Feat 8
Source Player Core pg. 159
Trigger A suppressed creature within your weapon's first range increment makes a ranged attack or leaves a square during a move action it's using.
You concentrate fire on a specific target operating within your weapon’s threat range. Make a ranged Strike against the triggering creature, ignoring the unwieldy trait of weapons you wield for this Strike. On a critical hit, if the triggering action was a move action, you disrupt that action.
