Weapons workbench (Fallout 4)

The weapons workbench is a crafting station in Fallout 4.

The Sole Survivor can use the workshop to attach and detach weapon mods.

When applying a weapon mod, the name of the weapon can change, even allowing to turn into a better variant, like making rifles from pistols. One can also choose to rename a weapon themselves.

To create a mod, specific materials are required, as well as the corresponding perks, Gun Nut for guns, Blacksmith for melee weapons and Science! for energetic weapons. Some mods requires two of the perks at once, such as night vision scopes mods for sniper rifles.

There are two different looking versions of the weapons workbench found in Fallout 4. However, they are functionally identical in every way, and thus it does not matter which one is used under any circumstance.
