Drum magazine (Fallout 76)

Drum magazine is a weapon mod for several weapons in Fallout 76.

Effects
When applied to a weapon, the mod greatly increases the weapon's total magazine size, allowing more shots to be fired before reloading. It is the default magazine mod for the light machine gun and can't be crafted.

Crafting

 * 10mm submachine gun


 * Assault rifle


 * Combat shotgun


 * Gauss pistol


 * Handmade rifle


 * Pipe gun

Location
The drum magazine mod may be crafted and applied to weapons at a weapons workbench if the relevant plan is known. With the exception of the 10mm submachine gun, the mod can only be learned from scrapping weapons of the same type.
