Discover all MW3 Conversion Kits and Aftermarket Parts! Learn how to unlock them, their effects, and how they transform your weapons in Call of Duty: Modern Warfare III.
Alright, let's break down the new Conversion Kits and Aftermarket Parts in Modern Warfare III. These are seriously cool additions that can totally change how a weapon feels and performs. Think of them like a whole new way to build your favorite guns. We've got a rundown of what's available right now, how to get your hands on them, and what they actually do to your weapons.
Right now, the devs have dropped a few of these kits, but they're planning to roll out more as the game goes on and through seasonal updates. If you missed out on a weapon's specific challenge when it first came out, don't sweat it – these kits will eventually become standard attachments you can earn later. This means you won't miss out on any of the unique playstyles these kits offer.
| 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. | . |
| WSP-9 (SMG) | Broodmother .45 Kit. | Turns the weapon into an SMG / AR hybrid using .45 rounds. Think 74u type weapon. | . |
| COR 45 (Pistol) | XRK IP-V2 Conversion Barrel | Enabled optic and under-barrel attachments alongside doubling the fire rate. | . |
On top of these kits, you've also got Aftermarket Parts. These are special attachments designed to work with the conversion kits, really leaning into those new playstyles. For example, the Renetti Conversion Kit can get the WSP Akimbo Aftermarket option, turning your full-auto pistols into something like an Akimbo MP7. You'll unlock these through challenges too, which we'll know more about when they drop.
