Who Should Get EOTECH 518

The EOTECH 518 is tailor-made for shooters who demand precision and reliability.

Whether you’re a competitive shooter, a law enforcement officer, or a hunting enthusiast, this sight offers the versatility and performance to elevate your shooting experience.

Features of EOTECH 518

1. Holographic Reticle (68MOA ring & 1 MOA dot)

The EOTECH 518’s holographic reticle, featuring a 68MOA ring and a 1 MOA dot, is a standout feature that sets it apart in the world of precision optics. This design is ingeniously crafted to provide rapid target acquisition while maintaining a high level of accuracy. 

The larger ring aids in quickly locating the target, especially in high-stress or fast-moving situations. In contrast, the 1 MOA dot at the center allows for precise aiming, crucial for long-distance shots or when precision is paramount. 

This combination of a broad ring and a fine dot caters to a variety of shooting scenarios, offering versatility that is hard to find in other sights.

My Testing 

During my testing, the reticle proved to be exceptionally effective. I found the large ring invaluable for quick target engagement at close ranges. It was especially beneficial in simulated tactical scenarios where speed was crucial. 

For longer-range shots, the 1 MOA dot allowed for pinpoint accuracy. The clarity and brightness of the reticle were consistent across different lighting conditions, a testament to its superior design. 

The only downside I noted was its performance in extremely low-light environments, as this model lacks night vision compatibility.

2. Quick Detach Mount and Compatibility

The quick detach (QD) mount of the EOTECH 518 is a feature that underscores its user-friendly design. Compatible with 1″ Weaver and MIL-STD 1913 Rails, this mounting system allows for swift and effortless attachment or removal of the sight from the firearm. 

This flexibility is crucial for shooters who need to rapidly switch between different platforms or for those who require ease of transport and storage. The mount’s robustness ensures that once attached, the sight remains securely in place, maintaining zero even after repeated recoil.

My Testing 

In my experience, the QD mount performed flawlessly. I tested it on various firearms, including AR-15 platforms and tactical shotguns, and the sight attached seamlessly to each. 

The mount held its zero impressively, even after multiple attachments and detachments and after firing numerous rounds. The ease of switching the sight between different firearms without needing tools was a significant advantage. 

3. Power Source and Battery Life

The EOTECH 518 is powered by two 1.5 V AA batteries, with the option to use CR123, alkaline, or rechargeable batteries. This choice of a common battery type is a practical aspect, as AA batteries are readily available. 

The sight offers impressive battery life, with up to 2,500 hours of continuous use with lithium batteries and 2,200 hours with alkaline batteries at nominal settings. 

This extended battery life is crucial for prolonged use in the field, reducing the need for frequent battery replacements.

My Testing 

During my testing period, the battery life lived up to its claims. I primarily used lithium batteries and found that even with regular use, the battery depletion was minimal. The versatility in battery type choice was convenient, as I could easily switch to readily available alkaline batteries when needed. 

A drawback I noticed was that under constant high-brightness settings, the battery drain was notably quicker. Users should be mindful of this, especially in situations where extended use at high brightness is required.

4. Adjustable Brightness Settings

The EOTECH 518 is equipped with 20 adjustable brightness settings, a feature that significantly enhances its versatility across various lighting conditions. This range of settings allows the user to customize the reticle’s brightness to suit the environment, from the dimmest indoor settings to the brightest outdoor conditions. 

The adaptability ensures that the reticle is neither too dim to see nor too bright to obscure the target. This flexibility is crucial for shooters who find themselves transitioning between different lighting scenarios, ensuring optimal visibility of the reticle at all times.

My Testing 

My experience with the adjustable brightness was highly positive. The range of settings allowed me to fine-tune the reticle’s brightness to match the ambient light, whether indoors or under the bright sun. 

The transitions between settings were smooth, and the sight retained its last setting even after being powered off and on. One minor downside I noticed was that in extremely bright conditions, the highest settings were necessary, which could potentially lead to quicker battery drainage.

5. Water Resistance and Durability

The EOTECH 518 boasts impressive water resistance, being submersible up to 10 feet. This feature is crucial for use in adverse weather conditions and wet environments. Additionally, its overall build quality and durability make it well-suited for rugged use. 

The sight is engineered to withstand the recoil of high-caliber firearms and the general wear and tear of regular field use. This robust construction ensures that the sight remains reliable and functional in various challenging conditions, making it a trusted tool for serious shooters.

My Testing 

I tested the water resistance and durability in various conditions, including rain and submersion in water. The sight performed exceptionally well, maintaining functionality without any signs of fogging or water ingress. The structural integrity remained uncompromised even after rough handling and exposure to recoil. 

However, it is worth noting that while the sight is tough, it is not indestructible. Extreme impacts or conditions beyond its specified limits could potentially compromise its functionality.

Footprint and Mounting Considerations

The EOTECH 518 Holographic Weapon Sight offers a practical balance between size and functionality, designed to fit a variety of firearms without being overly cumbersome. Its dimensions (5.6” x 2.2” x 2.9”) ensure that it doesn’t dominate the rail space, allowing for the addition of other accessories. 

The quick-detach lever is a thoughtful inclusion, making it adaptable to both 1″ Weaver and MIL-STD 1913 rails. This versatility in mounting is essential for shooters who use multiple platforms. However, the lateral placement of the AA batteries slightly increases the sight’s width, which could be a consideration for those with limited rail space or who prefer a more streamlined setup.
