The Trijicon Electro Optics Bright & Tough Night Sight Set for AR-15/M16 AR- Platform Orange Rear delivers three-dot iron sights designed to dramatically enhance night-fire accuracy without batteries, offering speed comparable to instinctive shooting while maintaining reliability in low light. Housed in a rugged metal body and cushioned within silicone rubber, these sights employ a shock-resistant design with each lamp capped by a sapphire jewel to ensure even light distribution and protect the lamp from solvents and punctures, while aluminum cylinders and silicone cushions provide extra protection against heavy recoil. The orange lamps are designed for fast target acquisition in dim conditions and come with the CP25F-TOOL installation tool for precise setup. With a five-year warranty on the orange lamps from the date of manufacture, this sight set emphasizes durability and long-term performance for serious shooters. Professional installation is recommended to maximize alignment and accuracy, and the system integrates seamlessly with AR-15 platforms, offering a reliable, battery-free sighting option that enhances night visibility and rapid acquisition without sacrificing ruggedness or flight-path consistency in demanding environments.
