Night Fision utilizes an injection molded process and military-grade polymer with durable polymer tritium outlines to give you flexibility and unrivaled daytime visibility. With the exception of the tritium vials, imported from Switzerland, Night Fision products are crafted end-to-end right here in the USA.
This Perfect Dot night sight set is a square front with green tritium and orange outline and a black u-notch rear. It is compatible with S&W M&P/M&P M2.0/SD9 and 40 VE (excluding M&P Shield and CORE models).
