Call of Duty: Modern Warfare 3, like many of the franchise’s installments before it, has loads of weapons and attachments. It can get a bit confusing keeping track of what everything does. A newer item for some weapons is the Conversion Kit. A few new ones were introduced with the recent season two update. What are Conversion Kits and should you be using them?
What is a Conversion Kit in MW3?
Conversion Kits inCall of Dutyare exactly what they sound like. They convert a weapon into something else. We’re not using hyperbole here, as they literally transform a pistol into an SMG, for example. One caveat is that the weapon you’re applying the Conversion Kit to has to be max level. So don’t expect to pull out a brand new, unleveled weapon and change it to something else. Using one of these kits requires unlocking it and leveling up the weapon it’s used on as high as possible.
Conversion Kits can change the way a gun fires, add unique optics you can’t get elsewhere, or even add a fancy underbarrel weapon. With theseason two update, players can now unlock the JAK Limb Ripper under-barrel conversion kit, which puts a chainsaw on your gun.
