This page lists all Fallout: New Vegas weapon mods.
Overview
One of the features added to Fallout: New Vegas is the ability to custom modify certain base weapons. While in Fallout 3 this was limited to the creation of custom weapons, Fallout: New Vegas takes this a step further by allowing the creation of weapon variants based on basic weapons by adding weapon mods.
Unique weapons cannot be equipped with weapon mods, with the exception of the Weathered 10mm Pistol, the Mercenary's Grenade Rifle and the Holorifle. While unique guns usually have better base stats, Obsidian Entertainment introduced this inherent drawback of unique weapons to balance out unique and normal weapons and make the choice less of an obvious decision and more of a preference. However, some unique variants have both mods and better base stats. Such is the case of the Varmint Rifle's unique variant, the Ratslayer, which has all of the mods the Varmint Rifle can be equipped with.
By themselves, the weapon mods are weightless and serve no function but, once attached to their specified weapon, will change the characteristics, look and/or function to create a distinct variant. The weapon mods range from scopes and silencers to extended mags and several in-between. In the case of the Varmint Rifle and other such weapons there exists more than one different type of modification. While the player is not limited in the amount of total mods they can apply to a single weapon, they are limited to one of each type of mod per single weapon and therefore are not able to stack attributes like increased rate of fire.
Once a weapon mod is attached to a weapon it cannot be removed and remains a permanent feature of that weapon, along with its added attribute. However, this might not always be a good thing. For example, extended magazines are almost always beneficial, unless the magazine must be reloaded on a shell by shell basis (ex: Cowboy Repeater), forcing a longer reload (not necessarily forcing the reload to be longer, since pressing the fire button stops the reload); scopes also have pros and cons, as they may increase maximum range, but make the gun harder to use in close combat situations.
The addition of a mod to a weapon will permanently increase the overall monetary value of that weapon by the value of the mod, even if the weapon is completely broken at the time it is applied.
Usage
Weapon mods are attached via the Pip-Boy. To attach a weapon mod one must have both the weapon it is intended for and the mod in their inventory. Highlight the weapon within the "weapons" section of the Pip-Boy, then select the modding menu via the button as indicated in the top right of the info panel. After selecting a mod, the weapon name will have a + after it to show it has been improved, e.g. Varmint Rifle+. Once a weapon mod has been installed it cannot be removed. Weapon mods that have not yet been attached to a weapon will appear in the "misc" items section of the Pip-Boy.

Achievements/Trophies
Attaching 20 mods to weapons grants the Mod Master achievement/trophy.
Notes
- Weapon mods have a weight of "0.00" listed in their stats where most weightless items have no number displayed at all, none add weight to any weapon, but some mods do reduce the overall weight of the weapon they are equipped on.
- Gun Runners' Arsenal adds 40 weapon mods to weapons in the base game.
- If a weapon has a GRA counterpart, GRA mods can only be applied to the GRA counterpart and not to the base weapon. If the weapon in question does not have an available GRA counterpart, GRA acquired mods can be applied normally.
- If given to a companion or other NPC, a modded weapon's appearance will revert to the weapon's world model, but the mods will otherwise still work. (Example: If you give a silenced 12.7mm SMG to a companion it will appear as if the silencer is missing, however, the weapon will still be silenced.) The "+" addition to the weapon's name can also disappear until taken back.
- Boosts to fire rate from weapon mods are actually calculated squared. A modifier of 30% (1.3x) is in actuality 30%x30% (1.3^2 = 1.69), or 69%.
Behind the scenes
- In the Making of Fallout: New Vegas documentary, Joshua Sawyer stated that during development the team considered making the use of workbenches and Skill checks a requirement to be able to apply modifications to weapons, but ultimately decided against it.[Dev 1]
- Weapon Mod Kits. On console, the file path of the assets for dropped weapon mods is weapons/wmkweapons/modkits, a file path lifted from the popular Fallout 3 mod,
