Call of Duty: Modern Warfare 3introduces a couple of new ways to trick out your weapons with better attachments and wilder play styles. The conversion kits and aftermarket parts inMW3are worth checking out.
How to unlock all Conversion Kits inMW3
Conversion kits are items you can equip on certain weapons in the game to change them entirely. They might make a pistol turn into a submachine gun or an assault rifle become an SMG and so on. The catch with these is they often only work for one or two weapons, which makes them quite limited.
Fortunately, it is quite easy to unlock the conversion kits inMW3. When a new one releases in the game, it usually comes with a limited time season challenge. These may only last for a week or an entire season, but if they expire, they then turn into Armory Unlocks. This is where you add them to your queue and then complete 2-5 daily challenges to unlock the conversion kit for your weapons.

Here are all of the conversion kits inMW3:
How to unlock all Aftermarket Parts inMW3
Aftermarket parts work similarly to the conversion kits but usually offer solely attachments. These attachments often feel more overpowered compared to the usual options. Like the conversion kits, some of these come with their own limited-time challenges but if you wait long enough, they will appear in the Armory Unlock system. Complete 2-5 daily challenges and they are yours.
