If you're hunting for Warzone wins you need the best M4A1 loadout. This assault rifle will see you through close quarters combat, as well as firefights at longer ranges. While it isn't as flashy and exciting as the recently added Cold War weapons, it's still a reliable and balanced gun that'll get the job done in battle royale matches.

With new weapons frequently being added to Warzone, it's always a good idea to refresh your setups to remain competitive. Whether your game plan involves being stealthy, or you prefer to chase after opponents aggressively, I've selected some builds that are sure to fit your playstyle. Here are four of the best M14A1 loadouts, when to use them, and the attachments you'll need to unlock before piecing them together.

The best Warzone M4A1 loadout for all situations

Reliable all-rounder

Attachments

  • Barrel: Stock M16 Grenadier
  • Optic: Operator Reflex Sight
  • Stock: No Stock
  • Underbarrel: Commando Foregrip
  • Rear grip: Stippled Grip Tape

Extending range and increasing recoil control.

  • Kar98k

Perks

  • E.O.D
  • Overkill
  • Amped

Throwables

  • Lethal: Frag Grenade
  • Tactical: Flash Grenade

This build is well-rounded and versatile. It holds its own at mid and relatively long ranges, so it's perfectly viable at any point in a match. 

The Stock M16 Grenadier is a handy barrel as it increases your damage range, while bumping up the weapon's accuracy and lowering recoil. Smoother handling at mid ranges is handy, but you also want to actually see your enemy as you send them to the Gulag: the Operator Reflex Sight is a worthy choice for that as it's clean and minimal, and helps you get the job done. Add an extended magazine to this build if you want, but it's worth mentioning that the Commando Foregrip already reduces your movement speed. 

Low profile

Monolithic Suppressor

The perfect muzzle for a stealthy build.

  • Muzzle: Monolithic Suppressor
  • Barrel: Stock M16 Grenadier
  • Optic: Thermal Hybrid
  • Stock: Singuard Arms Invader
  • Underbarrel: Bipod

Secondary

  • 1911

Perks

  • Cold-blooded
  • Ghost
  • Tracker

Throwables

  • Lethal: Claymore
  • Tactical: Smoke Grenade/Heartbeat Sensor

Of course, a suppressor is an essential addition to this stealthy build. Always go for the Monolithic Suppressor over the Lightweight option, as compromising your damage range just isn't worth it.

A stealthy build must be paired with a slow and patient gameplan, and these attachments support that style. The Bipod underbarrel is useful for following another player and steadily taking them out, while also adding crouch and prone recoil control. 

Quietly holding angles naturally falls into the approach you take with this build, and the Tracker perk makes it easier to stalk your prey. The Singuard Arms Invader increases your walking movement speed while aiming, and the Commando Foregrip helps you to eliminate opponents quickly by stabilising your aim.

Steady hand

Attachments

Granulated Grip Tape

A grip for accurate, controlled shots. 

  • Barrel: Corvus Custom Marksman
  • Optic: Cronen LP945 Mini Reflex
  • Stock: M-16 Stock
  • Underbarrel: Operator Foregrip
  • Rear grip: Granulated Grip Tape

Secondary

  • MP5

Perks

  • E.O.D
  • Overkill
  • Spotter

Throwables

  • Lethal: Semtex
  • Tactical: Snapshot Grenade

This M4A1 Warzone loadout focuses on accuracy, so your movement speed is noticeably reduced. The Corvus Custom Marksman barrel reduces aim-down-sight and movement speed, but stabilises your shots while adding range. Granulated Grip Tape further aids the precision and steadiness of your shots. 

This loadout is for you if you're confident in your aim: your reduced mobility makes it harder to escape if you mess up. Expect to win longer range firefights though, if your reflexes are up to scratch. 

Your tactical and lethal slots help to deal extra damage, with the Snapshot Grenade briefly revealing where your opponents are lurking (within it's blast radius). Remain alert at all times and you're bound to rack up eliminations from just a few bursts of devastating shots.  

Aggressive

Attachments

50 Round Mags

More rounds to take out more enemies.

  • Barrel: Stock M16 Grenadier
  • Optic: Viper Reflex Sight 
  • Stock: M-16 Stock 
  • Underbarrel: Commando Foregrip
  • Ammunition: 50 Round Mags

Secondary

  • 725

Perks

  • Double Time
  • Overkill
  • Amped

Throwables

  • Lethal: Semtex
  • Tactical: Stun Grenade

Warzone's map is huge, with stretches of open land where snipers can pick off other players for fun. So an aggressive playstyle may not be the most advisable way to operate in the lull that occurs halfway through the match, but as the gas closes in, this is the best M4A1 loadout in Warzone to help you dominate the late game.

The M-16 Stock boosts your aiming stability, which makes your AR feel more reliable. While attaching the 50 Round Mags extended magazine reduces your movement and aim-down-sight speeds, the additional ammunition is beneficial for extended battles. As always, optics are important, and the Viper Reflex Sight is a small, no thrills sight that's simple to use.
