Best M4A1 Warzone loadout class: Attachments, Perks, Setup

M4A1 Blueprint in Modern Warfare's GunsmithInfinity Ward

The M4A1 has always been a consistent weapon but it fell out of the meta in favor of newer and more popular Vanguard ARs. The M4A1 is back and better than ever after the Warzone Season 4 update. 

No gun comes close to reaching the popularity status of the NZ-41, but the M4A1 perfectly fits the current long-range AR meta. 

Although there are other long-range options, such as the STG44, Cooper Carbine, and Kilo 142,  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.

It’s not hard to see why the M4A1 has remained a staple pick.


  • Muzzle: Monolithic Suppressor
  • Barrel: Stock M16 Grenadier
  • Optic: VLK 3.0x Optic 
  • Underbarrel: Commando Foregrip 
  • Ammunition: 60 round mags


  • Perk 1: Double Time
  • Perk 2: Ghost
  • Perk 3: Combat Scout 


  • Tactical: Heartbeat Sensor
  • Lethal: Semtex 

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 Commando Foregrip, which will augment your recoil control and maximize your efficiency in distant gunfights.

This will be complemented by the 60 round mags, which enable you to take on multiple players simultaneously, without the need to stop and reload. 

Finally, the VLK 3.0x Optic 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.
