Trijicon Dual Defense M17/M18 FDE — RMR & Height Sights

Description

The Trijicon Dual Defense Kit combines a compact RMR-style reflex sight with Trijicon’s Suppressor/Optic Height Sight Set into one integrated mounting solution for commercial-variant M17/M18 pistols. The height sights are engineered to sit at the optimal elevation so the iron sight is visible through the optic lens, allowing a true co-witness. This configuration supports rapid target acquisition with the red dot while retaining a mechanical backup aiming option.
