Holosun Reflex HE508T-RD Elite Details

About the Reflex series

Reflex is one of the red dot sight series made by Holosun. These compact sights are not closed on both sides like the Tube, Infiniti and Paralow series, which is why they are very compact and lightweight (there are some exceptions to this in the Holosun Reflex series – HS512T is closed from both sides and thus bigger while HS510C is a reflex-type red dot sight of a bigger design).

Because of their size, HS407C, HS507C, and HS508T 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 model family

The 508 is one of the model families in the Reflex series. The first number '5' in its name means that the user can switch between a 2 MOA dot; 2 MOA dot surrounded by a 32 MOA circle or a 32 MOA ring only.

About the product (508T-RD)

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

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

Even though ‘C’ is missing in its name, HE508T-RD features a solar panel on top of the frame that surrounds the lens.

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

The product 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.

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.
