Features Comparison of Holosun 407k Vs Holosun EPS Carry

1. Optical Quality

Holosun 407k

During my field tests, the Holosun 407k X2’s optical quality impressed me with its Red Super LED that offers a crisp 6 MOA dot, enhancing target acquisition. 

The 12 reticle intensity settings allow for clear visibility in various lighting conditions, and the multilayer reflective glass ensures light transmission is top-notch. 

However, I noted a parallax issue at close range, which slightly marred the otherwise stellar performance. Compared to the red dot I’m reviewing alongside, the clarity and brightness are commendable, but this flaw is worth mentioning.

Holosun EPS Carry

The Holosun EPS Carry’s aspheric lens provides a clear sight picture, making it a strong contender. The ability to seamlessly switch between a 2 MOA dot and a 32 MOA circle adds versatility.

During my tests, I appreciated the enclosed emitter design, especially under adverse weather conditions, protecting the reticle from external elements. 

However, the reticle distortion at the lens edge was a notable drawback, impacting precision in critical moments.


The Holosun 407k X2 edges out slightly in this feature due to its superior clarity and brightness across more scenarios, despite the parallax issue at close ranges.

2. Durability and Build Quality

Holosun 407k

The 7075 Aluminum housing of the Holosun 407k X2 stands as a testament to its robustness. In my field tests, it proved resilient against bumps and drops, showcasing Holosun’s commitment to durability. 

The side-mounted battery tray is a practical addition, facilitating easy battery changes. It’s a rugged piece of equipment that instills confidence in its reliability over prolonged use. Compared to its counterpart, its build quality is exceptional, without significantly adding to the weight or bulk.

Holosun EPS Carry

The durability of the Holosun EPS Carry, with its CNC-machined 7075 T6 aluminum, is remarkable. My testing involved several drop tests and rough handling scenarios, to which the EPS Carry responded without a hitch, maintaining zero throughout.

Its robust construction is designed to withstand real-world challenges, making it a solid choice for everyday carry. The enclosed emitter design also adds a layer of protection not seen in all optics.


It’s a close call, but the Holosun EPS Carry takes the win for its enclosed emitter design, adding an extra layer of durability and protection that’s invaluable for everyday carry and use in various conditions.

3. Battery Life and Power Management

Holosun 407k

The 50,000-hour battery life claimed by the Holosun 407k X2 is a significant feature, promising extended use without the need for frequent battery changes. 

My testing confirmed the sight’s efficient power management, though the Shake Awake feature does slightly reduce battery life when activated. 

This technology is innovative, but the practical benefits in terms of power saving were not as pronounced as expected. Compared to the other red dot, it offers substantial battery life, but with a caveat regarding the Shake Awake function.

Holosun EPS Carry

The EPS Carry also boasts an impressive battery life, supported by its Solar Failsafe feature, which I found to be a game-changer during my tests. 

This addition provides an extra layer of reliability, ensuring the sight remains operational even when the battery starts to wane. 

The ability to harness solar power effectively extends the battery life beyond the standard expectations, making it a standout feature in power management.


The Holosun EPS Carry wins in this category, thanks to its innovative Solar Failsafe feature that adds a level of redundancy and efficiency in power management not matched by the 407k X2.

4. Environmental Resistance

Holosun 407k

The Holosun 407k X2’s resilience in various environmental conditions is noteworthy. Its waterproof rating ensures it remains operational even in wet conditions, a crucial aspect of outdoor shooting and tactical situations. 

During my testing, it withstood heavy rain and maintained functionality without any fogging or water intrusion. This level of protection is reassuring for shooters who frequently find themselves in unpredictable weather. 

Holosun EPS Carry

The EPS Carry steps up the game with its enclosed emitter, providing superior protection against dust, water, and debris. 

This design choice is particularly beneficial for maintaining a clear reticle view in adverse weather conditions. 

In my field tests, the EPS Carry excelled in resisting environmental elements, offering uninterrupted performance through dust storms and mud. Its waterproof and shockproof capabilities are on par with the best in the market, ensuring reliability in the most demanding conditions.


The Holosun EPS Carry wins in environmental resistance, thanks to its enclosed emitter design that offers comprehensive protection against all elements, ensuring consistent performance no matter the conditions.

5. Mounting and Compatibility
