History of Fluted Barrel

Fluted Barrel is a barrel perk described in game as an "ultra-light barrel" that greatly increases Handling speed and slightly increases stability.

Stats

Destiny 2 Wiki lists +5 Stability and +15 Handling for the base version; a search summary of light.gg adds an enhanced version at +6 Stability and +16 Handling. Note that the Destiny 2 Wiki's general Barrels comparison table instead shows +5 Handling, so sources disagree on the exact Handling figure.

Where it rolls

The Destiny 2 Wiki lists it on Auto Rifles, Pulse Rifles, Scout Rifles, Submachine Guns, Linear Fusion Rifles and Shotguns, for example MIDA Mini-Tool, Valakadyn and Gunnora's Axe. Compare Smallbore and Rifled Barrel.
