M4A1 has always been a weapon of choice since the beginning of Call of Duty: Warzone. The Modern Warfare Assault Rifle features a fast fire rate, good range, and moderate damage. Here's a guide on how to build three of the best M4A1 loadout variants in Warzone Pacific.
Best M4A1 Loadout Warzone for Long-Range
- Muzzle: Monolithic Suppressor
- Barrel: Stock M16 Grenadier
- Optic: VLK 3.0x Optic
- Underbarrel: Commando Foregrip
- Magazine: 60 Round Mags
These are the best M4A1 attachments required for a class that shreds enemies over distance. This build gives the weapon its maximum damage range and bullet velocity while taking a hit on its mobility. You can pair this no-recoil M4A1 build with a mobile, fast-firing Submachine Gun.

Best M4A1 SMG Loadout Warzone
- Barrel: FSS 12.4" Predator
- Laser: 5mW Laser / Tac Laser
- Stock: No Stock
- Underbarrel: Commando Foregrip
- Magazine: 9mm Para 32-Round Mags
The attachments used here are for a close-quarters M4A1 build that is extremely viable in Rebirth Island. We have focused on boosting the mobility and fire rate by sacrificing the bullet velocity. Another thing to keep in mind is that you run out of bullets pretty quickly using the 9mm magazine.
For the laser attachment, use the 5mW Laser for better sprint-to-fire time and hipfire. Alternatively, you may use the Tac laser for faster aim-down-sight (ADS) speed. Although you can pair this with a Sniper Rifle in Rebirth, try out the next loadout for a game in Caldera.
Best M4A1 Sniper Support Loadout
- Muzzle: Monolithic Suppressor
- Barrel: Corvus Custom Marksman
- Optic: G.I. Mini Reflex
- Underbarrel: Commando Foregrip
- Magazine: 50 Round Mags
For our final loadout recommendation, we've showcased the best sniper companion AR. Unlike the previous SMG build, this M4A1 loadout doesn't sacrifice its range. It is quite similar to our first build but with slightly better ADS and movement speeds.
Best M4A1 Class Setup Warzone
- Primary Weapon - M4A1
- Secondary Weapon - OTs 9 / Welgun / Kar98k (Modern Warfare)
- Lethal - Throwing Knife
- Tactical - Heartbeat Sensor
- Perk 1 - Cold Blooded
- Perk 2 - Overkill
