C&H Precision Optic Plate for FNX-45 to Holosun 509T Steel

If you want to mount a Holosun 509T on your FNX-45 Tactical, you need an adapter plate designed for strength, precision, and repeatability. This steel plate is CNC-machined for a direct fit and finished with a durable electro-deposition coating. It installs easily, locks down your optic, and keeps it zeroed under heavy recoil—giving you a rugged solution without the need for slide milling.
