The M4 is a weapon that is available to all right from the very start of the game. In fact, it is essentially the very first Assault Rifle that is available for you to take.

Nevertheless, you must hit level 4 in order to be able to access custom loadouts for your weapons. Custom loadouts allow for you to customize all the aspects of the weapon.

The M4 is the very first weapon in the Assault Rifle class of Modern Warfare 2. It is worthy of noting that levelling it up will help you unlock more Assault Rifles as you progress further into the game, such as the M16.

Best M4 Loadout And Attachments

For the attachments for M4, we have picked the following as the the ones for the best Modern Warfare 2 M4 Loadout:

  • Muzzle: Forge-Tac Castle Comp (Unlocks at 556 Icarus Level 10)
  • Barrel: Hightower 20″ Barrel (Unlocks at M4 Level 15)
  • Stock: Corio Precio Factory (Unlocks at M4 Level 7)
  • Rear Grip: Phantom Grip (Unlocks at FSS Hurricane Level 12)
  • Optic: Cronen Mini Red Dot (Unlocks at FSS Hurricane Level 2)

It is also important to note here that owning the Vault Edition of Call of Duty Modern Warfare 2 will get you immediate access to the full suite of all M4 Platform attachments right from the get-go. This includes all the attachments that have been mentioned above without the need of levelling up any of the weapons mentioned.

Making use of the attachments mentioned above will help you be prepared for almost every situation that you can imagine. Whether it is close combat or an exchange of fire from afar, the M4 will prove to be very handy with these attachments.

Advantages Of The Attachments

  • The Cronen Mini Red Dot is an extremely good attachment if you want to increase the precision of your weapon. The red dot sight greatly enhances your aim as well.
  • A good alternative to the Cronen Mini Red Dot will be the Force Tac Delta 4 if you prefer long-range encounters over close combat. The Force Tac Delta 4 boasts the ability to zoom four times, which is exactly what is needed for long-range encounters.
  • The Corio Precio Factory is an exceptionally good attachment for limiting the recoil of the weapon, allowing you to gain better control over the aim. This is especially useful for long-term encounters where recoil puts the target out of your aim after very few shots.
  • The Phantom Grip provides you with a boost to your speed when you are aiming down the sight as well as the Sprint to Fire speed. However, if you wish to control recoil further, the Forge-Tac Castle Comp will help keep your aim steady.
  • For the Barrel, the Tempus Hightower 20″ Barrel functions as a huge improvement to the M4. It allows for the weapon to shoot at a much faster rate. On top of that, it also enhances the weapon’s hip-fire accuracy. Further, it adds to the range of damage of the weapon.

More Attachments

If you want to play around with other attachments and make your own custom attachments build, you will have to unlock them. This can be done by leveling up different weapons in Call of Duty Modern Warfare 2. For instance, once you unlock the 0.50 GS handgun, you have to level it up until you reach level 4 to unlock the Corio RE-X Pro sight.

Make sure to play with as many weapons as you can as you unlock more weapons and attachments along the way.

Weapon Tuning

Call of Duty Modern Warfare 2 also comes with a feature known as Weapon Tuning which can be unlocked by maxed out levelling any weapon. Weapon Tuning allows for you to tweak the weapon’s stats further with even greater customizability. This is also done by tweaking the attachments and will allow for you to design the weapon to match your preference completely.

Best M4 Class Build (Perks And Equipments)

For the perks and equipments for M4, we have picked the following as the the ones for the best Modern Warfare 2 M4 Loadout:

  • Basic Perk 1: Overkill or Bomb Squad
  • Basic Perk 2: Scavenger or Double Time
  • Bonus Perk: Fast Hands
  • Ultimate Perk: Quick Fix or Ghost
  • Secondary Weapon: Expedite 12
  • Tactical Equipment: Stun Grenade
  • Lethal Equipment: Proximity Mine or Semtex
  • Field Upgrade: Munitions Box or Dead Silence

Basic Perks

Overkill and Scavenger are aimed at making quick combat easier for you. Overkill allows you to have two primary weapons at the same time. In Modern Warfare 2, you need to have Scavenger in order to pick up ammo from dead bodies lying around.

