The Apex Heavy Duty Striker for the FN 509, FNS and FNS Compact is a direct drop-in replacement option for customers with FN 509 and FNS series pistols. The striker is machined from a billet of stainless steel and heat treated for enhanced durability.

Expected Results
– Direct drop-in replacement of FN 509, FNS, FNS Longslide and FNS Compact striker
– Requires use of the following factory striker components: Striker Spring Stop Pin, Striker Spring Guide, Striker Return Spring, Stop Pin and the Striker Spring.

The Apex Action Enhancement Kit for the FN 509 model pistols is a direct drop-in replacement of the factory polymer trigger, trigger bar and sear. The patent pending Apex design reduces trigger pull weight to give you an approx. pull weight in the 5.5 lbs range. Trigger travel is also reduced, including pre-travel, over-travel, overall trigger travel and trigger reset distance. It provides a smooth uptake while delivering a crisp trigger break.

Expected Results
– Direct drop-in replacement of factory polymer trigger, trigger bar and sear
– Reduces trigger pull weight to approx. the 5.5 lbs. range
– Reduces trigger pre-travel, over-travel and reset distance
– Provides crisp trigger break
– Center mounted pivoting safety maintains factory safety values

FN AR15 barrels are hammer forged using the same proprietary high-grade Chrome Moly Vanadium steel used in FN's venerable machinegun barrels produced to handle the punishment of sustained fully automatic fire. After forging" each barrel is Magnetic Particle tested to ensure that it is free of micro stresses or flaws" resulting in consistency and quality in every barrel shipped from the factory. The bore and chamber are chrome lined to help resist corrosion and provide resistance to heat erosion which greatly improves barrel life and reliable chambering/extraction. The M4 style feed ramps and barrel extension provide consistent feeding and the matte black Manganese Phosphate finish resists external corrosion and oxidation.
