Download Weapon Mod Kits A lot has been made of the added weapon customisation in Fallout 4. Pretty much every gun can be kitted out with different grips, sticks, silencers, sights and firing modes. The feature looks incredible for sure, and easily overshadows its predecessor's fairly rudimentary crafting system. But beef Fallout 3 up with Weapon Mod Kits, and crafting becomes a whole new story. With this mod, workbenches become more like one-man weapons factories, as you can kit your weapons out with scopes, silencers, laser sights, new clips and auto-fire mechanisms. Every weapon in the game can have at least one of these mods, meaning you can pimp them up to look those of the professional-looking chap in the picture above.
