Modern Warfare 2 attachment tuning: What is attachment tuning?

Learn more about the new attachment tuning feature in Modern Warfare 2

Want to learn more about attachment tuning in Modern Warfare 2? Attachment tuning is a new feature in Call Of Duty: Modern Warfare 2 that allows you to tweak attachment stats after reaching max level with a weapon. The tuning menu has sliders with key stats at either end. Moving the slider cursor towards one end will improve that stat, while harming the attribute at the opposite end.

In this guide, we’ll break down everything you need to know about attachment tuning in Modern Warfare 2, including info on what attachment tuning does, whether attachment tuning is worth using, and whether it is currently active in Modern Warfare 2 multiplayer.

Is attachment tuning back in Modern Warfare 2?

As of Friday, November 4 2022, Modern Warfare 2 attachment tuning is back.

Infinity Ward confirmed in a tweet that "the attachment tuning feature has just been reenabled", and promised more details over on the official Call Of Duty blog.

This is a follow-up to the events over launch weekend, when Infinity Ward tweeted that they were “disabling attachment tuning until further notice”. The tweet went on to state they were investigating crashes that would occur when a player had five tuned attachments on the same weapon.


What is attachment tuning in Modern Warfare 2?

Attachment tuning is a new system that allows you to tweak stats for various attachments upon reaching max level with a gun. Take a look at our Modern Warfare 2 progression guide if you want to reach max level quickly.

To use attachment tuning, you must reach max level (level 20) with a specific gun, and then head to the gunsmith menu. From there, equip an attachment and you should see a small box pop up directly above it that says "tune". Pressing on that button will bring up the menu shown in the picture below.

It's worth noting that you can't tune every attachment. From what we've seen so far, you can't tune magazines or lasers, as well as attachments that essentially remove part of the gun (such as the LM Stockless Mod in our MP5 loadout).

Everything else should have the tuning ability, but attachments of the same type might not impact the same stats. You'll need to play around and investigate individual attachments to see which stats they can improve through tuning.

From some early testing, attachment tuning seems to have negative effects that are far more noticeable than the positives. Improving a stat through attachment tuning will often offer a very small 5-10% bonus to its score, if any, while negatively impacting the attribute at the other end of the slider by up to 20%.

Looking at the image above should hopefully put that into context, as improving ADS speed with attachment tuning involves moving the cursor away from, and therefore harming, your recoil stabilisation.

The gains you will get from focusing on ADS speed will probably be unnoticeable. The negatives for recoil stabilisation will have much greater impact, though, meaning that you might end up weakening your gun overall.

That means attachment tuning often isn’t worth the time or effort, as it won’t drastically improve a gun in most cases. Even if you do see positive changes to certain stats, the negatives could make the gun feel far worse to use. Attachment tuning is risky, and won't prove necessary to win in casual games.

The one exception is optics tuning, which has a unique tuning slider from which you might benefit a lot: Eye Position. Eye Position tuning allows you to change the position of the optic when you aim down sights. Moving it further away will give you more space at the sides to see around the gun, while a close Eye Position might make it easier to focus on enemies through your scope.

That’s everything you need to know about attachment tuning right now in Modern Warfare 2. If you’re looking for some top guns to use in the current meta, take a look at our Modern Warfare 2 M4 loadout, FFS Hurricane loadout, and FTAC Recon loadout.
