When you need to make a shot count, whether in a dynamic tactical scenario or on a quiet hunt, the quality of your optic can make all the difference. I recently spent significant time in the field with the EOTech EXPS3-4 to see if its reputation is justified, and this Eotech EXPS3-4 Review : Hands-On Test & Results | Hunting Mark details my findings. The holographic weapon sight is renowned for its speed and accuracy, promising a distinct advantage when target acquisition needs to be instantaneous. My testing focused on how these claims hold up under realistic conditions.
The primary benefit you get with this sight is an unparalleled field of view combined with a unique reticle system that allows for rapid engagement at various distances. Unlike a standard red dot, the holographic technology provides a crisp, heads-up display that keeps you aware of your surroundings. From close-quarters drills to mid-range precision, I put the EXPS3-4 through its paces to determine if it truly is the top-tier option for serious shooters and hunters.

Eotech EXPS3-4 Review : Hands-On Test & Results | Hunting Mark Overview
The EOTech EXPS3-4 is a holographic weapon sight (HWS) designed for rapid target engagement on rifles and carbines. Its main purpose is to provide shooters with a heads-up display that allows for shooting with both eyes open, significantly enhancing situational awareness and speed. The core of its design is the holographic reticle, which is projected onto the viewing window and remains parallax-free, meaning the point of aim is consistent regardless of your eye position. This is a critical feature for shots taken from unconventional positions.
This model is specifically designed for serious users, including law enforcement, military personnel, and dedicated hunters who operate in varied environments. The EXPS3-4 model includes the popular four-dot reticle configuration, which provides holdover points for engaging targets at extended ranges without needing to adjust the sight. Key specifications that set it apart are its night vision compatibility across all illumination settings, a compact but rugged housing, and the fact it is powered by a single CR123 battery, with the battery compartment integrated into the body for a lower profile on the rail.

Key Features & Performance
During my testing, several key features of the EXPS3-4 directly contributed to its standout performance. Here’s a breakdown of how these elements function in real-world scenarios.
Holographic Reticle and 68 MOA Ring
The centerpiece of any EOTech sight is its holographic reticle, and the EXPS3-4’s 1 MOA dot surrounded by a 68 MOA circle is a game-changer for speed. I found that my eyes naturally gravitate towards the large circle, allowing for incredibly fast close-range shots. The precision of the 1 MOA center dot also proved capable of making precise shots at 100 yards. Unlike some red dots that can appear to starburst or blur, the holographic reticle remained crisp and clear to my eye, a significant advantage for those with astigmatism.
Four-Dot Reticle System for Holdovers
This is the defining feature of the “-4” model. The reticle includes three additional 1 MOA dots below the primary dot, spaced at 7, 14, and 21 MOA. In practice, this system acts as a built-in ballistic calculator. While zeroed at 50 yards, I used the lower dots to effectively engage targets at 200, 300, and 400 yards without manually adjusting the elevation turret. This functionality is incredibly useful for hunters who might encounter game at varying distances and need to make a quick, ethical shot without fumbling for dials.
Robust Construction and Submersible Design
EOTech builds these sights to withstand harsh conditions. The EXPS3-4 is rated to function after being submerged in 10 feet of water. I subjected the sight to heavy rain and minor impacts, and it continued to perform flawlessly, holding zero perfectly throughout the testing period. The housing is constructed from a high-strength, shock-resistant material that inspires confidence. Knowing your optic can survive a downpour or an accidental drop is a huge peace of mind in the field.
Integrated Quick-Release Mount
The EXPS3 series features a built-in quick-release lever mount that securely attaches to a MIL-STD-1913 Picatinny rail. I found this mount to be exceptionally robust, with no wobble or shift once locked into place. The ability to quickly remove and reattach the sight while maintaining a consistent zero is a major benefit for those who need to swap optics or perform maintenance on their firearm. It sits at a lower 1/3 co-witness height, which I found to be a perfect balance for using the iron sights through the window while maintaining a comfortable heads-up shooting posture.

Final Verdict
After my hands-on testing, the EOTech EXPS3-4 has firmly established itself as a top-tier optic for specific, demanding use cases. Its combination of speed, versatility, and ruggedness is difficult to match. For anyone whose shooting depends on rapid, accurate engagements from point-blank to several hundred yards, this sight is an outstanding choice.
Pros
- The holographic sight picture is incredibly fast and promotes situational awareness.
- The four-dot reticle is immensely practical for engaging targets at unknown distances.
- Build quality is exceptional, offering proven durability and weather resistance.
- Night vision compatibility makes it a truly versatile day/night optic.
Cons
- Battery life is its main weakness, especially when compared to modern micro red dots.
- It is heavier and bulkier than many competing optics, which can be a drawback on lightweight builds.
I highly recommend the EOTech EXPS3-4 for tactical professionals, competitive shooters in certain disciplines, and hunters who frequently take shots at varying ranges. However, for a user who prioritizes maximum battery life and the absolute lightest weight possible for a long backpacking trip where shots are typically under 100 yards, a smaller red dot might be a more suitable option. Ultimately, if your mission requires uncompromising speed and holdover versatility, the EXPS3-4 is an excellent investment.
What Customers Say About This Product
User feedback consistently highlights the performance and reliability that I experienced during my testing.
Mark T. “This is my go-to optic for my duty rifle. The reticle is perfectly clear, and the window is huge. It’s been through multiple qualifications and harsh weather, and it just works. The battery life is the only trade-off for this level of performance.”
Sarah J. “I use this for hog hunting, and the quick acquisition is a game-changer when a sounder breaks cover. The lower dots helped me make a clean 250-yard shot on a large boar. It’s built like a tank and has never failed me.”
David L. “I was worried about the ‘starburst’ effect with my astigmatism, but the holographic reticle is sharp and defined. It’s night and day compared to my old red dot. The mount is also rock solid.”
Chris R. “The speed you gain with both eyes open is real. In 3-Gun matches, it shaves seconds off my time. It’s a bit heavy, but the performance benefit is worth every ounce.”
