The Trijicon MRO (Miniature Rifle Optic) is a legendary, American-made red dot sight engineered for lightning-fast target acquisition. Combining a massive viewing area, rugged forged aluminum housing, and ambidextrous controls, it is the ultimate duty-grade optic for your carbine, subgun, or home defense rifle. 

  • Unlimited Eye Relief & Huge FOV: The large objective lens and carefully designed housing eliminate the dreaded "tube effect," allowing you to keep both eyes open for maximum situational awareness and rapid target transitions. 
  • Bomb-Proof Durability: Trijicon’s signature forged 7075-T6 aluminum housing is fully sealed and nitrogen-filled to handle the harshest environments, drops, and extreme temperatures without losing zero. 
  • Ambidextrous Controls: The centrally located, easy-to-reach rotary dial lets you adjust brightness on the fly without breaking your grip or taking your eyes off the threat. 
  • All-Day (and Night) Battery Life: Enjoy up to 5 years of continuous runtime on a single CR2032 battery (on a medium setting), so your optic is always ready when you need it. 
  • Versatile Models to Fit Your Style:
    • Standard MRO: A crisp 2 MOA dot with adjustable daytime and night-vision settings.
    • MRO HD: Optimized for magnifiers. It features push-button brightness controls and a switchable reticle (from a 2 MOA dot to a 68-inch circle/dot combo).
