Apex Tactical, FN 509 Action Enhancement Kit, Curved Trigger

Apex originated the drop-in trigger kit for the FN 509. The patent-pending design of the Action Enhancement Trigger Kit for the FN 509 (with Curved Trigger) makes a huge difference in the trigger pull characteristics and immediately became a must-have for 509 owners. When installed, this kit will:

• Reduce trigger pull weight to approx. 5.5 lbs.
• Reduce trigger pre-travel, over-travel and reset distance
• Deliver a crisp trigger break
• Maintain factory safety values with a center mounted pivoting safety
• Direct drop-in replacement, no fitting required
