition: Adventurous players are tasked with exploring the eastern sector of Urzikstan to discover and open 20 loot caches within the expansive Military Base and surrounding Farms.
  • Central Collection: Players will need to search the center of Urzikstan, namely Old Town and Low Town, for a total of 20 loot caches.


Challenges in Survival and Combat



  • Top Tier Triumphs: Prove skill and strategy through a top 10 finish in five different Warzone matches.
  • Weaponized Wins: Contribute 10 eliminations on enemies by using a recommended weapon; either kills or assists count.
  • Contract Completion: To complete this challenge, players will have to finish 15 various contracts in a few matches of Warzone.


It seems like getting the JAK- Protean aftermarket part will be a smooth sail this week as all the challenges from Multiplayer to Zombies to Warzone are quite achievable. While the objectives given by the Zombies mode are pretty simple in their nature, for all five objectives players will have to go through multiple infiltrations and exfiltrations which can drag on playtime.


Multiplayer fans will feel very familiar with standard kill challenges peppered across a wide array of weapon categories. These will be easily completed within a few matches if players are efficient. Warzone offers a much-needed respite from the kill-centric challenge of last week. Players will need to find and open loot caches located in different areas of the Urzikstan map, and this will no doubt prove much easier to complete.


Now that you know how to unlock the JAK Protean Aftermarket part in MW3 and Warzone, you can apply our guide and complete the indicated challenges.
