The Sightmark® Night Raider 2.5x50 Night Vision Riflescope is a universal night optic designed for short- to medium-range nighttime hunting and observation. The Night Raider is a passive starlight device, which means it does not require an artificial or infrared light source to operate. However, the built-in IR illuminator substantially enhances viewing capabilities, especially in Environments of absolute darkness. Adding to its superior functionality, the Night Raider 2.5x50 Night Vision Riflescope yields a stabilized power supply that resists heavy recoil and ensures uninterrupted operation while shooting. Included is a durable, protective flip-up objective lens cover and remote control. Protected by a three-year warranty on the tube and Sightmark's Limited Lifetime Warranty on the housing, the Night Raider 2.5x50 Night Vision Riflescope is engineered to meet the highest requirements and standards of the serious night vision user.
