The little blue wheel adjusts the hop-up. There should be a little word "hop -->" on the wheel, this indicates the direction you turn the wheel to put more of a back spin on the BB.

The little key adjusts your hop-up inside the barrel when the slide is locked back, just match the grooves on the key with the grooves in the barrel and turn (I forgot which way to adjust hop-up)
