EOTech EXPS3-4 Holographic Weapon Sight w/ G45.STS 5x Magnifier Review

First Impressions of EOTech EXPS3-4 Holographic Weapon Sight w/ G45.STS 5x Magnifier

The EOTech EXPS3-4 Holographic Weapon Sight w/ G45.STS 5x Magnifier is a premium optic setup designed for rapid target acquisition and enhanced accuracy at varying ranges. As someone who has spent over a decade immersed in the world of tactical gear, I was eager to see if this combo lived up to the hype surrounding the EOTech name. This optic system promises to deliver unparalleled performance in both close-quarters combat (CQB) scenarios and medium-range engagements, appealing to both professionals and serious enthusiasts.

For years, I’d relied on red dot sights for their speed, but found myself wanting more precision at distances beyond 100 yards. I needed an optic that could quickly transition between close-quarters engagements and provide the ability to accurately engage targets further out. The allure of a holographic sight paired with a magnifier seemed like the perfect solution.

Upon unboxing the EOTech EXPS3-4 and G45.STS magnifier, the first thing I noticed was the robust construction and solid feel of both components. The aluminum housing felt incredibly durable, suggesting it could withstand the rigors of demanding use. The quick-detach lever on the EXPS3-4 was smooth and intuitive, indicating ease of mounting and removal.

I considered other options, including Aimpoint’s red dot sights with magnifiers, but the EOTech’s holographic reticle and larger field of view ultimately swayed my decision. The EOTech reputation for being incredibly fast and intuitive also contributed to my choice.

My initial impression was one of excitement tempered with a healthy dose of skepticism, a common feeling after so many years in the tactical gear space. I was eager to get this setup on the range and see if it lived up to its promise of being the ultimate optic solution for versatility and performance.

Real-World Testing: Putting EOTech EXPS3-4 Holographic Weapon Sight w/ G45.STS 5x Magnifier to the Test

First Use Experience

I first tested the EOTech EXPS3-4 Holographic Weapon Sight w/ G45.STS 5x Magnifier at my local shooting range, under bright daylight conditions. I mounted it on my AR-15 platform, and immediately noticed how quickly I could acquire the target. The large sight picture and clear holographic reticle made target acquisition almost instantaneous.

The EOTech reticle remained crisp and easily visible in the bright sunlight. Adjusting the brightness settings was simple and straightforward, with clearly defined levels. I zeroed the optic at 50 yards, and even with the busy four-dot reticle, achieved accurate groupings within the first few shots.

The G45.STS magnifier worked seamlessly with the EXPS3-4, providing a clear and sharp 5x magnification. Flipping the magnifier to the side with the Switch-To-Side (STS) mount was quick and effortless. I did notice that the eye relief was somewhat limited with the magnifier engaged, requiring a consistent cheek weld for optimal clarity.

Extended Use & Reliability

After several months of consistent use, the EOTech EXPS3-4 Holographic Weapon Sight w/ G45.STS 5x Magnifier has proven to be a reliable and durable optic system. I’ve taken it through various environments, including rainy range days and a dusty training course, and it has consistently performed flawlessly. The waterproof and fogproof design are definitely welcome features.

There are no noticeable signs of wear and tear on either the sight or the magnifier. I regularly clean the lenses with a microfiber cloth and have had no issues with scratches or degradation of the optical coatings. The sight holds zero incredibly well, even after repeated mounting and dismounting.

Compared to other red dot and magnifier combinations I’ve used, the EOTech system stands out for its speed, clarity, and robust build quality. The holographic reticle is simply faster to acquire than a traditional red dot, especially under stress. It has outperformed my expectations in terms of both accuracy and overall usability.
