The M4A1 has been a consistent assault rifle in Warzone since the game’s release, but it has recently taken a backseat in the meta. Despite this, the weapon still packs a punch and with the right loadout, it can be deadly at medium range.

With the likes of the Krig 6 and the Kar98k dominating Warzone, it can be difficult to find an alternative assault rifle that’s effective at medium range.

Although there are a few options, Modern Warfare’s M4A1 is always a solid choice. While it may not be the top-tier meta weapon at the moment, it’s always reliable and can be incredibly effective with the correct setup.


Without further ado, let’s check how you can unlock and kit out your M4A1 to get the most out of the gun.

Best M4A1 Warzone loadout


  • Muzzle: Monolithic Suppressor
  • Barrel: Stock M16 Grenadier
  • Optic: G.I. Mini Reflex
  • Underbarrel: Merc Foregrip
  • Ammunition: 50 round mags


  • Perk 1: E.O.D
  • Perk 2: Ghost
  • Perk 3: Amped


  • Tactical: Heartbeat Sensor
  • Lethal: Grenade

First up, you’ll notice the Monolithic Suppressor and Stock M16 Grenadier. These attachments will offer a significant boost to damage range, as well as stabilizing shots to a significant degree. Not to mention a suppressor is key in the battle royale environment to remain undetected.

Next up is the Merc Foregrip, which will augment your recoil control and maximize your efficiency in distant gunfights.


This will be complemented by the 50 round mags, which enable you to take on multiple players simultaneously, without the need to stop and reload. Although you could use 60 round mags, the weight increase isn’t worth the extra 10 shots.

Finally, the G.I. Mini Reflex is one you can swap out for a different sight if you prefer. We’re just recommending optics in this class because the M4A1’s iron sights aren’t ideal for long-range engagements.

How to unlock the M4A1 in Warzone

The M4A1 is extremely strong in medium-range gunfights.

The M4A1 is available for Warzone players to use as soon as they start the game as it is unlocked at level 1. Although there are no requirements to use the assault rifle, you will need to unlock the best attachments for the gun.


You can do this by playing in matches and completing the various challenges associated with the weapon. Once you have done so, you’ll need a top-tier loadout to get the most out of the weapon.

Luckily, below you can find what we think is the strongest M4A1 loadout in Warzone at the moment.
