HiViz FX-40 Fiber Optic Front Sight for FN FNS-40 and FNX-40
The HiViz FX-40 is an interchangeable fiber optic front sight designed specifically for FN FNS-40 and FNX-40 pistols. Its 0.198-inch blade height provides a factory-height replacement option for use with the factory rear sight. The steel sight body holds interchangeable LitePipes in green, red and white, allowing you to choose a front sight color suited to your preference.
FN FNS-40 and FNX-40 Front Sight Compatibility
The FX-40 fits the FN FNS-40 and FNX-40. It does not fit FN FNP models. This distinction is important because the FNS, FNX and FNP are separate pistol families; do not assume that a sight intended for one family fits another. Confirm the model marking on your pistol before ordering.
0.198-Inch Blade Height and Factory Rear Sight Compatibility
The FX-40 has a 0.198-inch blade height and is designed at factory sight height for use with the factory rear sight. The LitePipe diameter is 0.050 inch. Verify the sight dimensions against your existing front sight and firearm configuration before installation.
Six Interchangeable Green, Red and White LitePipes
The FX-40 includes six interchangeable fiber optic LitePipes in green, red and white. The included LitePipe-changing key allows you to switch the fiber optic insert, and a carrying case is supplied for storage. The replaceable inserts let you change the front sight color without replacing the complete steel sight.
