About the Holosun 508t red dot sight

Holosun 508T is a red dot sight of the Reflex series.

The letter 'T' means that the dot sight is made of titanium, which makes it stronger and more durable. For this reason, 508T is classified as Elite.

Even though ‘C’ is missing in its name, 508Tdot sight features a solar panel on top of the frame that surrounds the lens.

‘GR’ indicates that this red dot sight comes with illumination in green.

The 508t sight features the ShakeAwake function. When left powered on, the device will go from 'active mode' to 'sleep mode' after a while to prevent unnecessary battery drain. Once moved, it will power back on immediately.

About the Holosun Reflex series

Holosun Reflex is one of the red dot sight series made by Holosun. These compact sights are not closed on both sides like the Holosun Tube, Holosun Infiniti and Holosun Paralow series, which is why they are very compact and lightweight (there are some exceptions to this in the Reflex series – Holosun 512T red dot sight is closed from both sides and thus bigger while Holosun 510C is a reflex-type red dot sight of a bigger design).

Because of their size, Holosun 407C, Holosun 507C, and Holosun 508T products are great for mounting on a pistol.

The illumination is powered by a CR2032 battery. The click value for the elevation and windage adjustments is 0.5 MOA. These durable red dot sights feature a single-piece housing made out of aluminum. Altogether, there are 12 illumination intensity levels to choose from, 2 of which are NVD compatible. The battery life is 50.000 hours.

About the Holosun 'Elite' models

The Holosun's Elite Reflex series is distinguished by having at least one of the following features – green illumination, gold illumination, and titanium housing. Offering illumination other in green and gold is a welcome upgrade for shooters who have problems seeing the red colour. Titanium has been gaining in popularity in the red dot sight market because it is strong, light weight and more resistant to corrosion than aluminium.

About the Holosun "508T" family

Excelent red dot. Robust By
I've been using this red dot for 2 years on my carry gun. It's solid, very good reflex sight. Does the job. Holds zero even dropping the pistol. The battery lasts much - really MUCH - more than other brands and the "shake awake" feature is reliable. I highly recommend, good for the price!

PS: Stay tuned about loosen screws, I had to put extra loctite threadlocker (blue 242).

Holosun Reflex HE508T-RD By
Holosun Reflex HE508T-RD, i have the gen 1 508T, this one improves on the first gen by making it possible to change batteries without removing the optic from the mount. The solar and battery combo and the all around quality and sturdiness of the Holosun Reflex HE508T-RD make it a great option for any gun, rifle of even shotgun. Very light height.

Excellent By
Have been running this on a 9mm competition hand gun (ipsc production optics) for approx 2000 rounds now, and it performs flawlessly. Shake awake feature works great, everything great!

Considering getting another one but not sure what to put it on :)

There are more great reviews online, just do a Google search.
