Will this be a direct fit for FN FNX 45 Tactical? Or will it fit with the mounting plates FN provides? Will it be a true co-witness with the suppressor height night sights that come with this weapon?

Question

James G. · Answer

Hi John and welcome. It will fit the FN RMR Mounting Plate supplied. Be sure and use blue loc-tite on the screw threads and let it cure for a few hours before use. Cheers, stay safe and enjoy!
