Trijicon HD XR Suppressor Height Night Sight Set for Glock 20, 21, 29 Yellow Rear Front Outline

Introducing the Trijicon HD XR Suppressor Height Night Sight Set. Trijicon Suppressor/Optic Height Sights are three-dot tritium iron sights that allow shooters the ability to line up their sights in both bright and low-light situations. While standard height sights do not provide an aiming solution when using a suppressed firearm; the additional height of suppressor night sights will clear the added height of a suppressor, allowing shooters the ability to line up their sights on target. Additionally, suppressor night sights can be used as back up iron sights with the Trijicon RMR. Tritium lamps are warranted for 12 years from the date of manufacture.
