History of Gun-believable

Overview

Gun-believable is a gilding Triumph of the Sharpshooter seal in Destiny 2. It requires completing a dungeon, a Raid or Portal Ops at Master difficulty or higher while a Volatile Weapon mod is equipped.

How to complete

1. Obtain the current Arms Week Volatile mods. They drop as Engrams from enemies in Portal activities.
2. Equip a Volatile mod on a weapon of the featured category. Mods appear at the top of the weapon mod list.
3. Run a dungeon, raid or Portal Ops at Master difficulty. The mod must be active when the activity completes.

Tip: Volatile mods work only during their own Arms Week, and they do not work in the Desert Perpetual raid. Old mods from a previous Arms Week may not count.
