8 brand-new Aftermarket Parts are coming to Modern Warfare III and Warzone in Season 4 from May 29. These include improvements to older weapons like the Lachmann Shroud and the Kastov 762.

Aftermarket Parts are a way to alter weapons in Call of Duty MW3 or Warzone after they have been leveled up. They might turn a shotgun into a long range Marksman Rifle or add a flamethrower to Assault Rifle.

Warzone Season 4 will introduce 8 new Aftermarket Parts for players to unlock via the Weekly Challenges set out in Modern Warfare III, Modern Warfare Zombies, or Warzone.

JAK Harbinger Kit

  • Compatibility: M4 Assault Rifle (MWII)

This .50 Cal conversion kit for the M4 is an extremely deadly, quick-kill weapon. The slow fire rate, drop in bullet velocity, and a significant increase in recoil will require a careful hand.

JAK Gunslinger

  • Compatibility: Basilisk Handgun (MWII)

A frame and cylinder conversion that allows the revolver to hold eight rounds of .357 ammunition with an exceptional increase to rate of fire and a near instantaneous trigger action.

JAK Volkh

  • Compatibility: KV Inhibitor Sniper Rifle (MWIII)

A meticulously crafted stock and receiver modification that updates the weapon to fire a two-round burst at minimal MOA dispersion, making every trigger pull count.

JAK Scimitar Kit

  • Compatibility: FJX Horus Submachine Gun (MWIII)

Improved range and recoil are standard with this aftermarket kit which also unlocks the use of a high-capacity drum mag for the FJX Horus.

JAK Thumper-656

  • Compatibility: RGL-80 Launcher (MWIII)

An improved long barrel for an infantry-carried grenade launcher. Fires projectiles at higher velocities and distances. Compatible with a wider variety of launcher projectiles.

JAK Requiem

  • Compatibility: Kastov 762 Assault Rifle (MWII)

A counter-balanced rifle system designed to completely eliminate vertical recoil.

JAK Decimator

  • Compatibility: Lachmann Shroud Submachine Gun (MWII)

This modification allows the Lachmann Shroud to fire in full auto.

JAK Intimidator

  • Compatibility: Renetti Handgun (MWIII)

Slow down your fire rate and take more deliberate shots with this modification that changes the Renetti to a single-shot weapon.

The exact order that these Aftermarket Parts will release in is currently unknown. More soon.

All Season 4 Aftermarket Parts are also unlockable throughout the season by spending Arsenal Coins in the Arsenal Store in Call of Duty: Warzone Mobile. Once purchased in WZM they can be used across WZM, MW3, and Warzone.
