Trijicon MRO SD 1x25 2.0 MOA Reflex Sight
The Trijicon MRO SD (Miniature Rifle Optic, Standard Definition) is a sealed 1x25 reflex sight for rifles, carbines, and shotguns. It keeps the durability and footprint of the original MRO and adds an enhanced optical design tuned for pairing with magnifiers and night vision. A large 25mm objective, ambidextrous brightness dial, and a forged, waterproof housing make it a fast, rugged everyday optic. Choose a model above for reticle color, mount height, and finish.
Key Features
- Large 25mm objective, minimal tube effect: A bigger viewing area speeds up both-eyes-open target acquisition and reduces the tunnel feel of smaller optics.
- 2.0 MOA adjustable dot: A crisp aiming point available in red or green depending on model, fine enough for precision and fast enough up close.
- Ambidextrous brightness dial: Eight brightness settings including two night-vision settings, adjustable by either hand without leaving the fire control.
- Superior multi-coated glass: The SD lens is tuned for a clean sight picture and for pairing with magnifiers and night vision devices.
- Duty-grade housing: 7075-T6 forged aluminum, hard anodized, sealed and waterproof to 100 feet.
- Recessed, protected adjusters: 0.5 MOA clicks in recessed turrets that resist knocks and hold zero.
- Five-year battery life: A single CR2032 lithium battery runs about 5 years at a mid setting.
- Co-witness mount included: Ships with an absolute or lower 1/3 co-witness mount depending on the model you choose.
Featured Highlights

Faster Target Acquisition
A large 25mm viewing area with minimal tube effect lets you find the dot fast and stay on target with both eyes open.

Superior Quality Glass
Multi-coated SD lenses give a clean, true sight picture and are tuned to pair cleanly with magnifiers and night vision.

Long-Lasting Power
A single CR2032 runs roughly 5 years at a mid setting, and the ambidextrous dial keeps brightness a fingertip away.

Built to Handle the Worst
A forged 7075-T6 housing sealed and waterproof to 100 feet shrugs off recoil, drops, and weather.
Description
The MRO's large objective and low-profile housing give a wide, forgiving field of view that makes the dot easy to find and keeps both eyes on the threat. The ambidextrous brightness dial sits within a fingertip of your firing grip, with eight settings including two night-vision settings so the dot is right for anything from a bright range day to working under NODs.
Forged from 7075-T6 aluminum, hard anodized, and sealed and waterproof to 100 feet, the MRO SD holds zero through recoil, drops, and weather. It ships with a Trijicon co-witness mount, either absolute or lower 1/3 depending on the model, so it is ready to run on your flat-top the day it arrives.
Tested to Survive
Every Trijicon optic earns its reputation the hard way, through a battery of punishing tests inspired by real-world use from Alaska to Africa.
