Best Starfield weapon mods

What are the best Starfield weapon mods? These gun attachments can upgrade, boost, and completely change your favorite weapon or adapt your gun to fit your playstyle. Here’s everything you need to know about the types of weapon attachments in Starfield.

We’ve been playing with all the Starfield guns we can get our hands on, and while the base arsenal is entertaining, the real fun comes with customizing your own weapons. You can even give these customized beasts to your Starfield companions to defend themselves against the Starfield Crimson Fleet and all the weird and wonderful beasts the galaxy contains. The best Starfield weapon mods can only be unlocked by completing Starfield research projects – and that’s only the beginning. You also need to collect the necessary Starfield materials in order to craft them.
