Weapon Tuning is one of the new systems available in Modern Warfare 2 that allows you to tune different attachments to make them more functional in regard to your own gameplay. For example, you can fine-tune the different attachments of an M4 to provide more stability, recoil control, or better ADS speed and further.

Taking the barrel of an M4, if you tune this attachment in MW2, you can toggle between Recoil Control and ADS Walking Speed on the Left Slider. The bottom slider allows you to toggle between ADS Speed and Damage Range. Simply put, weapon tuning in Modern Warfare 2 will allow you to adjust your weapon even further.

How to Unlock Weapon Tuning in Modern Warfare 2

Here’s where most players will have a hard time as you will have to grind a lot to be able to use weapon tuning. Since this is a highly advanced feature that will help you stabilize your setup even further, the devs have kept it as the last part of your weapon grind.

That is, you will have to max out your weapon before you can use the tuning system in MW2. So if you are an M4 user, you will have to level up 20/20 and that can be difficult if you don’t know how to level up guns fast.

How to Tune Weapon & Attachment in MW2

Since the difficult part about this system is unlocking it, the devs have kept it very simple on how to do it. Here’s how to tune your weapon & attachment in MW2:

  • Head over to your Multiplayer loadout from your Weapons and then select the weapon you want to use the tuning system for in MW2.
  • Once you select the weapon, click on Gunsmith and then head to the attachment you want to tune.
  • When you click on Tune, you will be able to use your Left Analog to toggle between the tuning options. Keep an eye on the graph at the center as it will show you the results of all your tweaks.

Which Weapon Attributes can you Tune in Modern Warfare 2?

Now that you know about the weapon tuning system of MW2, you need to have a look at all attributes that you can toggle between. Here are the attributes you can tune in Modern Warfare 2:

  • Handling
  • Damage
  • Fire Rate
  • Mobility
  • Range
  • Recoil Control
  • Accuracy
  • ADS Speed
  • Aim Walking Speed

All of these will help you create a formidable weapon that you can use in Modern Warfare 2. Additionally, Optics have a few more attributes that are related to them.
