Best M4 loadout in Warzone

The M4 is a classic and effective choice in Call of Duty, particularly in Warzone. Here’s our top M4 loadout for Warzone, including the most effective attachments and perks.

Warzone‘s Season 4 update is well underway, and the meta so far remains extremely similar to what we saw at the end of Season 3 Reloaded, with some classics coming back in popularity.

Success in Warzone comes down to picking the right weapon, and the M4 has already secured a spot in the meta as the safe, beginner-friendly, overall pretty good weapon. The classic Assault Rifle is one of Modern Warfare 2’s best guns and has quickly taken over Warzone’s Al Mazrah as well.

With a lethal TTK, an easy-to-control recoil pattern, and a solid damage range, you can’t go wrong with the M4 as your go-to AR in WZ.

Check out the best M4 loadout in Warzone below, along with the best combination of attachments, Perks, and equipment.


Best M4 Warzone loadout

  • Muzzle: Harbinger D20
  • Barrel: Hightower 20″ Barrel
  • Underbarrel: FTAC Ripper 56
  • Optic: Aim-OP V4
  • Magazine: 60 Round Mag
M4 in Warzone 2

We begin our best M4 loadout with the Harbinger D20, which improves the weapon’s bullet velocity while also suppressing the weapon. Then we’ve gone for the Hightower 20″ Barrel, for another boost to bullet velocity as well as general damage range.

Optics are mostly down to personal preference, but we like the Aim-OP V4 as it offers great accuracy at medium to long range. In the Underbarrel slot, we recommend the 5.56 High Velocity Ammunition, which improves the weapon’s firepower in long-range engagements.

Lastly, if you’re playing Warzone on squads, you’re going to need enough ammo to take down multiple enemies without reloading. That’s why we’ve picked the 60 Round Mags to help you dispatch as much of the opposing team as possible before having to change clips.

Best M4 Warzone class: Perks & equipment

  • Base Perk 1: Overkill
  • Base Perk 2: Bomb Squad
  • Bonus Perk: Resupply
  • Ultimate Perk: High Alert
  • Lethal: Semtex
  • Tactical Equipment: Flash Grenades

The first Perk is Overkill, which allows you to bring another primary weapon, such as an SMG or Sniper Rifle.

Explosives can end your match quickly if you’re not careful, so Bomb Squad is ideal for extra protection. Then, Resupply refills your own equipment every 30 seconds.

Al Mazrah is full of buildings for players to hide in, so it’s hard to spot every enemy team. Luckily, the Vanguard package features High Alert, which causes your screen to pulse when spotted by a rival player.

Equipment-wise, you can’t go wrong with Semtex to quickly flush a squad out of a building, paired with Flash Grenades to disorientate players before moving in for the kill.

How to unlock the M4 in Warzone

Luckily, the M4 is one of the guns available from the start in Warzone, so all you have to do is reach Level 4 to unlock Gunsmith and begin experimenting with loadouts.

Best M4 alternatives in Warzone

It may take some time for you to find the perfect weapon in Warzone, so if the M4 isn’t working you could switch to the TAQ-56 AR. Another powerful long-range AR, the TAQ-56 makes short work of foes with its strong damage output and top-tier stability.

But if you want something a little more mobile, the Kastov-74u could be the way to go. It’s absolutely lethal and is perfectly paired up alongside a meta sniper. While you won’t be beaming anyone from a distance with this trusty AR, it’s hard to outmatch this gun at medium range.
