The FX-9 carbine (Freedom Xtreme-9mm Carbine) has a familiar set of operating controls for the avid AR-15 user, it accepts AR-15 stocks and buffer tube assemblies, as well as most free-float AR-15 rail assemblies. The FX-9 is machined from billet material, anodized type III aluminum components, and full hard nitride steel components including the barrel, bolt, ejector, last round hold open, feed ramp, and extractor for extended wear properties and corrosion resistance. The upper and lower receiver are more than 1 shorter than a standard AR-15, making it more compact and lighter. The FX-9 uses standard, double-stack Glock-style 9mm magazines. It is compatible with 9mm-approved 1/2"x 28 tpi muzzle devices/suppressors, and KNS precision AR-15 trigger pins. This model features a 13" free-floating M-Lok rail with a 3" Picatinny rail section, 6-position collapsing stock, rear charging handle, and comes with a 33-round magazine.
