Best JAK Cataclysm RPK Loadout in CoD MW3 & Warzone

Season 5 brings with it a large content drop for Modern Warfare 3 and Warzone, including the arrival of two weapons earned through the Battle Pass, fast-paced modes for Multiplayer, on top of the revival of Superstore on Urzikstan for Warzone. Season 5 also brings with it additional attachments to unlock, with Week 2 unveiling the JAK Cataclysm Aftermarket Part.

The JAK Cataclysm is an Aftermarket Part available for the RPK, a Carry Forward weapon for Modern Warfare 3. This Conversion Kit essentially transforms the RPK into a.50-caliber Sniper Rifle, boosting damage and range at the cost of handling and fire rate. Here is the best loadout for the JAK Cataclysm RPK in Modern Warfare 3 and Warzone.

How To Unlock The JAK Cataclysm Aftermarket Part

The JAK Cataclysm Conversion Kit is a free reward available in Week 2 of Season 5 for Modern Warfare 3 and Warzone. To acquire it, players need to complete five of the seven Week 2 Challenges. These challenges can be completed across all modes in Modern Warfare 3 and Warzone, including Zombies, allowing players to acquire the Aftermarket Part regardless of the mode they play.

The Week 2 Challenges can be viewed via the Launcher Menu by heading over to the Challenges tab and then to the Weekly Challenges tab.

Once Season 5 has concluded, the JAK Cataclysm Aftermarket Part will become an Armory Unlock for those who have not unlocked it.

This first JAK Cataclysm RPK build is tailored for Modern Warfare 3's Core Multiplayer. Running the attachments listed below aims to boost the weapon's aim-down-sight speed and sprint-to-fire speed, along with improving aiming stability for better accuracy. Though the resulting build is still rather sluggish, keeping it from becoming one of the game's meta weapons, the fast fire rate of this weapon can provide players with consistent one-shot eliminations for some satisfying kill chains.

Best Equipment

The JAK Cataclysm for the RPK slows down the weapon considerably, resulting in reduced mobility and a slower reload speed to boot. However, these drawbacks can be mitigated. With the equipment listed below, players will benefit from increased mobility through an extended Tactical Sprint duration and refresh time, as well as improved reload speeds. Additionally, faster weapon swap speeds and undetectability by enemy UAVs are also included.

The JAK Cataclysm for the RPK is a solid option for players looking to gain consistent one-shot kills on enemies from medium-to-long-range engagements, but its slow handling is its biggest drawback for close-range scenarios. This is where a solid Handgun comes into play, one that players can swap on the fly. The WSP Stinger is currently one of the best Handguns for Season 5, as with the Akimbo rear grip, it has one of the fastest TTK of all weapons in its category.

Best JAK Cataclysm RPK Loadout For Warzone

This next JAK Cataclysm RPK is made specifically for Warzone, putting more of an emphasis on boosting damage range and bullet velocity at the cost of reduced mobility and handling. This aims to bring the weapon up to speed with other options in the long-range meta. Though this build does not necessarily compete with the likes of the KATT-AMR from a distance, it is a solid option thanks to its faster rate of fire.

Best Perk Package

At its core, the JAK Cataclysm RPK is essentially a Sniper Rifle conversion that can be significantly enhanced with the right Perk Package. The Perks listed below offer several benefits, such as reducing flinch while aiming down sights, boosting reload speed, and allowing players to replate to full armor faster. Additionally, they include visual pulses that warn the player when they are spotted by another enemy.

The JAK Cataclysm RPK is a fast-firing Sniper alternative that fits rather nicely with Warzone's large open maps. However, much like Multiplayer, it severely lacks its ability to perform well up close. Therefore, players should pair it with a weapon capable of performing well at close range. Some of the best weapons players can consider include the BP50, the Superi 46, the FJX Horus, the Striker 9, and the Static-HV.
