Frequently Asked Questions
Will this plate work with the standard FN 509, or only the Optic Ready version?
This adapter plate is designed specifically for the FN 509 Optic Ready model, which comes from the factory with a pre-milled slide cutout and threaded mounting holes. The standard FN 509 does not have this cutout and would require slide milling before this plate could be installed.
Does this adapter plate require any gunsmithing to install?
No gunsmithing is required. The C&H Precision adapter plate is a direct drop-in replacement for the factory cover plate on the FN 509 Optic Ready slide. It installs using the included stainless steel hardware and standard tools, making it a straightforward DIY upgrade for most shooters.
Will my optic maintain its zero if I remove and reinstall the plate?
C&H Precision machines each plate to tight CNC tolerances specifically to support return-to-zero performance. When reinstalled carefully using proper torque on the mounting hardware, the plate and optic should return to zero reliably — though confirming zero at the range after any reinstallation is always recommended best practice.
