HiViz LiteWave H3 Tritium/Litepipe Night Sight Features The HiViz LiteWave H3 Tritium/Litepipe Night Sight merges a self-illuminating tritium vial with the brand s proven Litepipe fiber optic rod to deliver round the clock visibility from a single front sight. In daylight the Litepipe gathers ambient light to produce a bright green glow that is quick to find as the eye moves to the front sight. After dark the tritium insert takes over and continues to glow without any external light source so the shooter never loses the front sight reference during a low light encounter. The green insert is ringed in white for extra contrast against both target backgrounds and the rest of the sight picture helping the eye index to the same spot every time. Machined from steel for a rugged durable sight built to stand up to daily carry and duty use the LiteWave H3 is sold as a front sight only so an existing rear sight can be retained as is. It is designed to fit Smith and Wesson revolvers that use an interchangeable front sight system making it a straightforward upgrade over a factory sight. The sight height of .250 inches is set to work with the intended revolver platforms without requiring additional fitting. Whether carried for personal defense duty or range use this sight gives a shooter a dependable aiming reference day or night.
