They are relatively easy weapons to use, making them a go-to weapon for any player. Assault rifles are the most versatile and reliable weapons in-game that are effective at all ranges. The numerous attachment options allow you to make them according to your playstyle.
Below you will find the best assault rifles which will elevate your gameplay.
Best Assault Rifles

The meta of Call of Duty Warzone changes with every patch. The new patch targets good guns with nerfs to balance out the game, but some guns never lose their charm. Assault Rifles are such weapons that all players must have in their loadouts.
Any loadout is incomplete without them. Listed below are the Best Assault Rifles in Call of Duty Warzone, which you can equip to perfect your loadout.
Grau 5.56

The Grau is one of the easiest guns to use, but that doesn’t make it any less of a threat. The high bullet velocity and low bullet drop-off with almost no recoil make it the best assault rifle at all ranges. This gun is already a menace, and the right attachments turn it into a nightmare for your enemies.
Best Grau 5.56 Loadout:
- Barrel: Tempus 26.4” Archangel
- Muzzle: Monolithic Suppressor
- Foregrip: Commando Foregrip
- Magazine: 60 Round Mags
- Laser: Tac Laser
The Grau has been subject to many nerfs in new patches. However, it still is a top contender for the Best Assault Rifles in Call of Duty Warzone. The proper customization brings Grau back to its former glory and makes it the beast it once was.
Tempus 26.4” Archangel increases your damage output at longer ranges and also provides an easier-to-use iron sight. With the Monolithic Suppressor, which also provides range and sound suppression, Grau can shoot enemies far away with precision.
The Commando Foregrip helps with recoil control, which is necessary to attach no scope to the gun. Iron sights are small and need more stability, which this attachment provides. Tac Laser further increases accuracy on hipfire, making Grau better for every situation.
60 Round Mags is important, as the huge number of bullets allows you to kill a whole squad. The probability relies on whether you hit your shots, but more bullets give more room for error. All these attachments together make Grau the perfect weapon for every encounter.
AK-47 (Cold War)

The AK-47 is the most dangerous weapon when in the hands of an experienced player. It has two variants in Warzone, the Modern Warfare, and the Cold War types. Both have different stats and attachments, but the Cold War variant is the one that shines.
It has a quickfire rate, heavy damage output at close to medium range, and better recoil control. The recoil gets out of hand at long ranges, but the right attachments decimate this effect. These aspects make it the better variant out of the two.
Best AK-47 (Cold War) Loadout:
- Muzzle: Suppressor
- Barrel: 20” Spetsnaz RPK Barrel
- Scope: Microflex LED
- Stock: KGB Skeletal Stock
- Magazine: 45 Rnd
The Suppressor increases the ADS speed and provides sound suppression, helping with accuracy and concealing your position. The ADS speed also increases impact at longer ranges, as you can see far away enemies slightly better.
20” Spetsnaz RPK Barrel significantly increases the bullet speed, range, and mobility. It decreases the recoil control, but the bullet velocity and range boosts cover that up. Besides this, the added mobility allows you to cover ground faster and shoot. This lets you get closer to enemies and have less room for error.
The KGB Skeletal Stock further increases your sprint to fire speed and ADS movement speed, enhancing your mobility. This allows you to react to any sudden fights or flanks by the enemy. During the earlier phase of the game, these attachments help you survive because of the speed you get.
AK-47 doesn’t have a lot of good options for magazines, and 45 Rnd is the best choice for you. It gives you additional bullets at the expense of reload speed. This isn’t a bad tradeoff as you can fire for longer with more bullets and won’t reload that often.
A scope like the Microflex LED is an ideal choice as it helps you see clearly at mid-range. The damage range of the AK-47 is best at this range, so this scope is perfect. Together, these attachments make this variant of AK-47 the best in the game.
M4A1

M4A1 is one of the earliest additions to the game that instantly became a fan favorite. The weapon was a prime choice for the multiplayer mode and dominated the charts in the earlier patches. It has been the target of nerfs recently, and many other guns are part of the game now.
However, it is still one of the Best Assault Rifles in Call of Duty Warzone when we properly customize it. M4A1 has a high rate of fire, good damage output, and an easy to control recoil. You can further enhance these stats with proper attachments and make this gun fatal for all your enemies.
Best M4A1 Loadout:
- Barrel: Stock M16 Grenadier
- Muzzle: Monolithic Suppressor
- Underbarrel: Ranger Foregrip
- Ammunition: 60 Round Mags
- Optic: VLK 3.0x Optic
The Stock M16 Grenadier drastically reduces your recoil and increases your damage output and range. It decreases your mobility, but the benefits are too good to ignore. Along with the Monolithic Suppressor, which also increases range and provides sound suppression, you can easily target enemies from afar.
The VLK 3.0x Optic compliments these boosts because it lets you see clearly while zooming the enemy. Furthermore, the Ranger Foregrip reduces recoil, which helps in targeting opponents at long range. All these attachments with the 60 Round Mags will shred your enemies with so many bullets at hand.
This loadout features to accuracy, range, damage output, recoil control, and sound suppression. Together, these allow you to wreak havoc upon your enemies.
XM4

XM4 is one of the most underrated weapons in Call of Duty Warzone. Since its release, it’s been in and out of meta but is now among the best after many buffs. Besides the buffs, perfect customization truly unlocks this weapon’s true potential.
Best XM4 Loadout:
- Barrel: 13.7” Extended
- Muzzle: Agency Suppressor
- Grip: Field Agency Grip
- Magazine: STANAG 60 Rnd
- Scope: Axial Arms 3x
The 13.7” Extended barrel significantly increases the bullet velocity of this gun, almost turning into a laser. This enhancement with the Agency Suppressor’s additional damage range and recoil control devastates your enemies. The Axial Arms 3x is just icing on the cake, as you can target enemies from afar.
The STANAG 60 Rnd gives you a lot more bullets to fire, which allows you to target more enemies. This, along with the Field Agency Grip, will enable you to destroy your enemies, as you have more recoil control. All these attachments complement each other well, as you can fight for longer periods without losing accuracy.
Assault rifles are easier to use but can cause destruction when you customize them properly. They are deadly weapons and can change the game if you use one according to your gameplay. Hopefully, this article on the Best Assault Rifles in Call of Duty Warzone helps you choose the best AR for you.
