Aftermarket Parts offer substantial enhancements to your weaponry, making it crucial to understand and utilize the Aftermarket System effectively to elevate your CoD gameplay. Here's a comprehensive guide detailing the step-by-step process to unlock all Modern Warfare 3 Aftermarket Parts.

How to Unlock Modern Warfare 3 Aftermarket Parts

Players have two choices when looking for MW3 Aftermarket parts: Weekly Challenges or Armory Challenges. Normally, these parts get introduced in Weekly Challenges, where you must complete specific tasks to get them. Once the specific Weekly Challenge wraps up at the season's end, these Aftermarket Parts become accessible through Armory Challenges so that they remain accessible without any expiration date. No need to worry, therefore, if you miss the Weekly Challenges.

Before players can use an Aftermarket Part, however, their associated rifle must reach the maximum weapon level. For this reason, players should prioritize leveling up their weapons first.

What are Modern Warfare 3 Aftermarket Parts?

The aftermarket system in Modern Warfare 3 offers an extra layer of customization by offering complete conversion kits designed for specific weapons. These parts substantially affect both the performance and visual aspects of firearms, providing a greater degree of customization. This feature expands players' control over their weapons and seamlessly works alongside the MW3 Gunsmith and MW3 camos functionalities. Here are all the aftermarket parts featured in the game:

Here is a more detailed breakdown of these combinations:

JAK Heretic Carbine Kit – MTZ-762

The JAK Heretic Carbine Kit is purpose-built for enhancing the MTZ-762 battle rifle, appealing to players who adopt a more forceful and aggressive style of play. This modification boosts the MTZ-762's firing rate and the operator's mobility but reduces both damage output and bullet velocity.

The Jak Raven Kit equips the MCW to fire .300 rounds by replacing the gun's body, further augmenting this formidable weapon's already impressive damage capabilities. This comes at the cost of damage, bullet velocity, and range, however.

Tailored as a high-damage conversion kit, the Broodmother .45 Kit is specifically crafted for the WSP-9 SMG, enhancing the effectiveness of this potent weapon, particularly advantageous in close-range battles. Although it reduces the firing speed, it significantly boosts damage while preserving the inherent mobility associated with using an SMG.

The Pulemyot LMG transforms from a ponderous, less mobile weapon to a notably agile assault rifle when you pair it up with the bullpup aftermarket conversion kit. The massive magazine still hinders mobility to some degree, so don’t expect SMG-like flexibility.

This setup might look like something out of a sci-fi flick, but this is no movie prop in Modern Warfare 3! You can inflict some serious damage on your opposition with the Cor 45 and XRK IP V2 Conversion Kit combo. Not the best pick for taking out long-range targets, but you will love this more than a handgun in short-range combats.

The JAK Ferocity Carbine Kit is an MW3 Aftermarket Part that works its magic on the Renetti handgun by incorporating 3D-printed parts, transforming it into a carbine. You can expect boosts in bullet velocity, range, and firing speed, though there's a minor dip in mobility and recoil control.

WSP Akimbo Brace Stocks – WSP Swarm

Say hello to the WSP Akimbo Brace Stocks Aftermarket Part, revamping the lethal WSP Swarm SMG into a dual-wield beast, perfect for close-quarters annihilation. Reinforcing the weapon's frame, this nimble SMG now enables an aggressive dual-hold stance, giving up some range and mobility in exchange for overwhelming firepower.

MCW 6.8 Full-Auto Conversion Kit – MCW 6.8

This full-auto conversion kit kicks an already devastating weapon into overdrive. Embracing the full might of the marksman rifle category, this Aftermarket Part seamlessly morphs the weapon into a formidable, high-powered assault rifle.

Intlas CAS-14 – optic

This 2.5x optic is tailor-made for mid-range battles and includes an awesome built-in laser. It's the perfect companion for your beloved assault rifle, battle rifle, marksman rifle, or sniper rifle.

Cronen Intlas MSP-12 – optic

This is a red dot optic spiced up with an integrated laser for that bullseye accuracy boost! It is a great choice for SMGs, assault rifles, and all your close-range setups. With loads of red dot sights out there, however, I wouldn’t say that this one is an immediate must-own accessory.
