First Citizen IX
From Destinypedia, the Destiny wiki
This machine gun belongs to an archetype that is in a difficult spot to judge. The high rate of fire should lend it well to PvP, but the naturally low damage and high recoil make it frustrating to control. In PvE, however, it is a different story. The First Citizen IX holds the highest inventory stat of any machine gun in the game, letting the player hold more rounds in reserve. By default, the total ammo supply is 256, but with both a Machine Gun Ammo Perk and Heavy Ammo Perk, that number goes up to 370. Combined with a large magazine size and surprisingly high accuracy, it becomes an excellent choice for delivering suppressive fire against waves of enemies.
