Modern Warfare 2 Best M4 loadout

The best M4 loadout in Modern Warfare 2 focuses on increasing control, stability, and range, while maintaining some of its snappy speed. The M4 has an impressive time to kill in a game that already boasts a very low time to kill. That means you simply need to increase the control so that you can hit more consistently, and maintain your movement speed so that you can still charge around the map at breakneck pace.

Here is the best MW2 M4 loadout:

  • Muzzle: Echoline GS-X
  • Barrel: Hightower 20” Barrel
  • Rear Grip: Sakin ZX Grip
  • Stock: Corio Precio Factory
  • Laser: Schlager PEQ Box IV

Modern Warfare 2 best M4 attachments

The best M4 attachment in MW2 is currently the Tempus Hightower 20" Barrel. It boosts recoil control, bullet velocity, and damage range. That makes the M4 far better at medium range, allowing you to easily snap to and rinse enemies with precision. Thanks to the fast TTK in Modern Warfare 2, the increased damage range and bullet velocity will ensure that enemies die almost immediately to your shots. It does bring down ADS speed, but you can counter that using the Schlager PEQ Box IV laser.

To push recoil control even further, equip the Sakin ZX Grip, Corio Precio Factory stock, and the Echoline GS-X suppressor. It might sound simple, but combining these attachments will make the vertical and horizontal recoil much easier to handle, and it won't feel much slower than usual. Sure, you could focus on speed to dash around faster, but for Modern Warfare 2's fast TTK, we'd argue it's better to land those shots when it matters.

Modern Warfare 2 best M4 secondary weapon

While the M4 should be able to clear most enemies with ease, we recommend using the Lachmann Sub in your secondary slot. This is an excellent short-range SMG that's the ideal partner for the M4, offering speed and power while dashing around the map. You can switch between them as the situation demands, using the M4 for longshots and holding angles, and the Lachmann Sub for speed and quick pushes.

Modern Warfare 2 best M4 perks

The best MW2 M4 perk is Overkill. This allows you to use two primaries, so you can equip the Lachmann Sub as your secondary. For your second basic perk, take Double Time to double the duration of your tactical sprint so that you can charge around the map at full speed more often while hunting for enemies. If your tactical sprint does run out, the Battle Rage Field Upgrade will quickly refresh it and get you back to full speed in no time.

For your bonus perk, we recommend using Fast Hands, which will allow you to swap between the M4 and your secondary weapon faster. For your ultimate perk, take Quick Fix to get some bonus health regeneration whenever you kill an enemy. It's one of the best MW2 perks and will keep you alive for longer.

If you find yourself fighting a whole group of enemies and your M4 isn't cutting it, we suggest tossing in a Thermite grenade to thin the crowd. If you take some hits in the fight, use the Stim Shot to regenerate health quickly and reset your tactical sprint cooldown.

That wraps up our best M4 loadout in Modern Warfare 2. Now that you're ready to get out there and win some games, make sure you are using the best killstreaks in Modern Warfare 2.
