The Trijicon 600900 Suppressor/Optic Height Sights are three-dot iron sights that dramatically improve night-fire accuracy by as much as five times over conventional sights, delivering fast, instinctive speed without the need for batteries. Housed in a robust metal body and cushioned within silicone rubber, these suppressor/optic height sights feature a shock-resistant design that stands up to heavy recoil, while each lamp is capped with a sapphire jewel to distribute light evenly and protect against solvents and puncture. The green lamps are backed by a twelve-year warranty from the date of manufacture, ensuring dependable performance in varying conditions. Specifically engineered to fit Smith & Wesson M&P and M&P M2.0 platforms, including SD9 VE and SD40 VE models (excluding M&P SHIELD & C.O.R.E. series), they provide precise front and rear alignment with a front sight width of 0.144 inches and front/rear sight heights around 0.445 and 0.444 inches respectively. With a bright green front and green/tritium white outline rear, these suppressor-height sights enhance accuracy in low-light scenarios, making them an excellent choice for defenders, competition shooters, and serious hunters seeking reliable, battery-free illumination.
