Trijicon 600689 Suppressor/Optic Height Sights Green/Tritium White Outline Front Sight-Green/Tritium White Outline Rear Sight Glock 20/21 Large Frame

Trijicon Suppressor/Optic Height Sights are three-dot iron sights that increase night-fire shooting accuracy by as much as five times over conventional sights. Equally impressive, they do so with the same speed as instinctive shooting - and without the need for batteries. Housed in a metal body and cushioned within silicone rubber, Trijicon Suppressor/Optic Height Sights feature a unique shock-resistant design. Each lamp is capped with a sapphire jewel to help evenly distribute the light while protecting the lamp from solvents and puncture. Contained within aluminum cylinders for additional protection, the lamps are mounted on silicone rubber cushions to withstand shock and heavy recoil. Green lamps are warranted for 12 years from the date of manufacture. Professional installation recommended. Front Sight Width: 0.144". Front Sight Height: 0.403". Rear Sight Height: 0.451".
