The best Warzone 2 and Modern Warfare 2 M4 loadouts make this starting weapon reliable and easy to use for almost any situation. Owing to its versatility and sheer number of possible attachments, the M4 assault rifle is a solid choice from the best Warzone 2 and Modern Warfare 2 guns whether you're engaging the enemy at close, mid, or long-range in regular multiplayer or the massive Al Mazrah Warzone 2 map. You may already be familiar with the M4 as it's likely to be one of the first guns you've been killed by, since for many it will be part of their standard loadout so its use is widespread in multiplayer.
If you want an alternative assault rifle to the M4, then the best TAQ-56 loadout in Modern Warfare 2 is worth considering.
Still, if you want an edge against the competition, you'll be wanting to create the best M4 loadout in Modern Warfare 2 that you possibly can. And you can take things even further with M4 attachment fine tunes that can be made through Modern Warfare 2 weapon tuning - you can mess with everything from the ADS speed to the range of your barrel. You'll need to max the weapon level to get access to those options, but with this killer loadout it shouldn't take you long to get there. But in the meantime, here's the best Modern Warfare 2 and Warzone 2 M4 Loadout we've found so far after leveling the weapon to level 20.
Best Modern Warfare 2 M4 loadout – Aggressive
- Optic: Cronen Mini Red Dot
- Muzzle: FTAC Castle Comp
- Barrel: Hightower 20" Barrel
- Stock: Corio Precio Factory
- Rear Grip: XTEN Grip
- Receiver: M4
This is the best Modern Warfare 2 M4 Loadout that we've found so far, particularly for aggressive plays in the core 6v6 multiplayer offering. This MW2 M4 build is consistent at short and medium range encounters, with attachments like the Forge-Tac Castle Comp helping to keep your recoil under control. In a game as fast and as unforgiving as Modern Warfare 2, managing your recoil is especially important, particularly when dealing with close-quarters maps with short engagement ranges. Additionally, attachments like the XTEN Grip improve your sprint-to-fire and ADS, which pairs fantastically with the Cronen Mini Red Dot optic.
If you wanted to improve the control and versatility of this M4 build even further, you could consider swapping out the heavy Hightower 20" Barrel for the more lightweight 14" Carbine Shroud Barrel. If you're getting serious about recoil management, handling, and your ADS time, then that's something you should really think about – as is the Lockgrip Precision-40 under-barrel, rather than the Corio Precio Factory stock. All in all, this is a solid jack-of-all-trades setup for the M4 when it comes to classic Modern Warfare 2 modes.
Best Warzone 2 M4 loadout – Long Range
- Optic: SZ Lonewolf Optic
- Muzzle: Forge-Tac Castle Comp
- Barrel: Tempus Hightower 20" Barrel
- Underbarrel: VX Pineapple Vert Grip
- Stock: Demo Precision Elite Factory
- Receiver: M4
Whether you're jumping into Ground War and Warzone 2, or simply want a bit more range in the core 6v6 modes, you may want to consider this long-range M4 build. This is a heavier setup than the aggressive build, making you less viable in short-range encounters; recoil will hit like a hammer, but it's easier to control at range once you get going. Everything from the Hightower 20" Barrel to the VX Pineapple Vert Grip will severely impact your aim down sight and movement speed, but this loadout is all about getting in position and cutting enemies off as they attempt to clear distances with minimal cover.
In terms of the optic, there are really a lot of options here. Scopes are universally shared attachments in Modern Warfare 2, so feel free to go with what's comfortable. What I would say, however, is that you don't want to go for a marksman scope, even on this long range build – keep it versatile, something which can work comfortably across multiple engagement ranges, even if it does cost you a little ADS and aim walking movement speed.
Best Warzone 2 and Modern Warfare 2 M4 Class Build
- Secondary weapon: Hurricane (SMG)
- Tactical: Flash Grenade
- Lethal: Frag Grenade
- Field Upgrade: Deployable Cover
- Perk Package: Assault
In addition to your attachments, Modern Warfare 2 also lets you build out your own class – selecting a secondary weapon, alongside your perks, equipment, and more. While you are able to build out your own Perk Package – allowing you to mix-and-match Base Perks, along with a Bonus Perk and an Ultimate Perk which can be earned in match – you will need to level your character pretty significantly to get access to these options. If you're just starting out, we recommend you stick with the Assault Perk Package. However, do note that customizable Perk Packages are not available in Warzone 2 and you must choose one from eight options.
When you're starting out in Modern Warfare 2, stick with the basic Assault Perk Package, but when you start unlocking more perks for a custom package, we suggest choosing Overkill (Basic Perk 1), Scavenger (Basic Perk 2), Fast Hands (Bonus Perk), Quick Fix (Ultimate Perk). If you're opting for our long-range M4 loadout, the Assault Perk Package pairs nicely as it grants Overkill, which means you can carry a second primary weapon into combat. You'll want to pick up the FSS Hurricane, which is essentially the M4 as an SMG and is very good.
As for Warzone 2, we reckon the Commando Package is a fairly good compromise for our above suggestions. It should suit aggressive players well as Scavenger and Fast Hands are both included for rapid weapon handling and plenty of ammo. However, if Overkill is essential, your only option is the Weapon Specialist Package.
Use one of the loadouts listed here and you should be able to improve your Modern Warfare 2 KD, but if you want to maintain your accuracy then make sure you ADS in Modern Warfare 2 as much as possible.
