Meprolight USA MPO PRO-F Matte Black Aluminum Mounting Plate - FN 509

The Meprolight USA MPO PRO-F Direct Mount Plate is the factory adapter that lets you bolt the Meprolight MPO PRO-F enclosed-emitter pistol reflex optic directly onto an FN 509 slide, providing a solid, low-profile, direct slide-to-optic connection.

The plate is CNC machined from 6061-T6 aluminum and finished in a non-reflective matte black Type II hard anodized coating that matches the FN 509 slide profile for a clean, factory-style fit. Cut specifically for the FN 509 pistol platform, it ships with the mode-specific screws required to secure the MPO PRO-F to the slide, so installation is straightforward for anyone already running the MPO PRO-F on this handgun.
