Modern Warfare 2 multiplayer contains an extensive gunsmith featuring a huge variety of attachments. With so many to choose from, it can prove tricky to find the strongest combination. After some testing, here's what we recommend:

Although this set of attachments slightly increases recoil, it's still easy to control when firing the Kastov 545 for a continuous period of time. The Prolite TL3 stock is the star of the show, increasing sprint speed and improving ADS speed to guarantee fast reactions.

Additionally, the Ivanov ST-70 grip provides some much-needed flinch resistance which makes all the difference when trying to maintain focus when the bullets are hitting you during a gunfight.
