Eotech EXPS3-0HD 68RING/1 MOA QR BLK

The Eotech EXPS3-0HD is a hoodless holographic red dot sight built for shooters who demand speed and situational awareness in the same optic. Unlike traditional tube designs, the EXPS3-0HD's open architecture gives you unobstructed peripheral vision while keeping both eyes open for faster target acquisition—ideal for home defense, tactical rifle work, and competitive shooting where reaction time matters. It's a modern take on Eotech's proven holographic platform, refined with smart features that don't get in your way.

The real-world standout here is the left-side rotary brightness dial paired with shake-awake technology, so you're not fumbling with controls in a critical moment. The optic auto-adjusts across 7 daylight settings plus 4 dedicated night-vision modes, and there's a full auto-brightness mode for hunters and outdoorsmen who move between light conditions. Shake-awake means the sight powers down to save battery but wakes instantly when you move the gun—no dead batteries from a forgotten on/off switch. All-aluminum construction keeps weight down at 11.6 oz and delivers the durability Eotech is known for.

Compatibility is built in: it mounts to any Weaver or MIL-STD-1913 rail, and the 1.74-inch centerline height gives you a true lower-third co-witness with standard iron sights. Night-vision compatible, water-resistant to 33 feet, and rated for temperatures from -40°F to 140°F, the EXPS3-0HD handles the conditions where you actually hunt and train. The 68 MOA ring with 1 MOA dot is the classic Eotech reticle—fast for close work, precise enough for distance.

Made in the USA, the EXPS3-0HD runs on a single CR123 battery with an impressive 1000-hour runtime at nominal settings. For rifle shooters who want a no-compromise red dot with magnifier-compatible optics mounting and a proven track record in the field, this is the real deal.

Frequently Asked Questions

Is the EXPS3-0HD compatible with magnifiers?

Yes. The hoodless design and Weaver/MIL-STD-1913 mount platform allow magnifier compatibility. You can pair it with an Eotech or third-party magnifier for extended-range work without obstruction.

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

The EXPS3-0HD runs on a single CR123 battery. At nominal brightness settings and room temperature, you'll get roughly 1000 hours of continuous runtime—roughly 40+ days of continuous operation. Shake-awake technology powers down the sight when dormant, so real-world battery life in tactical or hunting use is significantly longer.

Will the EXPS3-0HD work with night-vision devices?

Yes. The optic is fully night-vision compatible with dedicated brightness modes optimized for all generations of NV tubes. It includes 4 dedicated night-vision settings separate from daylight modes.

What co-witness height does the EXPS3-0HD provide?

The 1.74-inch centerline height gives you a lower-1/3 co-witness with standard iron sights, allowing you to shoot over your backup irons without obstruction or reticle blooming.
