Been wondering the same question myself today. Ive even been flamed as being a retard for asking to need on gear with aim on it for my companion. Tbh it doesnt make any sence but thnx for making this topic, atleast i can sleep good 2night.
- Opon your character screen (Default C or on the midle-top left of ur screen)
- Click on the tab companion (buttom left corner).
- Drag your gear into the slots .
Enjoy.
Edit: nvm, think i misunderstood ur question.
