Below is our recommended M4A1 loadout. Our other weapon loadout guides can be found here.
The M4A1 is without a doubt one of, if not the, best Assault Rifles in Call of Duty: Warzone. The weapon is ridiculously powerful with the right attachments. Although the M4A1 has quite a kick to it, with the right configuration you can minimize its recoil to almost zero.
TOP GAMEPLAY HIGHLIGHTS & GUIDES
This guide will show you the best attachments for high accuracy, range and minimum recoil with the M4A1.
Note that we will be focusing solely on recoil control and not mobility. You are going to have significantly less mobility due to one of the attachments we recommend, but that attachment also gives you the most recoil control in this build.
We also have a video showing how well this setup does in-game.
The Muzzle you need to use for this build is the Monolithic Suppressor. It reduces your ADS and Aim Walking Steadiness but the change isn't that noticeable. The advantage of using this particular suppressor is sound suppression, but with a higher rate of damage.
The Monolithic Suppressor is unlocked when reaching Level 58 with the M4A1.
For the Barrel, you need to choose Stock M16 Grenadier. This barrel is an absolutely essential component of this configuration and is one of the main factors which contribute towards reduced recoil in your M4A1.
It gives you better recoil control, higher bullet velocity and a higher rate of damage. This Barrel will reduce your ADS and movement speed as a whole considerably. But, as stated before, the focus here is on recoil control. The speed debuff isn't too bad, it's just slower than the default.
You can also use Corvus Custom Marksman. It increases the same stats, but not as much as the Stock M16 Grenadier attachment. It does give a slightly higher movement speed, but the effective difference is negligible. The Stock M16 Grenadier is unlocked upon reaching Level 36 with the M4A1, and the Corvus Custom Marksman is unlocked at Level 59.
Go with the Ranger Foregrip here. It increases your recoil control and aiming stability with the M4A1 significantly. When we talk about aiming stability here, we're not just speaking about recoil control but also accuracy and damage range. An alternative is the Commando Foregrip, which just has a slightly lower range.
The Ranger Foregrip is available upon reaching Level 61 with the M4A1 whereas the Commando Foregrip is available early at Level 4, making it ideal at lower levels.
Choose Monocle Reflex Sight as your Optic. This scope is extremely precise and increases your accuracy at the cost of your ADS. Your ADS speed was already low due to the Stock M16 Grenadier however, and this reflex sight won't make much of a difference.
We were able to take out enemies shooting at us from the roof of the Stadium and other buildings, while we were situated at buildings much lower than theirs. It has extremely good accuracy and range.
The Monocle Reflex Sight is unlocked upon reaching Level 55 with the M4A1.
Rear Grip Or Ammunition
The last attachment is up to you. If you want even more recoil control for your weapon then go ahead and choose the Rubberized Grip Tape as your Rear Grip. However, if you already selected the attachments listed above, your effective recoil is already at the lowest the game allows, so it won't make a difference.
Therefore, if you don't want to constantly reload your weapon when engaging the enemies, go for Ammunition attachment and choose either the 50 Rounds Mag or the 60 Rounds Mag.
In our experience, this build can take down two opponents at most before requiring a reload, meaning any potential third opponent is at an advantage. If you are playing Solos mode, then that isn't a situation you'll often be in, so go for the Rear Grip attachment. However, for Plunder or Battle Royale 50 or 60 Rounds Mag attachments are essential.
The Rubberized Grip Tape is unlocked at Level 40, the 50 Rounds Mag at Level 24 and the 60 Rounds Mag is unlocked at Level 39.
