The EoTech EXPS3 holosight is a professional-grade holographic red dot sight built for shooters who need speed, precision, and reliability in demanding conditions. Whether you're running a carbine for home defense, competing in tactical matches, or working a duty rifle, the EXPS3 delivers true two-eyes-open shooting that keeps both eyes open for maximum situational awareness and target acquisition. Its 68 MOA ring paired with a 1 MOA center dot gives you the flexibility to engage targets from close quarters to distance, with a reticle that stays crystal clear across the entire sight picture—no parallax distortion, no fuzzy edges.

Built in the USA and trusted by military and law enforcement professionals, the EXPS3 is engineered for durability that matches the rigors of real-world use. It's waterproof to 33 feet, fogproof, and shockproof, with an operating range from -40°F to 140°F so it performs whether you're training in desert heat or winter cold. The 7mm raised quick-detach base puts your sight at lower-1/3 co-witness height, allowing you to run backup iron sights without obstruction. CR123 battery power delivers 1,000 continuous hours at nominal brightness, and the side-button control panel lets you dial in any of 20 daylight settings or 10 night vision settings without fumbling or breaking your grip.

Night vision compatible and lightweight at 11.2 ounces, the EXPS3 mounts directly to any Weaver or MIL-STD-1913 rail. The quick-detach lever keeps zero when you remove and reinstall the sight, and fine windage and elevation adjustments run 0.5 MOA per click for precision zeroing. Every unit ships with a CR123 battery, quick-start guide, and warranty card—everything you need to mount up and get to work.

Frequently Asked Questions

Is the EXPS3 compatible with night vision?

Yes. The EXPS3 is night vision compatible and includes 10 dedicated brightness settings tuned for Gen I through Gen III+ night vision devices, making it ideal for operations where NV is in play.

Can I co-witness backup iron sights with the EXPS3?

Yes. The 7mm raised quick-detach base positions the optic at lower-1/3 co-witness height, so your iron sights will be visible and usable without the optic blocking your view through them.

What's included in the box?

Each EXPS3 comes with a CR123 battery, quick-start guide, and warranty card. You'll need a Weaver or MIL-STD-1913 rail and quick-detach lever to mount it.

How long does the battery last?

At the nominal brightness setting and room temperature, the CR123 battery delivers approximately 1,000 continuous hours of operation.

Can I remove the sight and remount it without losing zero?

Yes. The quick-detach lever allows you to safely remove and reinstall the sight while maintaining zero, provided you use the same mounting point on your rail.
