To upgrade weapons in Destiny 2, players will need to open up their inventories and right-click a weapon they wish to upgrade. 

After right-clicking a weapon, players will need to hold their cursor over the infusion button, as shown below. Holding the cursor over the infuse button, we make a list of infusible items appear.

Select one of the items and then click infuse. Infusing a weapon will then upgrade a weapon by increasing its power level based on the weapon used to infuse and upgrade. Upgrading weapons will also increase the player’s gear score by a few points.

But to upgrade a weapon, players will need to gather what are called upgrade modules. Upgrade modules are a resource required for infusion, and you can get upgrade modules from Banshee-44 at the tower.

To get upgrade modules from Banshee-44, players must complete one of the various bounties Bashee-44 offers at the tower. Completing these bounties will reward players with upgrade modules, but bounties are not the only method to get upgrade modules.

Players can also purchase upgrade modules from Banshee-44 for the following.

  • 5k Glimmer25 random materialsOne Enchantment Core10 Legendary shards

Once you get a few upgrade modules through bounties or purchasing them, you will be all ready to upgrade your weapons in Destiny 2.
