With Season 4 of Black Ops 6 and Warzone now live, those who didn't get the Grau in Season 3 will have to follow different steps to get the weapon.

The weapon from Modern Warfare (2019) was added along with the return of Verdansk, and since it remains a top option in the current meta, many will probably try to unlock it to take advantage of it. For those who are not familiarized with unlocking weapons, we have prepared a guide explaining what you need to do.

The Grau is not a separate weapon in Black Ops 6 and Warzone, since players need to get the conversion kit for the SWAT 5.56 to turn the marksman rifle into the Grau.

The only way to unlock the Grau conversion kit is through an armory unlock, which is the main method to unlock items from past seasons. The kit was previously available as a reward of the Season 3 battle pass, but this has expired.

To do this, start either Black Ops 6 or Warzone and head to the Barracks tab at the top.

From there, select the "Challenges" option from the menu at the bottom. Once inside, you will see the Armory option amongst the list.

Go into the armory, and inside, you will see a list of the different items you can unlock. Since you can only unlock one item at a time, you only have to select the Grau Conversion Kit to start progressing its unlock bar. The kit should be one of the options under the Attachment category.

Once you find it, set it as your current unlock, and then you will have to earn 150k XP points to get it. You can earn XP doing pretty much anything, so the only thing left would be to play until it's done.

After that, just create a loadout with the SWAT 5.56 and select the conversion kit in the Fire Mods slot from the gunsmith screen.
