The FX-9 pistol (Freedom Xtreme-9mm pistol) has a familiar set of operating controls for the avid AR-15 user. It accepts AR-15 stocks / braces and buffer tube assemblies, as well as most free float AR-15 rail assemblies. The FX-9 comes standard with a 33 round double stack Glock style 9mm magazine. When we designed the FX-9 our goals were reliability, affordability, and familiar controls for the user. The FX-9 is machined from a billet and all aluminum components are type III anondized. Steel components are nitride or nickle boron finished for extended wear properties and corrosion resistance. The upper and lower receiver are shorter than a standard AR-15 making it more compact and lighter than a standard mil-spec AR-15 design.
