The Freedom Ordnance FX-9 4-inch FDE is a 9mm AR-pattern pistol with a 4-inch barrel, built on a pistol receiver extension (brand part no. FX9P4T-FDE). Freedom Ordnance machines the FX-9 in the USA from billet aluminum and pairs it with Glock-type magazines and AR-15 controls for easy familiarity. A 3-inch faux suppressor at the muzzle gives it the look of a suppressed build, and the free-float M-LOK rail accepts accessories. The 4-inch barrel is a good match for close-quarters handling, vehicle storage and a compact home-defense build. This example is finished in Flat Dark Earth, one of the colors Freedom Ordnance offers on the FX-9 line.
