Call of Duty: Modern Warfare Season 4 Update Nerfs Grau and MP5

The mid-season update for Call of Duty Modern Warfare and Warzone is now out as of 11 pm PT on June 29. Aside from exciting new 200 player Battle Royale Quads in Warzone, several weapons got various nerfs and buffs. The primary weapons seeing nerfs with this update are the Grau 5.56 and the MP5.

Call of Duty Modern Warfare Grau Nerf

Many players anticipated a Grau nerf this season, considering it’s still the most popular assault rifle in everyone’s loadout. The main nerfs hitting this AR are damage range reductions and slightly more high-frequency recoils. We also see the Tempus 26.4″ Archangel and the FSS 20.8″ Nexus barrels getting less recoil compensation and less range. 

Warzone Season 4 MP5 Nerf

As for the MP5, this popular submachine gun gets a decrease to its damage range, decreased 10mm damage range, reduced long-range damage for 10mm ammo, and more recoil on 10mm ammo. In short, this means more recoil and a higher time-to-kill. 

Considering these two weapons are the most popular choices in Warzone, we may see the meta get shaken up. Players will likely take a day or two to adjust to the new changes before revealing the next best Warzone loadouts

Weapon Buffs and Nerfs

While some weapons got hit with some pretty big nerfs, others are seeing a few buffs. The MK2, for example, has faster movement speed and damage range now. The Dragonuv, one of the most underutilized snipers in the game, now has faster ADS and a higher fire rate. These buffs and nerfs apply to both the Modern Warzone multiplayer and Warzone battle royale.
