  • The perk is needed to craft mods from scratch, not for applying or removing mods. One can remove a mod and apply it freely on the same kind of weapon, even if one could not build a new copy of that mod.
  • With the Automatron add-on, one point in Gun Nut is required to access the full range of craftable robot components at a robot workbench.
  • With the Contraptions Workshop add-on, leveling up Gun Nut allows the player character to access most of the range of ammunition recipes at an ammunition plant via a terminal.
  • The loading screen uses the Fallout 3 Gun Nut perk icon as a pin badge.
