EoTech EXPS2 Holographic Sight - Black, Green 68 MOA Ring with 1 MOA Dot, CR123 Battery, Side Button

The EoTech EXPS2 holographic sight brings true holographic aiming technology to modern sporting rifles, carbines, and tactical platforms. Unlike reflex sights that project a simple dot, this sight generates a holographically-projected reticle on a 68 MOA ring with a 1 MOA center dot—a pairing engineered for rapid target acquisition at close range and precise aiming at distance. Built for hunters, sport shooters, and professionals who demand both speed and accuracy, the EXPS2 is a battle-tested option that has earned trust in the field.

The sight runs on a single CR123 battery with an impressive 1,000 hours of continuous runtime at the nominal brightness setting, so you're not swapping batteries between trips. Its compact footprint—just 3.8" wide and under 12 ounces—keeps your rifle balanced and handling natural. The body is aircraft-grade aluminum, fully submersible to 10 feet, and rated across a -40°F to 140°F operating window. Brightness adjusts across 20 daylight settings, letting you dial in the reticle intensity for morning fog, bright sun, or overcast conditions. Made in the USA, it comes with a quick-start guide, a protective case, and a CR123 battery ready to go.

The EXPS2 mounts to standard 1" Weaver and MIL-STD-1913 rails via a quick-detach lever that holds zero through removals and reinstalls—no tools required. Windage and elevation adjust in half-MOA increments, giving you fine control to dial in your zero. If you're building an AR, carbine, or short-range hunting rifle and want a proven aiming solution that handles both tactical speed and precision, the EXPS2 is worth your consideration.

Frequently Asked Questions

What's included in the box with the EXPS2?

The sight ships with a CR123 battery, quick-start guide, warranty card, protective case, and access to the operator's manual PDF.

Is the EXPS2 compatible with my AR-15 or carbine?

Yes, as long as your rifle has a 1" Weaver or MIL-STD-1913 rail (the standard on most modern AR platforms and tactical carbines). The quick-detach lever makes mounting tool-free.

How long does the battery last?

The CR123 battery provides 1,000 continuous hours of runtime at the nominal brightness setting 12 under room-temperature conditions—roughly 6 weeks of 24/7 use, or many months of typical field use.

Will the sight hold zero if I remove and reinstall it?

Yes. The quick-detach lever is designed to retain zero through removals and reinstalls, so you can swap the sight between firearms or take it off for transport without losing your zero.
