Armor ammo perks
Chest armor and boots can each raise this weapon's Inventory. Two +100 Heavy Weapon Ammo perks don't stack.
The bar shows the base value; the lighter band is the range this item's perks can reach. Exact amounts are shown where they're known (Inventory perks and armor ammo perks). For other perks Bungie's D1 data only says which way a stat moves (▲▼). Inventory is the hidden stat behind reserve ammo; it's only converted to a round count for rocket launchers, the one weapon type with published D1 numbers. Stats in italics were hidden in-game.
