==Overview==
Weapon mods can be built from raw materials and attached to weapons at [[weapons workbench (Fallout 4)|weapons workbench]]es. There are over 700 mods,<ref>[https://twitter.com/Bethblog/status/610285077184933888 Bethblog Twitter]</ref> generally including sights, barrels, stocks, receivers, magazines and more. The [[Gun Nut (Fallout 4)|Gun Nut]] perk is required to create better modifications for [[Fallout 4 weapons#Guns|guns]]. The [[Science!]] perk is used to create better modifications for [[Fallout 4 weapons#Energy weapons|energy weapons]] and create advanced modifications for bullet based firearms. The [[Blacksmith]] perk is used to create better modifications for [[Fallout 4 weapons#Melee weapons|melee weapons]].

===Perks and weapon mods===
Most firearms, including energy weapons, offer the option to customize the grip/stock, receiver and sight, changing which perks affect the weapon.
* A firearm with an automatic receiver gets bonuses from the [[Commando (Fallout 4)|Commando]] perk.
* A firearm with a non-automatic receiver and pistol grip get bonuses from the [[Gunslinger (Fallout 4)|Gunslinger]] perk.
* A firearm with a non-automatic receiver and a stock mod get bonuses from the [[Rifleman (Fallout 4)|Rifleman]] perk.
* The [[Sniper (Fallout 4)|Sniper]] perk only works with a non-automatic firearm with a scope, which uses the "hold breath" mechanic.

Grip mods create pistol weapons, while stock mods create rifle weapons. This allows for almost any ranged firearm to be customized to fit the player's character build.

===Action Points and weapon mods===
''This section is based on research presented in YouTuber RedMage's [https://www.youtube.com/channel/UCfYbFsKcAPUSgOTdFkdkW1Q] video: "Fallout 4: VATS and AP Formula Solved!"[[10mm pistol (Fallout 4)|10mm pistol]]''

====The formula====
Attacking from [[Vault-Tec Assisted Targeting System|V.A.T.S.]] uses up [[Action Points]] (AP). There are three numbers that determine what the AP cost is for every type of modded weapon: the weapon's '''base AP cost''', the weapon's '''AP multiplier''', and the mod's '''AP effect''', and they do it based on this formula:

:'''''weapon base AP cost''' + '''(weapon AP multiplier''' x '''mod AP effect)'''''

Each weapon has a different '''base value''' of action points that it uses per shot. For instance, a 10mm bare receiver costs 21 AP per shot in V.A.T.S., so its AP base value is 21. 

Each type of weapon also has an '''AP multiplier''' that determines how much effect mods have on the AP of that type of weapon. [[Combat shotgun (Fallout 4)|Combat shotguns]], for instance, have an AP multiplier of 1.75, while [[Laser gun (Fallout 4)|laser guns]] have an AP multiplier of 1.25, meaning mods applied to combat shotguns will have a greater impact on AP (up or down) than mods on laser guns.

Finally, each mod has an '''AP effect''', which is how strongly it changes the weapon's AP cost. There are some general patterns to how strongly the mods affect all gun types, but it's inconsistent. For instance, the [[Reflex sight (Fallout 4)|reflex sight]] has a consistent -3 effect on all gun types tested, but the [[Long barrel (Fallout 4)|long barrel]] mod has an effect of +1 on 10mm pistols, but +4 on [[Hunting rifle (Fallout 4)|hunting rifles]].

;Example
A combat rifle (base AP cost = 22.5; AP multiplier = 1.25) with reflex sight (AP effect = -3):
:''22.5 + (1.25 x -3) = 18.75 AP cost per shot''

==Notes==
* Each time a new mod is built, the [[Sole Survivor]] receives a small amount of [[Experience Points|XP]].
* Building weapon mods replaces the current mod applied to the weapon, the replaced weapon mod is stored in character's [[inventory]]. Attempting to craft a weapon mod which is already present in the character's inventory will apply the mod from the character's inventory instead of using material (no XP is earned).
* Mods stored in a [[workshop (Fallout 4)|workshop]] can be reused, and they will be available at all other settlements connected by a [[supply line]]. Mods can also be stored in containers. 
* Every disassembled weapon mod has a weight of 0.5.
* Mods purchased from merchants may be reused an unlimited amount of times on as many suitable weapons as one wishes. The breakdown resource value for the weapon will reflect the addition of the mod.
* [[Codsworth]] and [[Danse|Paladin Danse]] will love it when the player character creates weapon mods, and [[Preston Garvey]] likes it.
* Unlike [[Fallout 4 armor mods|armor modifications]], most weapon mods cannot simply be removed from a weapon except for muzzle modifications. They must be replaced with an available or a newly created modification before the desired mod will be put into the [[Sole Survivor]]'s inventory. Should the Sole Survivor not have the skill or resources to create the higher tier mods, the mod on an acquired weapon may be replaced with standard mods with fewer resources expended and no skills required.
* Each mod may have up to eight qualities describing the magnitude of the mod's effect on weapon stats. These qualities are always sorted in descending order in the mod's description, ranging from big bonus to big penalty: Exceptional - Superior - Better - Improved - (Standard) - Worse - Reduced - Inferior - Poor
* The ''[[Nuka-World (add-on)|Nuka-World]]'' add-on includes new melee weapon mods that include rockets (like the super sledge) along with weighted and heating coil mods.
