Product DescriptionTrijicon Suppressor/Optic Height Sights are three-dot tritium night sights built to give Glock shooters a clear sight picture in bright light, low light, and no light. This set features a highly visible yellow front outline paired with a black rear outline and green tritium lamps for fast acquisition. The increased height clears most pistol suppressors and provides a dependable co-witness/backup with slide-mounted red dots such as the Trijicon RMR. Lamps are housed in protective aluminum sleeves, cushioned by silicone rubber, and capped with a sapphire jewel for durability and even light distribution. Machined steel construction and a matte black finish complete this rugged setup.Product Highlights Suppressor/optic-height threedot tritium sights for Glock standard-frame models Yellow front outline with black rear; green tritium lamps with 12year warranty Steel bodies with protective aluminum lamp sleeves and silicone rubber cushioning Sapphire-capped tritium lamps for even light and solvent resistance Ideal as backup iron sights when running a slide-mounted red dot optic Specs Compatibility: Glock 17, 17L, 19, 22, 23, 24, 25, 26, 27, 28, 31, 32, 33, 34, 35, 37, 38, 39, 45 Front Outline Color: Yellow; Rear Outline Color: Black Illumination: Green tritium phosphor (batteryfree); green lamps warranted for 12 years Construction: Machined steel with aluminum lamp sleeves and silicone rubber cushioning; matte black finish Front Blade Height: 0.365 in; Rear Blade Height: 0.361 in Overall Height: Front 0.42 in; Rear 0.45 in; Rear Notch Width: 0.15 in Weight: 0.026 lb Country of Manufacture: USA UPC: 719307620612 MPN: GL201-C-601135 Brand: Trijicon Disclaimer: We strive to provide accurate and up-to-date product descriptions, specifications, and images; however, errors or omissions may occasionally occur.
