How do you unlock MW3 aftermarket parts? A new feature for Modern Warfare 3 aftermarket parts are modifications to your weapons that fundamentally change how they function. The primary focus of riddling your enemies with holes stays the same, but with aftermarket parts, you can alter how they do it, in quite a dramatic fashion.
Modern Warfare 3 season 2 is here, and the previous season brought us several stand-out weapons and aftermarket parts to make your best MW3 loadouts even better. The new season keeps up with four new weapons and a bunch of thrilling aftermarkets parts we can’t wait to rev up. Here are all the Modern Warfare 3 aftermarket parts so far and how to unlock them.
Season 2 new aftermarket parts
Season 2 comes with some zombie-killing attachments, including perhaps the coolest aftermarket part to date – the JAK Limb Ripper Chainsaw. Yep. We’ve have Ash as an operator, and his chainsaw and boomstick as blueprints, but now we can add our own chainsaw aftermarket part to our favorite weapons.

A barrel attachment that significantly decreases recoil, while increasing your impact on the minimap while firing.

All Modern Warfare 3 aftermarket parts
Aftermarket parts in Modern Warfare 3 are an additional layer of customization, they are complete conversation kits you can unlock for certain weapons that affect how the weapon performs, looks, and how you can further customize it.
These aftermarket parts are unlocked by ranking the gun to its maximum level. Once the gun has been maxed out, you can transform your weapon into something remarkably different.
Here is every aftermarket conversation in MW3:
Rennetti Handgun with Full-Auto Carbine
The Full-Auto Carbine aftermarket conversion for the Renetti transforms the handgun from a burst first secondary into a fully-equipped SMG. With a 3D printed frame surrounding the base body, the Full-Auto Carbine gives you additional customization options, such as a stock, and an underbarrel attachment.
Pulemyot LMG Jak Annihilator
The bullpup aftermarket conversion kit for the Pulemyot LMG transforms the weapon from a bulky, low-mobility weapon into a much more agile assault rifle. Shortening the barrel and lightening the main body of the LMG allows for a much higher movement speed, ADS speed, and primes the Pulemyot for the smaller MW3 maps like Rust.
MCW Jak Raven Kit
The Jak Raven Kit for the MCW replaces the gun’s body so it can fire .300 rounds, adding damage to an already formidable weapon. You lost recoil control, and some range, but this aftermarket conversation more than makes up for that with its close-range shredding capability.
MTZ 762 Jak Heretic Carbine Kit
This conversation for the MTZ 762 increases the rate of fire of the rifle, and the mobility of your operator, at the expense of damage and bullet velocity. One for mid to close-range encounters, this aftermarket part creates a mobile, CQB monster.
WSP 9 Broodmother 45 Kit
The Broodmother 45 kit is an interesting conversion that completely changes the WSP 9, taking it from a fast-firing SMG to a hard-hitting, almost assault rifle-like gun. Fire rate is slowed down but damage has been vastly increased while still maintaining the innate mobility you get from using an SMG.
DG 58 LSW Jak Nightshade Rifle Kit
The Jak Nightshade Rifle Kit completely transforms the DG 58 LSW, increasing the rate of fire to almost ludicrous proportions. The recoil control takes a huge hit as a result, but if you can land your shots, you’ll win any gunfight that comes your way.
MCW 6.8 Full-Auto Conversion
This full auto conversion takes what is already a devastating weapon and turns it up to 11. The recoil control can be a problem, but the fire rate isn’t too heavy, making it manageable. Land a few shots in quick succession with the MCW 6.8 and your enemies will rue the day they crossed your path.
Cor 45 XRK IP V2 Conversion Kit
While it may look like a ray gun from the future, this conversion kit for the Cor 45 is very real and absolutely devastating. The XRK kit adds an interesting firing mechanic whereby a round is fired when you press the trigger, and then another is loosed when you let go, meaning that you can unleash a barrage with a few clicks that nobody is coming back from.
Those are all of the MW3 aftermarket parts so far, with more to come in future seasons.
