Arrow Trip

You are a master with the bow, capable of tripping opponents from a distance by firing arrows in front of them as they move.

Prerequisite(s): Precise Shot, base attack bonus +6

Benefit: You may make a trip attack with a bow or crossbow, as an immediate action, against any opponent that is moving. Your attack roll is treated as your Strength check for purposes of this maneuver – your opponent’s Dexterity check (Strength checks cannot resist a trip attempt made with this feat) must exceed your attack roll or your opponent is tripped by the arrow attack.

This counts as an attack of opportunity attempt for you.
