Apex Tactical Specialties Action Enhancement Kit is a direct drop-in trigger kit to upgrade your FN 509. It has a flat trigger shoe and is available in either Black or Flat Dark Earth. The kit includes parts necessary to replace the factory polymer trigger, trigger bar, and sear. The patent pending design reduces trigger pull weight to approximately 5.5 pound range. This upgraded trigger also reduces trigger travel, including pre-travel, over-travel, overall trigger travel and trigger reset distance. Provides a smooth uptake while delivering a crisp trigger break for your factory FN 509.
