Locations[]

  • The ultra-light build mod may be crafted and applied to an armor piece at an armor workbench if the relevant plan is known. The combat armor torso mod can only be learned from scrapping pieces of combat armor.
  • Only loose ultra-light mods for the marine armor are randomly sold by Responder, Raider, Brotherhood, and Free States vendors. The marine mods can also be found in the Cranberry Bog.
  • The scout armor mods may only be sold by the MODUS armory terminal and aren't found elsewhere.

Notes[]

Unlike ultra-light mods for other armors, the metal torso mod doesn't require Armorer 3 to craft.
