Best Modern Warfare 2 M4 loadout

You won’t find a more well-rounded assault rifle than the best M4 loadout, so give this gun a try to dominate opponents in Modern Warfare 2

Call of Duty Modern Warfare best M4 loadout: the stock M4 in MW2's Gunsmith menu

The Modern Warfare 2 best M4 loadout is one of the best guns you can get your hands on, especially in the early stages of the game. The stock version of the M4 is an incredibly well-rounded weapon, but it can be transformed into the best AR of the bunch if you utilise the correct set of attachments.

Another reason to equip the M4 is to unlock a range of attachments for the other guns in your arsenal. Thanks to the changes made to the Modern Warfare 2 Gunsmith, if you primarily use the M4 in combat, you automatically unlock attachments for any gun within the M4’s weapon platform, which helps in kitting out the best Modern Warfare 2 assault rifle. Here’s what you need to create the best M4 loadout in Modern Warfare 2.

Best M4 loadout attachments

The best Modern Warfare 2 M4 loadout is:

  • Muzzle: Forge-TAC Castle Comp
  • Barrel: Hightower 20″ Barrel
  • Optic: Cronen Mini Red Dot
  • Rear Grip: Xten Grip
  • Underbarrel: VX Pineapple

The Forge-TAC Castle Comp is perfect for the M4 as it improves both the horizontal and vertical recoil control without sacrificing its damage output. This muzzle does hurt your aim down sight speed and aiming stability, but these downsides are negligible at best. Furthermore, the base M4 has a surprisingly high aim down sight speed, so we can afford to take a few hits in this area.

We can improve two vital areas by equipping the Hightower 20″ Barrel which enhances the M4’s bullet velocity and damage range. With this attachment, the assault rifle can take down enemies faster than before, and from further away. This also comes with a minor buff to the weapon’s hip fire accuracy and recoil control. As for the negative effects, you may feel slower using this barrel as it hurts the assault rifle’s movement speed and aim down sight speed.

As for the optic, this is completely down to personal preference. We found that the Cronen Mini Red Dot produces a clean view, making it easy to take down any targets at close to medium range. If you don’t have any problems using the M4’s iron sights, it may be worth adding a stock attachment instead. Equip the Xten Grip to improve the M4’s mobility, specifically the sprint-to-fire speed and ADS speed. This should help negate some of the Hightower barrel’s downsides.

Finally, the VX Pineapple underbarrel hurts the M4’s mobility stats for better accuracy and recoil control overall. Not only does this underbarrel improve the gun kick and hip recoil control, but it also includes a boost to the gun’s hip fire accuracy in case you find yourself in an awkward close-range situation.

And there you have it, the best M4 build in Modern Warfare 2. Pair this assault rifle with the best MP5 loadout to dominate from every distance. The M4 is undoubtedly one of the best Modern Warfare 2 guns, but if you’d like to experiment with a different weapon class while still bringing the heat, then our compilation of the best Modern Warfare 2 loadouts will steer you to victory.
