The Holosun HE508 Titanium Multi-Reticle Red Dot Sight was designed with pistol applications in mind and come packed with features right out of the box. The Multi-Reticle system allows the user to select between a 32 MOA Circle, a 2 MOA Dot, and a 2 MOA Dot inside a 32 MOA Circle. The HE508 utilizes Shake Awake technology, an advanced system that activates the sight when movement is detected and deactivates when stationary. This means the HE508 is always at the ready, with no need to fumble with buttons at the critical moment of drawing your weapon. In addition, it uses the common CR1632 battery that lasts up to 50k hours. Even when the battery dies, the HE508 will continue to function thanks to the Solar Fail Safe system, that doubles as an automatic brightness adjustment system; when in bright conditions the reticle will automatically increase brightness and automatically dim in lower light conditions.

This optic is simply awesome. The titanium housing is very well made with an excellent tough finish. The glass has minimal warping and light tinting unlike it’s trijicon competitor and costs far less than it as well. The solar brightness auto adjustment works perfectly for me and the large 32 moa ring helps me find the dot much faster, if you are considering this model or it’s trijicon counterpart id steer towards this option, the reticle clarity, adjustability and ease of use blow everything out of the water at a crazy good price point, you don’t even have to remove the optic to change the battery due to the forward thinking side door design, in my mind the Holosun optic is leagues ahead of its competitors at a very modest price, there are no downsides

My 508T stopped working suddenly. I've had it for about a month and it won't turn on. Even tried to change out the battery. A little disappointed given I have holosun on all my other hand guns.

The body is strong Lense is not as good as my RMR rm06 type 2 The battery type is not very common and locally it 3$ more than a 2032 The solar isnt like any other holosun solar options, It will not work without a battery and the auto adjust is bad. Always turn auto adjust off and set the brightness to daylight, when you use your flashlight at night it should be about the same. The elevation range is poor, I have this mounted on top of my PA GLX 2.5-10 and I need a spacer for it to clear the top turret. That just makes the elevation range even worse, If I can get the rmr screws out of my roland special its going on top of my SPR.
