Viridian Mds25 Modern Dot Sight Vir 981-0127 Mds25 Modern Dot Sight 1x29 Grn T2

The Viridian MDS25 Modern Dot Sight is a 1x29 green reflex optic built for shooters who demand speed and clarity in any light. Mounted on the Aimpoint T2 footprint, this compact sight puts a crisp 3 MOA green dot on target—leveraging the human eye's natural sensitivity to green wavelengths, a technology Viridian refined over nearly two decades. Whether you're running a defensive rifle, competition setup, or hunting rig, the MDS25 delivers the parallax-free performance and unlimited eye relief that make rapid target acquisition feel effortless.

Built tough for real use, the MDS25 is machined from 6061 aluminum with hard coat anodization and sealed to IPX6 waterproof and fogproof standards. It'll survive the recoil and impacts of serious shooting without losing zero. Tool-free windage and elevation adjustments mean you can dial in your sight fast—no screwdrivers, no fuss. At 7.8 ounces and just 2 inches long, it sits low and compact on your rail, leaving plenty of room for a magnifier or keeping your sight picture uncluttered.

The CR2032 battery runs the Instant-On activation for over 30,000 hours, so you're not swapping cells every range trip. Temperature range spans -4°F to 130°F, covering everything from early-season hunts to desert runs. With 90 MOA of total adjustment and fully multi-coated glass, the MDS25 is a no-compromise green dot for shooters who don't settle.

Specifications

Frequently Asked Questions

Is the MDS25 compatible with Aimpoint T2 mounts?

Yes. The MDS25 shares the Aimpoint T2 footprint, so it works with any mount designed for that standard—a huge advantage if you already have T2-compatible accessories or plan to swap between optics.

Will this sight work in low light and bright sunlight?

Absolutely. The green reticle is optimized for rapid target acquisition across varying light conditions because the human eye is inherently more sensitive to green wavelengths than red. The fully multi-coated lens and unlimited eye relief also maximize your ability to pick up the dot in any environment.

What battery does it use and how long will it last?

The MDS25 runs on a CR2032 battery. With Instant-On activation, you get over 30,000 hours of battery life—roughly 3.4 years of continuous operation, so you won't be changing batteries constantly between hunting seasons or range days.

Can I adjust windage and elevation without tools?

Yes. The MDS25 features tool-free windage and elevation adjustments, letting you dial in your zero quickly in the field without carrying adjustment tools or fumbling with screwdrivers.
