C&H Precision Plate for FN 509 to Holosun 509T – Direct Mount Optic Adapter

The C&H Precision adapter plate allows you to mount a Holosun 509T enclosed red dot sight directly to your FN 509 pistol. This machined steel plate replaces the factory optic cover plate, providing a secure, low-profile mounting platform that maintains proper sight height and co-witnesses with factory iron sights.

Manufactured from hardened steel with a matte black finish, this plate is designed specifically for the FN 509 optic footprint and the Holosun 509T. Includes mounting screws and is compatible with factory suppressor-height sights. Installation requires removal of the factory cover plate and minor gunsmithing skills—torque screws to manufacturer specifications for proper retention.