Alternatives to these are Bomb Squad and Double Time. Bomb Squad helps protect you from different forms of explosives, while Double Time helps you sprint even faster which is definitely a much required feat.

Bonus Perk

Fast Hands is the entry for our recommended Bonus Perk in Modern Warfare 2. As the name indicates, Fast Hands primarily allows for you to reload faster. In addition to that, it also allows for you to switch to your secondary gun as well as to use equipment faster as well. It comes in very handy when you are carrying a secondary weapon, combined with Scavenger.

The M4’s reload speed is a bit tardy in Modern Warfare 2, so having Fast Hands on M4 is absolutely crucial.

Ultimate Perk

For the Ultimate Perk, Ghost is undoubtedly a must-have option considering its up-time. It essentially keeps you invisible from being detected on the enemy’s UAVs, Heartbeat Sensors and Portable Radars. This allows for you to sneak around the map effortlessly with maximum stealth.

A good alternative is Quick Fix. It helps you to survive during combat and also allows health regeneration upon every kill that you make.

Secondary Weapon

For the Secondary Weapon, we have chosen Expedite 12 as the best option. It is a powerful weapon from the Shotgun weapon class, and is an extremely powerful weapon for close combat situations. Fast Hands allow for it to become an even better option to keep.

Tactical Weapon

For the Tactical Weapon, we have chosen the Stun Grenade which has been the go-to secondary grenade for Call of Duty players for generations. It helps you disorientate enemies before entering rooms or corridors, giving you an advantage over them. You could spice things up with taking the Expedite 12 out to confirm kills with this strategy.

Flash Grenade

The Stun Grenade is not available until you hit level 15. The Flash Grenade can serve a very similar purpose in that it does blind the enemy like a Stun Grenade does, but does not slow them down.

Lethal Weapon

The Proximity Mine has also been a very beloved equipment of Call of Duty players for generations. It helps you take advantage of coverings and the element of surprise behind doors and corridors. It can also be used defensively at the entrances of rooms and corridors where you are hidden from the enemy.

An alternative to the Proximity Mine is Semtex. Semtex might not be as handy as a stun grenade, but it does help deal quite some damage to the enemy, which is always required.

You could also go with the Frag Grenade for your Lethal Weapon. Unlike Proximity Mines, Frag Grenades are much more offensive and help you clear out rooms and other dense areas of enemy in one go.

Field Upgrade

For the final entry on the best M4 loadout for Call of Duty Modern Warfare 2, we have the Field Upgrade. We have chosen Munitions Box as the go-to option for your Field Upgrade.

Munitions Box throws a box of ammunition in front of the player which automatically gives one magazine for nearby teammates’ weapons, and can be interacted with to give one of each equipment. The owner also receive points whenever a teammate is resupplied by the Munitions Box. It is available by default.

The Munitions Box can be destroyed, causing it to explode and deal damage in the process.

Portable Radar And Dead Silence

As the Munitions Box is not available until you hit level 16, you can go for the Portable Radar which is unlocked when you hit level 5. Portable Radar emits a periodic ping to detect nearby enemies.

A good alternative to Munitions Box is Dead Silence. Dead Silence serves to temporarily make your footsteps silent, allowing you to maximize stealth. The duration of Dead Silence is refreshed upon killing an enemy with gun, melee or throwing a knife.

Assault Perk Package

It is important to note that you cannot equip many of these custom perks until you reach the required levels. For that, we recommend that you go with the Assault Perk Package which is available right from the get-go. It comes with all the listed perks excluding Fast Hands, in place of which you will get Hardline. Hardline is a good alternative which will allow you to hit killstreaks with lesser kills or score.


Call of Duty Modern Warfare 2 is here, and it is no wonder that out of all the guns that the game features, the classic M4 is a favorite one of many players. Assault Rifles have generally been one of the most, if not the most popular, weapon classes in Call of Duty games, and Modern Warfare 2 is no exception.v
