The Trijicon MRO® 2.0 MOA is a compact reflex-style red dot sight engineered for quick target acquisition on rifles, carbines, and shotguns. Its large 25 mm objective and optimized lens design deliver a crisp 2.0 MOA center dot with an expansive viewing window for excellent situational awareness. Built from forged 7075-T6 aluminum with advanced lens coatings and protected, sub-flush adjusters, the MRO is sealed, rugged, and designed to hold zero under recoil and rough handling. 

Key features

• Refined 2.0 MOA center dot — clean, precise aiming point ideal for close-to-mid-range engagements.  
• Large 25 mm objective / wide viewing area — larger field of view speeds target acquisition and reduces “tube effect.”  
• Rugged construction — hard-anodized forged 7075-T6 aluminum housing for durability.  
• Ambidextrous brightness control with multiple settings (including NV-compatible levels on select models) for low- and high-light use.  
• Protected, sub-flush windage/elevation adjusters — minimizes accidental movement and snag hazards; no special tools required.  
• Sealed and fogproof (dry nitrogen-filled) and waterproof to military-grade depths.  
• Long battery life — runs on a single CR2032 lithium cell with industry-leading runtime (varies by model/setting).
