Questions & Answers
would this plate work FN 509c? Expert Answer

This C&H Precision Weapons FN 509 Adapter Plate will fit optic ready models of the FN 509, including the 509C. However, if you do not have an optic ready model of the 509C, then you will need to use the Evolution Gun Works Trijicon RMR Sight Mount which can be found linked below:
