For the first gun you unlock, the best Warzone M4 loadout can carry you a long way. With the right attachments the Warzone M4A1 give you a range of powerful and varied options. It's a versatile gun in Call of Duty Warzone. The Warzone M4 is just an incredibly well rounded gun that can be kitted out to deal with anything from close quarters combat to longer range engagements. You can even get a sweet spot between the two if you load it out just right. With that in mind these are the best M4 loadouts in Warzone.

Best Warzone M4A1 builds

When playing Warzone, there's different aspects of the game you need to take into consideration. Rather than explaining all of the correct attachments to use in Warzone – every style of play listed below is viable, after all – here are some suggestions for how to set up the entire class.

The key perk you want to have on your M4 Warzone class is Overkill. This will allow you to either cater your M4 to close quarters combat or long range play, depending on what your second weapon is. If you opt for a kitted out SMG – the MP5 would be our choice – you'll want a longer scope on your M4, along with attachments that help you retain damage and recoil control at range. Use the accuracy build below for your M4 if this is your choice.

If you're not sold on the M4 then check out some other options with Warzone best guns.

On the other hand, if you want to keep your M4 as a close-medium range weapon, equipping a marksman or sniper rifle as your secondary would be smart. Something like the Kar98K or HBR, especially with a thermal scope, can be devastating in Warzone. Something like the run n gun build below would be ideal for the M4.

For the other perks, in the first slot we'd recommend considering either Scavenger or Double Time. The former is very useful if you're burning through lots of ammo, while sprinting faster can be useful if you don't want to use a vehicle and need to cover lots of ground. In slot three, consider using Shrapnel. No matter which lethal you opt for, having two of them is incredibly useful when clearing out buildings, especially when the safe zone is much smaller.

Our first of the Modern Warfare best M4A1 builds comes courtesy of Ian "Crimsix" Porter, one of the most decorated and successful Call of Duty pro esports players in the world. Having recently moved to Dallas Empire for the upcoming league, his M4A1 loadout focuses on sacrificing mobility for accuracy, ensuring the gun deals as much damage as possible at range.

If you love playing slowly, sitting in corners and pre-aiming doors for enemies to come barreling through, take a look at out stealth-focused build. With this, you'll be able to push for the high killstreaks, especially if you utilise things like the Heartbeat Sensor and Ghost perk.

Underbarrel: Bipod

Best Warzone M4A1 run n gun loadout

For playing fast and frantic, I'd usually suggest rocking an SMG like the MP5. The M4A1 is so good however, that it can be used more than effectively in close quarters combat situations with a build like this, and relies a lot on hip fire kills up close.

Laser: 5mW Laser
Optic: G.I. Mini Reflex
Stock: No Stock
Rear Grip: Stippled Grip Tape
Underbarrel: Merc Foregrip

Sometimes you just want to play as a standard assault soldier who can dabble in all sorts of situations. For that, you'll want this M4A1 build which can perform at range, up close, and everything in-between. The only thing you're sacrificing here is mobility, so while you'll be more than adept in close quarters combat, don't go barging into rooms full of enemies.

Barrel: Corvus Custom Marksman
Optic: Integral Hybrid
Perk: FMJ
Ammunition: 60 Round Mags
Underbarrel: Ranger Foregrip
