Weapon Mod Research in Starfield Explained

To research weapon mods in Starfield, you need to open up a Research Laboratory and select a specific project. Each project will typically require three different resources, such as Iron, Nickel, and Sealant. In order to start researching more complicated projects, though, you need to have skills in the Weapon Engineering tree.

Without any skill points invested into science, we were able to research weapon mods that were incredibly simple, such as the “Barrel Mods 1” project. As you research more projects, new ones become available that call for even more resources. However, the well will eventually run dry if you don’t have skills invested in science.

Crafting mods and researching them are also entirely separate processes, and if you have been to a Weapons Workbench, you have likely already crafted simple mods. On the other hand, you’re bound to get a notification to research more projects before crafting anything meaningful. This is where the science tree comes in.

How to Research Better Weapon Mods in Starfield

You need to have at least one skill point in Weapon Engineering to start researching higher-level weapon mods. This skill has multiple levels like everything else in Starfield, and each tier will also let you craft more advanced mods after the research is completed.

When attempting to research higher-level weapon mods, there will be a “blocked” notification if you don’t have the right skills. Before getting the Weapon Engineering skill for yourself, keep in mind that it’s in the second row of the science tree, so you need to have about four skills invested beforehand.

Here’s a list of the ranks/tiers for the Weapon Engineering skill in Starfield:

What Do Weapon Mods Do in Starfield?

Weapon mods alter certain aspects of your gun, like the magazine, muzzle, laser, optics, and so on. These improve gun performance and can be crafted at a weapon workbench of your choosing. Make sure you have that specific recipe unlocked.

You can modify nine gun parts as of now, which includes:

  • Barrel.
  • Cover.
  • Grip and Stock.
  • Internal.
  • Laser.
  • Magazine and Battery.
  • Muzzle.
  • Optic.
