Modern Warfare & Warzone: GRAU 5.56 Loadout, Best Attachments And Setup For Your Class

GRAU like a warrior

Have you considered using the Grau?

The Grau 5.56 still remains one of the strongest weapons across multiplayer and Warzone.

Despite being hit by a few nerfs in past updates, players are still falling back to this weapon for its reliability, damage and accuracy.

It also boasts a strong rate of fire and clean iron sights (freeing up an attachment slot).

Here are the best GRAU classes in Warzone and Modern Warfare.

1) The Perfect Warzone Class

The first GRAU class is perfect for most scenarios that you will encounter during a game, including Warzone.


  • Monolithic Suppressor (Muzzle)
  • Tempus 26.4" Archangel (Barrel)
  • Tac Laser (Laser)
  • Commando Foregrip (Underbarrel)
  • 60 Round Mags (Ammunition)

This set of attachments is perfect for any situation, providing a strong damage output, minimal levels of recoil and a crisp iron sight to keep your target in focus regardless of range.


  • Double Time (Perk 1)
  • Ghost (Perk 2)
  • Spotter (Perk 3)

These perks are interchangeable depending on your playstyle, but in Warzone they are the better choices in Warzone.


  • C4 (Lethal)
  • Stun Grenade (Tactical)

A stun grenade and C4 combination will be lethal when try to tackle multiple enemies.

Field Upgrades

  • Deployable Cover

Perfect for blocking a doorway or providing some cover in an open area, deployable cover can be used when defending objectives or as a last line of defence before the enemy advances on your position.


  • Counter UAV (4 Kills)
  • Sentry Gun (7 Kills)
  • VTOL Jet (8 Kills)

This particular streak combination is great for confusing the enemy and providing plenty of cover across various areas of the map.

2) Unmatched Aggression

This class is designed for aggressive Assault Rifle (AR) players to deal some serious damage whilst getting heavily involved in the pandemonium.

GRAU 5.56 class guide


  • FFS 20.8” Nexus (Barrel)
  • FSS Blackjack (Stock)
  • FTAC R-89 Rubber (Rear Grip)
  • FMJ (Perk)Cronen Shark II (Underbarrel)
  • Cronen Shark II (Underbarrel)

The choice of barrel is the key for dealing the most amount of damage. Selecting the nexus increases the damage output considerably and hardly takes away any mobility, making this iteration of the GRAU deadly in amongst the action.


  • EOD (Perk 1)
  • Hardline (Perk 2)
  • Battle Hardened (Perk 3)

Both EOD and battle hardened provide increased resistance to lethal and tactical equipment which is a must when entering action-packed areas of the map filled with players. Hardline is also perfect for this class as it means killstreaks take one less kill to earn, meaning you can score them quickly without having to alter an aggressive style of play.


  • Semtex (Lethal)
  • Smoke Grenade (Tactical)

The Semtex is great for clearing out a congested objective. Throw the smoke beforehand and see the opposition-run for cover as they try to avoid the Semtex and escape the dense smoke that has descended upon them.

Field Upgrades

  • Trophy System

When playing the objective, place the trophy system down as an additional form of cover to block any form of incoming grenades that will try to force you to change position or abandon control of the objective altogether.


  • Personal Radar (3 Kills)
  • Cruise Missile (5 Kills)
  • Infantry Assault Vehicle/Wheelson (7 Kills)

The party piece of this streak combination is the IAV which can be used on some of the bigger maps in Modern Warfare. Take control of a huge tank and decimate the enemy!

3) Small But Mighty

The third and final class may look like an underpowered sub-machine gun but in fact, this version of the GRAU packs a lethal punch in close-quarters, making it perfect for all out rushing.

GRAU 5.56 best class


  • ZLR Drifer A-08 (Barrel)
  • No Stock (Stock)
  • Sleight of Hand (Perk)
  • XRK Void II (Rear Grip)
  • 60 Round Mags (Ammunition)

This set of attachments converts the GRAU into a compact and mobile AR that can easily content with some of the stronger SMGs in the game. It’s most effective when getting involved in all the action so for the best results, get stuck in!


  • Double Time (Perk 1)
  • Pointman (Perk 2)
  • Tracker (Perk 3)

Double time allows your tactical sprint to recharge faster and doubles its length, allowing you to navigate the map quickly. Pointman converts killstreaks into scorestreaks, perfect for playing the objective and tracker enables you to see where the enemy has been with bright red footsteps lighting up the way to an easy kill.


  • Frag Grenade (Lethal)
  • Stun Grenade (Tactical)

Use the stun grenade to slow the enemy down, making them an easy target and use the frag grenade to either launch across the map in the hopes of scoring a crazy hail Mary kill or cook it and bounce it into a crowd for a massive impact.

Field Upgrades

  • Stopping Power Rounds

Further increasing the lethality of the GRAU with some stopping power rounds to make it even more deadly at close range.


  • Cluster Strike (5 Kills)
  •  VTOL Jet (8 Kills)
  • Advanced UAV (12 Kills)

The cluster strike and VTOL can easily secure a hefty number of kills while the advanced UAV provides some support for your teammates, revealing the location and real-time movements of the opposition.
