Here is the best M4 loadout to use in MW2. You’ll dominate your Modern Warfare 2 lobbies using our build for this trusty weapon!

A reliable and versatile assault rifle, the M4 is back in Modern Warfare 2 and, as always, is a popular pick for many players.

To save you from worrying about which attachments to put on your M4, we’ve made the best loadout for it.

Best M4 Loadout Build in MW2

The best M4 loadout has these attachments that help reduce the recoil of the weapon and increase its accuracy at all ranges:

  • Muzzle: FTAC Castle Comp (Unlocked at 556 Icarus Level 10)
  • Barrel: Hightower 20″ Barrel (Unlocked at M4 Level 15)
  • Optic: Cronen Mini Red Dot (Unlocked at FSS Hurricane Level 3)
  • Underbarrel: FTAC Ripper 56 (Unlocked at Lachmann-762 Level 6)
  • Rear Grip: Sakin ZX Grip (Unlocked at M4 Level 8)

Here’s the fastest way to level up guns in MW2 so you can access all of these attachments as soon as possible!

Updated Best M4 Loadout MW2

The FTAC Castle Comp Muzzle reduces your horizontal and vertical recoil, making it much easier to keep your shots on target.

The Hightower 20″ Barrel also helps with your recoil control as well as your bullet velocity and damage range. It does slow down your mobility with the M4, but it’s a small price to pay to make it a long-range powerhouse.

We suggest using the Cronen Mini Red Dot as it is one of the clearest sights in the game and can work well at close and long range. However, if you prefer another optic, feel free to go with that!

The FTAC Ripper 56 is the best underbarrel attachment for the M4 as it stabilizes your recoil, once again helping you hit your shots.

To top it off, select the Sakin ZX Grip. This also helps your recoil control, making your M4 pinpoint accurate!

How to Unlock the M4

The M4 is the first weapon every player has access to in MW2.

As soon as you unlock custom loadouts in MW2, you will be able to make your own custom M4 build.

Best Secondary to Use With M4

The Basilisk is our choice as the best secondary weapon to go alongside the M4. This is because it can deal loads of damage and players with accurate aim can use it to finish off enemies with one or two shots.

It might be a little hard to control but once you learn how to use it, the Basilisk is one of the most fun and deadly sidearms in MW2.

Best Perks to Use With M4 in MW2

The best Perks to use with the M4 in Modern Warfare 2 are:

  • Battle Hardened
  • Bomb Squad
  • Cold Blooded
  • Quick Fix

Find out how to unlock all of these perks here!

Best M4 Base Perks

The first Base Perk you should pick when running the M4 is Battle Hardened. As most players will be running Stun Grenades, it’s good to have this perk to reduce how long you are stunned.

For your second Base Perk, we suggest using Bomb Squad. This will help your survivability against enemy explosives.

Best M4 Bonus Perk

As a Bonus Perk, we think that Cold Blooded is always a great pick. After all, you don’t want a cheap death to an enemy AI killstreak!

Best M4 Ultimate Perk

Last, but not least, the best Ultimate Perk is Quick Fix. This is perfect for aggressive players as you recover health after every kill you get.

Best Equipment to Use With M4 in MW2

The best equipment you can use in your loadout with the M4 is:

  • Tactical – Stun Grenade
  • Lethal – Semtex

Stun Grenades are probably the most powerful tactical equipment in the game right now as they slow down enemies and make them easy targets. However, you can also choose to use the Stim very effectively with the M4 if you are an aggressive player.

We recommend using the Semtex as your lethal most of the time as it can reliably get you a lot of kills. Alternatively, Thermite can be a good lethal if you want to stop players from holding points in objective modes.

Best Field Upgrade to Use With M4

The best Field Upgrade to use with the M4 is Deployable Cover.

The Deployable Cover is perfect when you are running a long-range weapon as it lets you stay protected in any location of your choosing.

Plus, it is especially useful for taking objectives in game modes like Domination and Hardpoint.

Best Alternatives to M4

The M4 is one of the best all-around assault rifles in Modern Warfare 2 but if you want something with more damage, we suggest trying this meta Kastov 762 loadout! It has a bit more kick than the M4 but it kills a lot quicker if you are accurate!

You could also try these weapons:

  • TAQ-56 – A high fire rate AR with recoil that is easy to control when using the best TAQ-56 build in MW2. It’s probably the most similar to the M4 out of any weapon in the game, so M4 lovers may actually prefer it!
  • Kastov-74u – An assault rifle that is perfect for short and mid-range combat when you have the best Kastov-74u loadout.
