The Freedom Ordnance FX-9 4-inch pistol is a modular 9mm AR-style build that wears an SB Mini brace (Freedom Ordnance part no. FX9P4SBM). A 4-inch barrel paired with a 3-inch faux suppressor keeps the overall length near 20 inches. It runs a blowback action and Glock-type magazines, and accepts mil-spec buffer tubes if you want to change the rear. It is a compact 9mm that fits range bags and training classes.
