The EOTech EXPS3-0 is a holographic weapon sight built for shooters who demand speed and accuracy in tactical, hunting, and professional contexts. Unlike traditional red dot sights, this holographic system projects a true 1 MOA dot reticle onto a reflective window, letting you keep both eyes open and maintain full situational awareness while acquiring targets fast. If you're running a duty rifle, patrol carbine, or hunting setup where quick target transitions matter, the EXPS3-0 delivers the two-eyes-open performance that separates modern optics from older technology.

The sight mounts securely to any 1" Weaver or MIL-STD-1913 rail and sits on a 7mm raised quick-detach base—high enough for true lower third co-witness with iron sights, so you're never without backup aiming. The 20 daylight brightness settings handle everything from dim woods to bright sun, and a dedicated 10 additional settings unlock full compatibility with Gen I through III+ night vision devices. That night vision capacity is a game-changer for military, law enforcement, and serious night hunters who need gear that works across the spectrum.

Built tough for field use, the EXPS3-0 is water resistant to 33 feet and rated to operate from –40°F to 140°F, so weather and temperature swings won't compromise your zero. A single CR123 battery powers the unit for 1,000 continuous hours at nominal brightness, giving you months of reliable performance between changes. Made in the USA, it ships with the sight, a protective case, quick-start guide, warranty card, and a CR123 battery ready to go.

Frequently Asked Questions

Is the EOTech EXPS3-0 night vision compatible?

Yes. The sight features 10 dedicated brightness settings optimized for Gen I through Gen III+ night vision devices, making it a solid choice for low-light and nighttime operations alongside traditional daylight use.

Will this sight work with my iron sights?

Absolutely. The 7mm raised quick-detach base positions the EXPS3-0 at lower-third co-witness height, so your backup iron sights remain visible and functional through the holographic window.

What rail systems does this mount to?

The EXPS3-0 attaches to any 1" Weaver or MIL-STD-1913 Picatinny rail, covering standard AR platforms, rifles, shotguns, and carbines with those mounting systems.

How long does the battery last?

A single CR123 battery powers the sight for approximately 1,000 continuous hours at nominal brightness. The package includes one CR123 battery and a protective case, so you can get on the gun immediately.
