Call of Duty Modern Warfare 2 has an updated gunsmith system with added weapon customizations – here’s how it works!

Call of Duty games are all about guns and Modern Warfare 2 is no different. In fact, the game will have a new and improved gunsmith system that lets players tune weapons to their liking.

While Activision has confirmed many new Modern Warfare 2 gameplay details, the gunsmith system was left out.

However, YouTuber TheXclusiveAce was invited to the MW2 preview and has shared everything he knows about the new gunsmith system in the game. Here’s how it works!

But first, here’s how to get early access to Modern Warfare 2’s Beta!

MW2 Multiplayer Gunsmith System Explained

In his latest video, TheXclusiveAce has shared what he was shown about Modern Warfare 2’s gunsmith during Activision’s behind-closed-doors presentation.

Of course, this is still subject to change, but it gives fans a good idea of how weapon customization will work in MW2.

The first major change comes with the attachments themselves. Instead of there being 10 attachment slots, there will be 6 slots for attachments and 4 slots for weapon parts. Here’s how they work.


Firstly, the 6 attachment slots are for muzzle, underbarrel, laser, ammunition, optic, and rear grip. However, players will only be able to equip 3 of these at a time.

Weapon Parts

Secondly, the weapon parts are barrel, magazine, receiver, and stock. TheXclusiveAce believes that you’ll be able to equip all 4 of these to your weapon at once.

Therefore, between the attachment and weapon parts slots, you’ll be able to equip 7 attachments to your weapons.

Attachment Tuning in Modern Warfare 2 Gunsmith

The biggest change to the gunsmith system is the ability to tune individual attachments. The example TheXclusiveAce gave was barrel tuning.

In this case, there were two sliders that would let you adjust how the barrel changes your weapon’s performance. For instance, you can increase the weight to help recoil control, but reduce ADS speed or make the barrel shorter to increase aiming stability at the expense of aim walking speed.

This is perfect for players who love tweaking their weapons and will hopefully let everyone adjust their guns exactly to their liking.

Modern Warfare 2 Firing Range

Finally, in the bottom left corner of the gunsmith screen, there is a button that says ‘Go to Firing Range’. This confirms that MW2 will have a firing range for weapons testing, making it easier for you to try out weapon builds.

And that’s everything you need to know about the new gunsmith system in Modern Warfare 2!
