The best Modern Warfare 2 M4 loadout remains a reliable option as the focus starts turning towards the launch of Season 6.

Thanks to the gunsmith, there are plenty of attachments to select in order to optimise the M4 to suit any style of play which is great news if you're looking for something other than the best guns to use.

Before we take a closer look at the best Modern Warfare 2 M4 loadout, check out our guides showcasing the best ranked play loadouts and all there is to know about the next double XP event.

What is the best Modern Warfare 2 M4 loadout?

Hightower 20" Barrel
Cronen Mini Red Dot
Demo D50 Buffer Tube
FSS Sharkfin 90
Rear Grip

This particular build continues to make an impact in multiplayer thanks to its incredibly versatility.

The hip-fire accuracy is particularly useful in those hectic close-quarters engagements alongside an improvement in aim-down sight speed.

Best Modern Warfare 2 M4 attachments

After spending some time testing various attachment combinations, we've settled on this particular build. Check out the full attachment list below:

  • Barrel: Tempus Hightower 20"
  • Optic: Cronen Mini Red Dot
  • Stock: Demo D50 Buffer Tube
  • Underbarrel: FSS Sharkfin 90
  • Rear Grip: XTEN Grip

Although this combination of attachments does impact the ability to control the M4's recoil, it does provide improvements in overall damage output, range, and accuracy. The Hightower barrel increases bullet velocity which has a huge impact in mid-range and long-distance duels.

For a boost in mobility, selecting the Demo D50 Buffer Tube attachment gives you a fighting chance against any fast-moving submachine gunners hurtling around the map.

Best Modern Warfare 2 M4 perks and equipment

Perks work a little differently in Modern Warfare 2 multiplayer. After taking some time to test various combinations, we've found a solid selection alongside two pieces of equipment guaranteed to make an impact.


  • Double Time (Base)
  • Bomb Squad (Base)
  • Fast Hands (Bonus)
  • Ghost (Ultimate)

The combination of Double Time and Bomb Squad is extremely valuable over the course of a match. Increased explosive resistance combined with a double dose of Tactical Sprint allows you to navigate the map with ease.

For our Bonus perk, we've gone with Fast Hands for a faster reload speed, weapon swap speed, and equipment usage speed.

Lastly, our Ultimate perk slot is filled by Ghost. Concealing your location from any enemy UAVs when moving allows you to sneak behind enemy lines and shred through any unsuspecting opponent standing in the way.


  • Semtex (Lethal)
  • Stun Grenade (Tactical)
