The Modern Warfare 2 weapon tuning system is only available to you once you’ve maxed out the ranking on your current gun. It takes the mastery of a weapon to the next level and lets you fine-tune the firearm to your exacting standards. The evolved Gunsmith system introduced weapon platforms to Modern Warfare 2 for the first time, changing weapon customisation in the multiplayer game and making it easier to unlock attachments for multiple guns.
If you want to dominate in the FPS game, the right weapon loadout is crucial, and whether that’s the best M4 loadout, the best 556 Icarus loadout, or one of the many other loadouts you can pick, you’re still restricted to the specific attachments created for that weapon. Once you unlock weapon tuning, however, that all changes, with the option to adjust, for example, a barrel’s length or a grip’s weight, further changing stats like recoil control or mobility.
How to tune your weapon in Modern Warfare 2
Weapon tuning becomes available on each of your guns when it is fully levelled up. For example, when you get your TAQ-56 to level 20 or your FSS Hurricane to level 15, the ‘Tune’ button will appear for that weapon, meaning you only have to fully max out one weapon to start playing with weapon tuning.
Each attachment on your given weapon can be tuned, accentuating one stat while devaluing another. For instance, a barrel that gives both recoil control and ADS speed could be altered in weapon tuning so it’s heavier, meaning that the recoil control is improved, but the ADS time gets slower. Weapon tuning even goes as far as how close you want your head to be to your optic, giving you a clearer picture of your target but less information about the things around you when aiming down your sights.
Now you know everything you need to know about weapon tuning, decide which gun you want to level up first from our list of the best Modern Warfare 2 guns. Perhaps you prefer playing with one of the best sniper rifles, to which we’re hoping to see the classic Intervention added in a future update.
