Let’s take a look at the bane of existence, the PVP God Roll Gnawing Hunger, a legendary void auto rifle. Gnawing Hunger introduced during Season of the Drifter but now re-introduced again during Season of Arrivals. The Gnawing Hunger is one of the greatest 600 RPM archetype in the game and is taking over the meta in the crucible. It melts players that peak like a sniper rifle. This flew to the top as one of the most hated weapons largely because it can also be equipped with, none other than, Mountaintop. I am going to say this now. If you have this combo and you lose. You should uninstall the game. No, but seriously play the game however you like. Just know you would be the most hated person in the game. The worst part of Gnawing Hunger, any perk combination works, but the right perk combination makes it shine. Here is the PVP God Roll for the Gnawing Hunger.

Barrel
Chambered Compensator increases stability by 9 for a total of 58. It also increases recoil direction by 10 for a total of 64. This will make the recoil pattern more vertically stable. Chambered Compensator decreases handling by 5 for a total of 62.
Magazine
Accurized Rounds increases the range by 9 for a total of 62.
Perk 1
Tap The Trigger. Grants a short period of increased stability and accuracy on the initial trigger pull.
Perk 2
Rampage. Kills with this weapon temporarily grant increased damage. Stacks 3x.
Mod and Masterwork
Stability masterwork increases stability by 9 for a total of 67. Rampage Spec increases the duration of Rampage by 1 second. It may not seem like a lot, but in 6V6 there is a lot of action everywhere. If you are in Competitive or Trials. I would go with Targeting Adjuster for increased aim assist.
Now you know the roll for Gnawing Hunger for PVP. The Gnawing Hunger has taken over the Crucible. It can be paired with Mountaintop making you the troll of the century. Have fun melting players and making them rage. Get to grinding Guardian.
