Equiping Power Shot?

How do you equip power shot after you have speced into it?

Do you mean the Ranger Skill "Power Bullet"? If so, then it automatically activates for 30 seconds when you load a Special Round/Bullet (like "Blight Rounds" or "Jellen Shot") from your subpalette.

@AndrlCh Yes that was very helpful. I don’t understand why it lets you spec into that without having one of those.
