Features a brightness-adjustable 3 MOA red dot that can be illuminated with 11 different brightness settings to meet the demands of ambient lighting conditions. Built-in Weaver rail mount designed for shock-resistant performance when correctly mounted atop an AR-style rifle. Unmagnified optics have multiple layers of Bushnell's Amber-Bright high-contrast coating for enhanced image quality and improved target acquisition in low light. The 1/2 MOA point of impact adjustments and unlimited eye relief further equip the TRS-25 for the speed and accuracy needed from a tactical weapon system.
