Description
A sealed 1x25 miniature reflex sight with a 2.0 MOA green dot, built for rifles, carbines and shotguns that need fast target acquisition.
The Trijicon MRO SD is a sealed, miniature reflex sight for rifles, carbines and shotguns, giving fast target acquisition. It keeps the durability and footprint of the original MRO while adding an optical design that pairs well with magnifiers and night vision devices.
A re-engineered objective lens with advanced lens coatings delivers a refined, crisp 2.0 MOA centre dot, optimised for seamless use with the optional MRO 3x magnifier. Upgraded windage and elevation adjusters improve zero retention under direct impact and heavy recoil, and the sight uses a fully sealed, waterproof, hard-anodised forged 7075-T6 housing with ambidextrous brightness controls.
Key features
- Ambidextrous brightness control — The brightness dial works equally well for left- and right-handed shooters, without needing to break the firing grip.
- Eight brightness settings — Eight brightness settings are available, including two compatible with night vision devices.
- Recessed capless adjusters — Sub-flush, capless windage and elevation adjusters prevent lost caps, snag hazards and inadvertent changes to zero.
- Magnifier-ready optics — The re-engineered objective lens and multi-coated glass give a clear, distortion-free dot and are optimised for use with the optional MRO 3x magnifier.
- Rugged sealed housing — The forged 7075-T6 aluminium housing is fully sealed with dry nitrogen and waterproof to 100 ft. (30m).
- Reinforced zero retention — Upgraded windage and elevation adjusters are designed to hold zero under direct impact and heavy recoil.
- Long battery life — A single CR2032 battery powers the LED dot for up to 3 years of continuous use at day setting 3 (setting 5 of 8).
Typical applications
- Patrol carbines and duty rifles that need a fast, both-eyes-open aiming solution.
- Home-defence and tactical shotguns where quick target transitions matter.
- Rifle setups paired with a magnifier or night vision device for extended engagement.
