Best M4 Loadout in Warzone 2 – Meta Build, Attachments & More

The M4 is a staple of the Call of Duty series and is a great weapon to use in your Warzone 2 loadouts!

A very versatile assault rifle, the M4 can be effective at anywhere from short to losing range. However, to do this, you’ll need to know the right builds for the gun.

That’s why we’ve made 3 great M4 Warzone builds for Warzone 2.0 – one for long range, one for short range, and another which is made up of attachments that are easy to unlock!

The following 5 attachments increase the range and bullet velocity of M4 in Warzone 2.0, whilst decreasing its recoil.

  • Muzzle: Gauge-9 Mono – Unlocked at Kastov-74u Level 17
  • Barrel: Hightower 20″ Barrel – Unlocked at M4 Level 15
  • Optic: VLK 4.0x Optic – Unlocked at Kastov 764 Level 4
  • Ammunition: 5.56 High Velocity – Unlocked at STB 556 Level 7
  • Magazine: 60 Round Mag – Unlocked at M4 Level 17

So that you can unlock all of these attachments as quickly as possible, find out the fastest way to level up guns in MW2!

The Gauge-9 Mono is perfect for long-range combat as it increases your bullet velocity and recoil control. What’s more, it also suppresses the sounds of your gunfire!

The Hightower 20″ Barrel is the best M4 barrel for Warzone as it increases bullet velocity, damage range, and recoil control.

If you want pinpoint accuracy at long range without too much zoom, the VLK 4.0x Optic is a great choice. Of course, this is just a matter of preference though – use whatever optic you like the most.

If you prefer a closer-range optic, find out how to unlock the blue dot optic in MW2 and Warzone 2!

High bullet velocity is a must for any assault rifle in Warzone 2.0 so we’ve opted for the 5.56 High Velocity Ammunition.

Finally, you’ll need a lot of bullets to down a whole squad so the 60 Round Mag is almost essential for the M4 in Warzone 2.

Now, all you need to know is how to get loadouts and custom weapons in Warzone 2 so you can use this build in-game!

Best Sniper Support M4 Loadout in Warzone 2

If you are running the M4 as a sniper support weapon in Warzone 2.0, these are the attachments you should be using:

  • Muzzle: FTAC Castle Comp – Unlocked at 556 Icarus Level 10
  • Barrel: Hightower 20″ Barrel – Unlocked at M4 Level 15
  • Laser: FSS OLE-V Laser – Unlocked at EBR-14 Level 10
  • Optic: Cronen Mini Pro – Unlocked at Kastov 764 Level 4
  • Magazine: 45 Round Mag – Unlocked at M4 Level 5

This combination of attachments keeps the weapon’s mobility fast whilst also giving it some added range. Therefore, you’ll want to opt for this build to run alongside some of your long-range sniper rifles.

Of course, this loadout is not perfect, but it is certainly much better than the ground loot weapons you can find around Al Mazrah. We recommend trying to upgrade to an optic with a higher zoom as fast as you can though!

Best Secondary Weapon to Buy for M4 Loadout

The best secondary weapons to buy from a Shop after picking up your M4 loadout are high-damage SMGs like the Lachmann Sub or the PDSW 528. This is because they are much more mobile and kill quicker than the M4 at close range.

Alternatively, if you’re running a sniper support M4 build, you can’t go wrong with the SP-X 80 to get long-range headshots.

  • Lachmann Sub – A very strong SMG that hits hard and fires fast – perfect for close-quarters combat.
  • PDSW 528 – A SMG with a large magazine and an extremely rapid fire rate which is great for trios or quads game modes.
  • SP-X 80 – A powerful sniper rifle that balances damage, mobility, and range perfectly.

Best M4 Loadout Perk Package in Warzone 2

The Specter Perk package is the best for most Warzone 2 class setups and we recommend you equip it to your M4 loadout too.

In addition to Ghost, which keeps you off enemy minimaps after they call in UAVs, Double Time and Tracker can be useful for players who want to play aggressively or conservatively.

Specter contains the following Perks:

  • Double Time
  • Tracker
  • Spotter
  • Ghost

Best Equipment for M4 Loadout

We recommend using Semtex and Stun Grenades in your M4 loadout. Semtex is the best explosive equipment and Stun Grenades can be used offensively or defensively.

  • Semtex – A sticky explosive that can get you out of even more sticky situations.
  • Stun Grenade – A versatile piece of tactical equipment that suns any enemies nearby when it explodes.

Best M4 Alternatives in Warzone 2

The TAQ-56, Lachmann 556, and 556 Icarus are the best alternatives to the M4 in Warzone 2.0. They are all very similar to the M4 but have different qualities which many players may prefer.

  • TAQ-56 – Another solid all-around assault rifle that can be used at all ranges.
  • Lachmann 556 – An assault rifle with an extremely low recoil which is even more accurate than the M4.
  • 556 Icarus – The LMG in the M4 platform. Similar to the M4 but does more damage and has slightly slower handling.
