The HiViz CKMFD21 FastDot H3 is a low-profile, single-dot sight system designed specifically for all Canik METE series handguns. It combines fiber optic and tritium for 24-hour illumination without requiring batteries. The system features a red front sight and green rear sight.
This sight uses a circle-within-circle design that sets it apart from traditional blade-and-notch configurations. As you align the front sight with the rear sight, the red front sight disappears behind the rear sight, leaving a glowing green circle to confirm positive alignment. This geometry enables fast sight acquisition, easy sight alignment, positive sight feedback, and improved visibility around the sight picture.
The FastDot H3 pairs a tritium/fiber-optic rear sight with a fiber-optic front sight to deliver 24-hour illumination for a bright and visible sight picture. The low-profile design is compatible with standard holsters, making it suitable for duty use, competition, or personal defense. HiViz covers its tritium sights for 12 years against tritium failure resulting in total loss of illumination due to defects in workmanship or material during normal use; the original owner is entitled to replacement of the entire sight pending inspection for misuse.
