HiViz N2 Co-Witness Tritium Features The HiViz N2 Co-Witness Sight Set is machined from steel for durability and finished with Green tritium inserts in both the front and rear sights ensuring visibility in low light or complete darkness. The front sight adds a white ring outline around the tritium vial which improves contrast and speeds up sight acquisition in bright daylight conditions. Set to a 0.430 inch sight height above the slide the sights are engineered to co-witness at or below the reticle of most reflex optics mounted in the Glock MOS cut. This precise height calibration means the irons serve as a reliable backup if the red dot optic fails or runs out of battery. Designed specifically to mount via dovetail on Glock MOS pistols chambered in 9mm .40 S&W and .357 Sig this sight set excludes the G42 G43 G43X and G48 models so fitment should be confirmed before purchase. The combination of a tritium front and rear sight gives shooters 24-hour visibility a critical feature for a defensive or duty pistol that may be used in varying light conditions. Both the front and rear sight are included in the set so no additional parts are needed to complete the co-witness setup. For Glock MOS owners running a red dot sight the HiViz N2 Co-Witness Sight Set offers a dependable purpose-built backup sighting solution.
