Can this mount onto an FNX 45 Tactical? — 1 Answer

The Holosun HE509T X2 Enclosed Reflex Optical Red Dot Sight can be mounted to and FNX-45 Tactical. To do so, you can use the RMR adapter plate included with your FN and mount it to your slide, you can then use the RMR adapter plate included with the 509T to then mount the optic. The downside of this method is that you will be stacking 2 adapter plates and adding additional height to the optic. The other method, in which I would recommend, is to purchase and install the C&H Precision FNX-45 to 509T adapter plate. This plate will mount directly to your slide and allow you to mount the 509T without the need for stacking adapter plates and it includes the correct screws required for installation. Unfortunately, we do not carry that specific plate, but it can be found on the C&H website linked below:
