The M4 is widely considered the best Assault Rifle to use in Modern Warfare 2 simply because of its versatility. This weapon has 20 unlockable levels, and you need to level up quickly to unlock its Weapon Tuning. The M4 has impeccable Recoil Control, Accuracy, and Fire Rate. Although it lacks in the Mobility and Handling department, players can mix and match attachments to improve these aspects.

The M16 is the best burst-fire Assault Rifle in Modern Warfare 2. It shoots three-round bursts, and you can alternate between single and burst fire. If you have a seasoned trigger finger, we recommend firing single rounds instead of burst, as the M16's Accuracy is beyond compare. However, you can add a Barrel attachment, it's best not to do so as it affects the M16's Range and Accuracy.

The Kastov 74-u is a mix between an SMG and an Assault Rifle. You can unlock this weapon by leveling up the Kastov 545 to level 13. Although Kastov 74-u lacks Recoil Control and Accuracy, its Mobility and Handling make up for these aspects. You can effectively create a run-and-gun build with this weapon as it has the best of both SMG and AR classes.

The TAQ-56 AR is another powerful Assault Rifle using the Tactique Verte Platform. You can unlock this weapon by reaching level 19 in the game. The TAQ-56 has 20 progression levels, and you need to level up quickly to unlock all the attachments. The TAQ-56 lacks in Range, but you can fix that by equipping the 14.5" Tundra Pro Barrel.
