Call of Duty: Modern Warfare 2 offers weapon customization for some of your favorite guns. It’s a good way to customize guns to your liking and provides more control over how you want your weapons to handle. If you’re trying to figure out how to access weapon configuration, I’ll explain what you need to know.
Weapon customization is not initially available and you will need to unlock it before you can start using the feature. To add to the confusion, Infinity Ward has disabled weapon configuration temporarily (opens in a new tab) due to crashing issues but you can follow the steps below after it has been re-enabled. Here’s how to unlock a Modern Warfare 2 weapon configuration.
Modern Warfare 2 weapon customization: How to unlock
To unlock the customization option in Modern Warfare 2, you’ll need to get your weapon to its maximum level and luckily, getting XP for weapons is as easy as using them during a match. Before you start grinding those levels, though, make sure your gun of choice can be edited in Gunsmith—this is a pretty solid indicator that you’ll be able to customize the weapon once you max it out.
Once you’ve unlocked a weapon configuration, you can add attachments to your gun, which can then be customized to your liking. Visit the Gunner from your loading screen, then look for the “Tune” button above a fitted add-on. You will have two sliders that will change the variables. In the example above, you can make adjustments to range, accuracy and handling, although improving one will reduce the effectiveness of another, so you should play around and see what works for you.
