Holosun HS507C-X2 Design

The Holosun HS507C-X2 design isn’t different from the brand’s outstanding line of red dot sights. It’s a lightweight red dot sight that’s built for pistol and shotguns applications. The optic is made with aluminum material to enhance its durability and strengthen its resistance to environmental torture.

The dot sight has a waterproof rating/submersion temperature of IP67, which means that the device is usable under light rain conditions.

Additionally, the battery compartment isn’t positioned differently from the other red dot sights produced by Holosun. It sits behind the transparent glass, which doesn’t act as an impediment to the shooter’s focus on his target.

Features of the Holosun HS507C-X2

No Holosun HS507C-X2 review is complete without highlighting its features. The popular red dot sight includes the following features.


The Holosun HS507C-X2 has 1x magnification, making it possible for the shooter to zoom in on his target. Though it doesn’t exceed 1x magnification, our experts were satisfied with the level of enlargement.

Eye Relief

Unlike some optics that tend to inflict some excruciating pain to the eye after usage, this micro-optic provides eye relief during and after use, thanks to the reticle green color. Our team didn’t feel any pain in the eye while testing the red dot optic.

Multiple Reticle System

One of the best features of this optic is its multiple-reticle system. We found it super easy switching between a 32 MOA and 2 MOA during our testing, all at a simple push of a button. The multiple-reticle system allows the user to get more visual information on his target, resulting in better close-up shots.

Holosun HS507C-X2 Solar Failsafe

Thanks to the innovative solar failsafe from Holosun, you have a battery back-up to fall on should the main battery disappoint[1]. We highly commend the brand for including this power back-up option.

Long Battery Life

The Holosun HS507C-X2 is powered by a battery back-up, capable of delivering up to 50,000 hours of battery life. This means the red dot optic can work for hours without running out of juice. And should it fail during your shooting rounds, you have the alternative solar failsafe to fall back on.

Holosun HS507C-X2 Brightness Settings

Adjusting the screen’s brightness is simple. Our team of experts didn’t encounter any issue turning the brightness knob on/off for adjustments. It was a seamless experience — something we know will make shooters happy.

Long Battery Life

Shake Awake technology is one of the best features an optic brand has incorporated into a red dot sight device. Practically, our team was amazed by what this feature could do in such a small device.

While conducting our test, we observed two things Shake Awake technology could do — it turns on the device once movement is detected or turns off due to no movement and recalls the last brightness setting. Turning the device on/off will help prolong the battery life. Remembering the previous brightness setting will save you the time of setting the brightness all over again, which only says one thing — convenience.

Holosun HS507C-X2 Review Conclusion

The Holosun HS507C-X2 is an excellent, high-performing red dot sight that satisfies all requirements. As pointed out by our team of experts in this Holosun HS507C-X2 review, the dot sight packs feature will make short-range shooting seamless and efficient.

With its multiple-reticle system and magnification, you can switch between different MOA and zoom-in expediently for optimal close-up shots. Furthermore, the dual power options are excellent in providing battery life that lasts almost a decade. The inclusion of Shake Awake technology will help even save more battery juice.
