The weapon mods range from scopes and silencers to extended mags and several in-between. 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.īy 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. However, some unique variants have both mods and better base stats. 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. 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 in Fallout 3 this was limited to the creation of custom weapons, New Vegas takes this a step further by allowing the creation of weapon variants based on basic weapons by adding weapon mods. One of the features added to New Vegas is the ability to custom modify certain base weapons. “ Weapon mods can increase ammunition capacity and damage, reduce spread and weight, or add special equipment like scopes. Other differences between unique weapons do not technically count as weapon mods, seeing as there is only one of each unique weapon. The only upgrades seen in Fallout 3 are scopes, the occasional use of silencers and the use of extended magazines.
