Best M4 MW2 loadout
- Muzzle: RF Crown 50 (+0.49, +0.00)
- Barrel: 11.5″ T-H4 Barrel (-0.26, -0.40)
- Optic: Cronen Mini Pro (-3.00, +0.00)
- Stock: Tempus P80 Strike Stock (+2.74, -1.16)
- Rear Grip: Sakin ZX Grip (+0.81, +0.00)
Even when left stock the M4 is already a versatile assault rifle without many flaws. This gives us the freedom to build it how we want. To suit multiplayer’s fast pacing it’s best to optimize for mobility while also looking to reduce the M4’s recoil where possible.
For recoil control, we use both the RF Crown 50 and Sakin ZX-Grip. These combine to significantly reduce recoil and make the M4 more accurate during sustained fire. In saying that, this M4 loadout is more suited to the shorter sightlines found in 6v6 than the likes of Ground War and Invasion.
To improve mobility it’s recommended to use both the Tempus P80 Strike Stock and 11.5″ T-H4 Barrel. The barrel improves ADS speed without any notable downsides making it a good choice for any build. Meanwhile, the stock massively improves ADS strafe speed, and tactical sprint speed.
The final attachment is the most flexible but we’ve opted for the Cronen Mini Pro to provide the clearest optic possible. Those comfortable with the M4’s iron sights should consider a suitable underbarrel or mobility improving laser instead.

M4 MW2 loadout: Perks & Equipment
- Base Perk 1: Tracker
- Base Perk 2: Battle Hardened
- Bonus Perk: Fast Hands
- Ultimate Perk: Ghost
- Lethal: Proximity Mine
- Tactical: Snapshot Grenade
For our Base Perks, we’ve chosen Tracker and Battle Hardened. Tracker can detect enemy footsteps and allow you to hone in on their whereabouts for an easy kill, whereas Battle Hardened is terrific for reducing the effects of all those pesky tactical grenades that will inevitably come your way.
The best Bonus Perk to use with this M4 loadout is Fast Hands. Fast Hands greatly improves reload sped minimizing the time spent standing around waiting for the animation to finish. On such an aggressive build it’s essential that you can reload as fast as possible.

Finally, we’ve gone for Ghost as our Ultimate. It’s arguably the best perk in Modern Warfare 2 and is just perfect for any player no matter their play style.
The Proximity Mine and Snapshot Grenade round things out here as the Mine is a constant menace and is especially great for objective-based modes. On the other hand, the Snapshot Grenade is priceless for revealing the enemy’s position giving you more intel to play with.
How to unlock the M4 in Modern Warfare 2
Thankfully, there is no need to grind to unlock the M4 as it is available from the start of your Modern Warfare 2 multiplayer journey.

Alternatives to the M4 MW2 loadout
If you find that the M4 doesn’t quite cut it for you, then there are other options for you to try out such as the Lachman-556, which is just as versatile in all situations.
However, if you want something that packs more punch, the TAQ-56 is a fantastic option with it being the most used gun in MW2 and dominating Ranked Play loadouts.
