Holosun 508t the HE508T-RD X2 is a titanium, open reflex optical sight designed for pistol applications. The X2 Series pistol optics feature two improvements. First is the addition of Lock Mode from our 2018-2019 LE pistol optic models. Lock Mode, when activated, locks the buttons preventing inadvertent setting changes.
Second, the buttons have been redesigned to compliment the Lock Mode by placing them lower and out of the way. Additional features include a Titainium housing, Holosun’s Super LED with up to 50k hours battery life, Solar Failsafe, Multi-Reticle System, and Shake Awake.
Since Holosun’s inception in 2013, our main goal has always been to bring cutting edge technology to the end user. We continuously strive to improve and innovate our products by producing technology that makes sense and works! Below you will find more information on the technology that has made Holosun stand out from the crowd…

Holosun’s Solar Failsafe Technology is an innovative feature pioneered by Holosun in red dot sights.
Solar Failsafe allows the red dot sight to remain powered when your battery fails.
Holosun optics with Solar Failsafe feature automatic brightness adjustment; when you’re under the sun you have a bright reticle, when you move indoors it will automatically dim down to match ambient lighting conditions.

The amount of time it takes for the LED to deactivate (enter Sleep Mode) is user programmable. Shake Awake can also be completely deactivated which keeps the optic powered on for up to 100k hours (certain models).

The 507K is suitable for pistols while its bigger counterpart, the 508T works best on rifles. That being said, you could still mount either one onto your pistol if desired. The 507K sight is the ideal size for pistols, with a smaller window (22 millimeters by 15 millimeters) than its bigger counterpart, the 508T.
What distinguishes HOLOSUN® from other sights?
There are various aspects that distinguish HOLOSUN® from other providers and other technologies. Quite simply: the technology and the price. With the reflex sight technology, the sight does not emit an active light beam, which is why the reticle cannot be perceived by the target. There is no enlargement, but there is parallax freedom. And that enables aiming with two eyes open. In addition, HOLOSUN® is characterized by the interchangeable reticle of most of out models: Here you can switch between dot or circle or circle dot reticle. With these features, we offer hunters, competition shooters and MIL/LE units sights at an unbeatable price.
