The Trijicon Fiber Optic Suppressor Height Sight Set for M & P C.O.R.E and M & P M2.0 Optics Ready is an elevated, battery-free open iron sight system purposely engineered to co-witness with slide-mounted pistol electronics. Utilizing the advanced light-gathering chemical principles pioneered in Trijicon's legendary ACOG combat optics, the front post concentrates ambient light to deliver an ultra-brilliant daylight focal point. Its tall, suppressor-height profile is explicitly structured to clear the high body profiles of muzzle-attached suppressors or smoothly serve as a reliable backup sight picture if a red dot reticle ever fails. CNC-machined entirely from robust solid steel and treated with a resilient matte finish, the entire assembly effortlessly shrugs off intense slide cycle g-forces and aggressive holster friction. Additionally, the rear sight is shaped with a steep, hard-angled front ledge explicitly designed to enable situational, emergency one-handed slide cocking against a belt or rigid barrier.
