Best M4 JAK Harbinger Loadout in CoD MW3 & Warzone (2024)

The debut of Season 4 for Modern Warfare 3 and Warzone brings additional maps and modes for Multiplayer, the DNA Bomb Killstreak, developments to the bunkers on Urzikstan, and revamps to Warzone's Gulag. Though a Battle Pass featuring three additional weapons has also provided players with alternative armaments to add to their loadouts, the Week 1 Challenges also allow players to acquire the JAK Harbinger aftermarket part for the M4.

The JAK Harbinger Kit is an aftermarket part for the M4 Assault Rifle in Modern Warfare 3 and Warzone. Equipping this conversion kit provides a significant increase in overall damage at the expense of fire rate, recoil control, accuracy, mobility, and handling. Though using this kit results in serious weapon kick, this can be mitigated with the best attachments. Here is the best JAK Harbinger M4 loadout in Modern Warfare 3 and Warzone.

How To Unlock The JAK Harbinger Aftermarket Part

The JAK Harbinger Aftermarket Part is a free reward tied to the Week 1 Challenges for Modern Warfare 3 and Warzone. To unlock it, players need to complete 5 out of the 7 Week 1 Challenges in either Multiplayer, Zombies, or Battle Royale. To find the Week 1 Challenges, players can head to the Challenges Tab via the Launcher Menu.

Best MW3 M4 JAK Harbinger Loadout

The below M4 JAK Harbinger build is made specifically with Modern Warfare 3's Multiplayer in mind, with an emphasis on keeping mobility and handling close to baseline levels. Along with improved aim-down-sight speed and sprint-to-fire speeds, accuracy and damage are also increased. Though far from the best weapon in Modern Warfare 3, this build does provide players with the means to quickly engage in gunfights, along with eliminating players with a reliable two-shot kill on opponents.

• JAK Harbinger Kit (Aftermarket Part)
• SL Skeletal Vertical Grip (Underbarrel)
• FSS OLE-V Laser (Laser)
• MK. 3 Reflector (Optic)
• Sakin ZX Grip (Rear Grip)

Best Equipment

• Infantry Vest (Vest) - Increases the duration of the player's Tac Sprint along with reducing the refresh time. Perfect for players looking to stay quick on their feet in Multiplayer.
• Scavenger Gloves (Gloves) - Provides players with the means to recover all lost ammunition from eliminated players. Serves as a great counter for the low ammo reserve of the JAK Harbinger Kit.
• Stalker Boots (Boots) - Provides both a boost in the player's strafe speed and ADS movement, great for side strafing while maintaining accuracy.
• Mag Holster (Gear) - Boosts the player's reload speed. Just like the Scavenger Gloves, it synergizes well with the JAK Harbinger Kit's low magazine size and ammo reserve.

Recommended Secondary

Though the JAK Harbinger Kit for the M4 provides players with a high-damage weapon for Multiplayer, the low magazine size and ammo reserve do limit it quite a lot. This calls for players to equip a reliable Secondary to swap to when they are unable to reload. Weapons from the Handgun category will do the trick, with some of the top picks including the WSP Stinger, the TYR, and the Renetti.

Best Warzone M4 JAK Harbinger Loadout

The below M4 JAK Harbinger build is created to be viable for Warzone Battle Royale. Running the attachments below boosts damage along with range, all while keeping accuracy close to baseline levels. Unfortunately, handling and mobility have been reduced, but this build is rather effective for taking down armored opponents from medium-range and beyond.

• JAK Harbinger Kit (Aftermarket Part)
• Beast Fifty Long Barrel (Barrel)
• Kimura RYN-03 Vertical Grip (Underbarrel)
• Corio Eagleseye 2.5x (Optic)
• Sakin ZX Grip (Rear Grip)

Best Perk Package

• Focus - Players will experience reduced flinch whilst in ADS, perfect for maintaining accuracy when under fire from opponents.
• Double Time - Extends the time of Tac Sprint, along with reducing its refresh time. Provides players with the means to maintain high mobility, great for getting in and out of high-intensity gunfights.
• Tempered - Players can now replate to full armor with just two plates. Essentially, it reduces armor plate consumption, along with allowing players to get back into the fight much sooner.
• Birdeye - Reveals Ghosted players whilst UAVs are active, along with enhancing radar effects. Perfect for locating players during the final few circles.

Recommended Secondary

The JAK Harbinger Kit for the M4 converts the weapon into a 50-Caliber Rifle, boosting damage and shredding opponent's armor plates in Warzone Battle Royale. However, the weapon is held back by its low magazine size and ammo reserve. Due to this flaw, players will greatly benefit from equipping a Submachine Gun to switch to during high-intensity gunfights. Some top considerations for the category include the Striker-9, the RAM-7, and the WSP-Swarm.
