Description
A sealed miniature reflex sight for rifles, carbines and shotguns, delivering fast target acquisition for professional shooters, supplied with a full co-witness mount.
The MRO SD is a sealed, miniature reflex sight intended for use on rifles, carbines and shotguns, giving fast target acquisition. It keeps the durability and footprint of the original MRO while adding an enhanced optical design that works well with magnifiers and night vision devices.
A re-engineered objective lens with advanced lens coatings produces a refined, crisp 2.0 MOA centre dot optimised for the optional 3x magnifier. Upgraded windage and elevation adjusters improve zero retention under direct impact and heavy recoil, alongside ambidextrous brightness control and a fully sealed, waterproof, hard-anodised forged 7075-T6 housing.
Key features
- Full co-witness mount — This model ships with a full co-witness mount, aligning the dot with the iron sights below it.
- Ambidextrous brightness control — The brightness dial sits within reach of either hand, so it can be adjusted without moving the firing hand off the controls.
- Magnifier-ready optics — A re-engineered objective lens with advanced coatings produces a crisp 2.0 MOA dot optimised for use with the optional 3x magnifier.
- Recessed, capless adjusters — Sub-flush windage and elevation adjusters remove exposed caps, cutting the risk of snagging or losing zero from an accidental knock.
- Sealed, waterproof housing — The forged 7075-T6 aluminium housing is fully sealed and waterproof to 100 ft (30 m), protecting the electronics in the field.
- Long battery life — A single CR2032 battery powers the sight for up to 3 years of continuous use at a typical daytime brightness setting.
- Eight brightness settings — Eight illumination settings, including night-vision-compatible steps, let the dot be matched to daylight or low-light conditions.
Typical applications
- Patrol carbines and duty rifles that need fast, both-eyes-open target acquisition.
- Shotguns used for home and personal defence where a wide field of view speeds up hits.
- Rifle setups paired with a magnifier or night vision device for close-to-mid-range work.
- Working environments where the sight may be exposed to rain, immersion or rough handling.
