Season 5 of Modern Warfare 3 and Warzone introduced a variety of additional content, including neat additions to the meta like the STG44 and the return of fan-favorite locations such as Superstore. However, not all content is tied directly to the season's launch, as Week 4 brings the arrival of an additional Aftermarket Part.

The JAK Protean Kit is an Aftermarket Part available for the RAAL MG, one of the many Carry Forward weapons in Modern Warfare 3. This nifty Conversion Kit provides an alternative firing mode for the weapon, along with boosting attributes such as damage range, bullet velocity, and recoil control. While handling attributes and headshot damage do take a hit, this Conversion Kit does boost the weapon to the point where it can be viable in certain situations.

Best JAK Protean RAAL MG Loadout For Modern Warfare 3

This loadout is designed to significantly boost mobility and handling — two important factors for the fast-paced action in Modern Warfare 3 Multiplayer. While recoil control is reduced, the key to making the JAK Protean RAAL MG viable is to switch the weapon to semi-auto mode. Doing so allows for a consistent two-shot kill and, in some cases, a single headshot kill, effectively turning the weapon into a Marksman Rifle with the added benefit of a large magazine.

Best Equipment

Despite our best efforts, the RAAL MG remains one of the slowest weapons in Modern Warfare 3, especially in terms of movement speed. Fortunately, players can equip gear that enhances movement speed and extends Tactical Sprint duration, such as the Infantry Vest and Lightweight Boots. To further mitigate the weapon's slow handling, players can use additional equipment that boosts weapon-swap speed and reload times. Here's a breakdown of the best Equipment Package for the JAK Protean RAAL MG:

  • Infantry Vest (Vest)
  • Quick-Grip Gloves (Gloves)
  • Lightweight Boots (Boots)
  • Mag Holster (Gear)

While the JAK Protean Kit for the RAAL MG offers a powerful weapon capable of eliminating Operators in just two shots, its slow reload speed and sluggish handling can be a drawback in intense gunfights. This is where a quick swap to a secondary weapon comes into play, with the WSP Stinger being one of the top-recommended options for Season 5.

This next loadout is tailored specifically for Warzone. While some attachments have been carried over from the previous setup, the focus here falls more toward improving recoil and gun-kick control. Again. The recoil in full-auto mode can be hard to control, but the JAK Protean Kit for the RAAL MG proves pretty efficient in single-fire mode, making it a viable alternative to weapons like the MTZ Interceptor. This setup essentially converts the RAAL MG into a strong, albeit slightly more sluggish, Marksman Rifle alternative.

Best Perk Package

Much like in Multiplayer, the RAAL MG significantly reduces player movement speed, and even with a smaller magazine attachment, the reload speed still falls on the slow side. To counter these drawbacks, players can equip Perks that boost both attributes, such as Double Time for increased mobility and Sleight of Hand for faster reloads. Additionally, meta Perks like Tempered and Birdseye can be equipped to help players replate to full armor quicker, along with detecting Ghosted players on the minimap when using a UAV.

The RAAL MG equipped with the JAK Protean Kit is a strong contender in the medium-to-long-range meta when it comes to Warzone Battle Royale. However, its slow draw time, partnered with its reliance on accuracy when using it in semi-auto mode, can make it challenging to use in close-range gunfights. This is where a close-range support weapon can help, with Submachine Guns being the most viable option. The top picks for the SMG category for Season 5 include the Static-HV, the FJX Horus, and the Superi 46.
