This item replaces a mil-spec endplate and castle nut, the FX-9 uses a mil-spec endplate and castle nut, so yes it should work.

Yes, but you will need to purchase the BCG extension from Freedom Ordnance. They sell the extension specifically made for the FX9 BCG. The Law Tactical 1/2" modified will not work. Already been down that road.

It will, but you need to make sure you get the 1/2” bolt extension. If not you’ll have to send it back to them to exchange only that part.

It will fit and work with the extension, but since the lower receiver of the FX-9 is a bit shorter than a standard AR15 I was always hitting my thumb on the hinge of the folder and knocked the skin off of the knuckle of my thumb so I removed it.
