Call of Duty: Modern Warfare III

All MW3 Conversion Kits & Aftermarket Parts (So Far)

Craig Robinson

With every Call of Duty, there is always some new form of feature, and for MW3, there are a few. Yet, one of the most refreshing ones is the new multiplayer loadout change feature called Conversion kits. Essentially, players unlock new parts that allow you to convert a weapon into an entirely different form. Typically, it offers you a complete change in the gun’s profile, allowing you to get an entirely fresh take on the weapon. Here’s a closer look at the conversion kits in MW3, and what you can expect.

All MW3 Conversion Kits at Launch

As it currently stands, the CoD developers have only released a few of the conversion kits to the game. We will gradually update this list with more information on what to expect from the feature as the multiplayer goes live and we see what guns have them. The current plan is for 6 of the Aftermarket Conversion Kits at launch, with more coming through Pre-Season and seasonal content updates. In addition, if you missed the seasonal challenge with the weapon, then you can expect them to become attachments to the gun later on in future seasons. This allows players to go back and get any challenges they may have missed if they want to play with those kits. For more information, feel free to check out the CoD Blog for more info on MW3 weapons.

Gun Conversion kit Effect Challenge
Pulemyot 762 (LMG) Jak Annhiliator Bullpup Kit Trades range and damage for mobility. Get 25 kills while hip-firing or using Tac-Stance.
Renetti (Pistol) Jak Ferocity Carbine Kit Transforms into an Automatic SMG-type weapon. Get 30 kills with five attachments equipped.
MCW (AR) JAK Raven Kit .300 round conversion to grant better damage profile. Post-launch challenge to be revealed.
MTZ-762 (BR Rifle) JAK Heretic Carbine Kit Adds better control for the high powered 762 rounds. Post-launch challenge to be revealed.
WSP-9 (SMG) Broodmother .45 Kit. Turns the weapon into an SMG / AR hybrid using .45 rounds. Think 74u type weapon. Post-launch challenge to be revealed.
COR 45 (Pistol) XRK IP-V2 Conversion Barrel Enabled optic and under-barrel attachments alongside doubling the fire rate. Post-launch challenge to be revealed.

Also, it’s worth noting that each conversion kit comes with special attachments, known as Aftermarket Parts. These Aftermarket Parts are attachments designed for the conversion kits, offering some special options for those new playstyles. For example, the Renetti Conversion kit can gain the WSP Akimbo Aftermarket option, giving your now full auto pistols turn into an Akimbo MP7-style weapon. These aftermarket parts can be unlocked by challenges too, which we will only be aware of at launch.
