From what information I could find the Foxtrot Mike FM-9 uses a proprietary barrel nut and handguard that lock into a cutout in the top of the upper receiver. Because of this design the Aero Precision AR15 Quantum M-LOK Handguard will probably not work. I recommend contacting Foxtrot Mike in regards to aftermarket handguard compatibility with the FM-9.
