The M4 is an Assault Rifle in Call of Duty: Modern Warfare 2. The iconic weapon has been part of the franchise ever since the advent of Call of Duty 4 and is a staple for the Modern Warfare series. Since its first appearance, the weapon has been included in Black Ops 2, Ghosts, Modern Warfare (2019), Modern Warfare 2 (2009 and 2022), and countless other installments, albeit with different names.

Best M4 loadout in Modern Warfare 2

When building the best M4 loadout in Modern Warfare 2, you must carefully pick attachments for it. These attachments should help bring the best out of the weapon and simultaneously mitigate its weaknesses. Moreover, you will need to equip the correct secondary set of Perks and Equipment to get the most out of this iconic rifle.

Keeping in mind the pros and cons of Assault Rifles, the following items are recommended:

Attachments

  • Laser: FSS OLE-V Laser
  • Barrel: Hightower 20" Barrel
  • Underbarrel: FTAC Ripper 56
  • Magazine: 45-Round Mag
  • Optic: Cronen Mini Pro

The FSS OLE-V Laser will give you a slight handling boost, allowing you to aim down sight quicker and improving the sprint-to-fire speed. The Hightower 20" Barrel increases the damage range and helps with recoil control.

The FTAC Ripper 56 helps a lot with the recoil and aids in improving accuracy. Meanwhile, 45 Round Mag gives you 15 extra bullets over the base magazine, allowing you to kill more and reload less.

And finally, the Cronen Mini Pro is a clean optical sight that will provide you with a clean and precise vision of the targets.

Now that your weapon is ready for gunfights, we suggest equipping the following:

Perk Package

  • Base Perk 1: Double Time
  • Base Perk 2: Bomb Squad
  • Bonus Perk: Fast Hands/Cold Blooded
  • Ultimate Perk: Ghost/Quick Fix

Equipment

  • Lethal: Semtex
  • Tactical: Stim/Stun Grenade

Field Upgrade

  • Dead Silence
  • Trophy System

You can go with either the X13 Auto pistol or the FTAC Siege for the secondary weapon. Both are exceptionally strong sidearms in the game and can be wielded as an SMG.
