First Shots: HiViz FastDot 3 Sights

Bring your sights on-target with a unique "circle in circle" sight picture.

posted on January 26, 2024

The HiViz FastDot H3 sight set is a new low profile single dot sight system that combines both fiber optic and tritium for 24 hour illumination. It has a unique arrangement of a red front sight and green rear sight to create a “circle in circle” sight picture that is bright, easy to acquire, and fast when you need it most. Instead of a traditional blade centered in a notch, front sight into alignment with the rear, the front red sight disappears behind the rear sight leaving behind a glowing green circle to let the shooter know their sights are aligned properly. The FastDot H3 is a low-profile sight that works with all standard holsters and uses fully encapsulated Tritium for 24/7 illumination.
