Holosun HE508T-X2 Review

The Holosun HE508T-X2 is one of the most customizable red dot sights for handguns or pistols. I put this red dot sight on my rifle and I love it, so I wanted to try it on my handgun. I was really surprised by the advanced features of the Holosun HE508T-X2 when compared to the other red dot sights I had tried before.

Want to know which feature impressed me most? Read on to find out…


Like the other Holosun Red Dot Sights, this Holosun HE508T-RD also features their patented multi-reticle system such as MOA Dot & 32 MOA Circle. You can use the 32 MOA circle, 2 MOA dot, or use both simultaneously. For reference, the 32 MOA circle diameter at 100 yards is approximately 32″ (81 cm at 100 m).

These multiple reticle options provide versatility and help you focus on the target, as well as decrease target acquisition time. However, this HE508T-RD is not that much faster than the Burris Fastfire. These reticle combinations are very comfortable for those who have astigmatism, and I suggest you use the larger circle reticles. When compared to all, the 2 MOA dot is the simplest one, but personally, I like the Holosun circle dot with 32 MOA rings that deliver the edge for precise and quick target acquisition.

Brightness Settings

An amazing feature that I’ve found in this red dot sight is that it has 12 brightness settings in total. That’s why they opted for an easy and lockable design on the buttons. Adjusting and changing settings can be very difficult.

You can easily adjust these 12 settings, ten of them for daylight shooting and two for when night vision is needed. Daytime settings are bright, clear, and crisp, so you’ll have no problem with reticle fading on a sunny day.

To be honest, I’m sure most people don’t use two night vision settings, but you can easily make them work for you. Compared to other manufacturers’ models, it’s admirable how Holosun includes them at a lower price.


The latest upgrade to the 508T consists of a major design change in the optic’s shape. In the previous model, you could see the sight’s top was rounded, thus making it more prone to cracking when struck straight on the top of the optic.

The 508T-RD V2 now features a square housing design for the X2, making the already rugged optics even more stable. A new design and an optic body crafted from titanium alloy make this optic one of the toughest in its class and ideal for duty use by law enforcement professionals, and perfect for personal protection roles. This toughness and durability have been proven repeatedly with thousands of rounds fired and numerous impacts to the sight through drops and bumps.

The 508T measures 1.78 (in) x 1.15 (in) x 1.15 (in) and weighs just 2 ounces. The form factor, weight, and size make the use of your pistol just as easy as it was before the sight was mounted.

Apart from these, this optic comes with an Ingress Protection Code of IP67. It means you can submerge the optic into water up to 1 meter deep for about 30 minutes. This IP67 rating also ensures that this optic is dust and particle-resistant and acts as a safeguard for the internal components and electronics. You can also find that there are some drain holes on both sides of the optic that allow excess water to drain from the optic’s exterior and provide traction under wet conditions.

Extended Battery Life 

Unlike other red dot optics you can find on the market, the Holosun HE508T-RD_X2 is powered by an excellent LED, high capacity, and lithium coin CR1632 battery. You can get up to 50,000 hours of battery life so that you can use it for your long hunting sessions and trips without any trouble. Unlike other brands’ red dot sights that stubbornly use bottom loading, the HE508T’s batteries are side loaded. Therefore, you can easily and quickly change the batteries without removing the red dot sight from the pistol.

Moreover, the highlighting feature of this red dot sight is its solar panels, which are placed on the top. It helps extend the battery life and ensures that you will be able to use it for an extended period of time.

If the battery is dead, the red dot sight runs on solar energy. It automatically gathers and adjusts its brightness if you are hunting during the day. Additionally, it features the shake awake technology and an auto shutoff function, which are activated when you move it.

I think this is a very impressive feature when compared to other models of sights at the same price point. It can be very frustrating when your batteries die during hunting or shooting sessions, especially for home security.


To activate the Holosun HE508T sight, press and release any button. To turn off the view, press and release the “+” or “-” buttons.

The Shake Awake feature is also turned off when the view is turned off. Considering the Shake Awake feature and battery life, there are few occasions when you need to turn off the view.

Holosun Shake Awake 

The HE508T-X2 contains Holosun’s Awake feature, which is automatically on when you switch on your red dot sight. If there is no movement for 10 minutes, the sight will go into sleep mode. When you move it slightly, the sight will immediately wake and switch on with the last saved settings.

You can adjust the sleep timer settings by pressing and holding the “+” button for about 10 seconds. Press and release the “+” or “-” buttons to select 10 minutes, 1 hour, 12 hours, or Off. The LED will flash to indicate which setting is selected, then press the “+” or “-” buttons to save the settings.

Auto Mode 

By default, the HE508T-RD is in Auto mode when turning on the optic. In Auto mode, the red dot optic uses a dual power system, while reticle brightness is adjusted automatically based on ambient light situations.

If you want to adjust the brightness according to the situation, press and hold the “+” button for up to four seconds and the reticle will flash once.

In manual mode, you can get 12 brightness levels, which default to level 7 when you first change to this mode.

If you want to adjust the brightness, press the “+” or “-” buttons. To confirm that the optic settings are not accidentally modified, Holoson has replaced the sight buttons and added a lock mode.

Sight and Mounting Adjustment 

This HE508T-RD is attached with a low rail mount so that you can mount the sight to a Weaver rail or Picatinny rail. If you are planning to mount this red dot sight on your handgun, then you need an alternate mounting process.

If your pistol doesn’t have a pre-cut slide, you have to buy a new slide with the cut-out. Or you can use the dovetail style mounting system, which requires you to release the rear sight.

Sight Adjustments 

The 508T comes out of the box factory zeroed at approximately 25 yards to give you a head start. Fortunately, it requires minimal adjustment to reach zero.

The windage and elevation adjustments are done in 1 MOA increments with a +-50 MOA range adjustment. The elevation adjustment screw is located on the top rear of the optic, while the windage adjustment screw is on the right side.


Additional Features and Accessories 

Additional features and accessories include batteries, a lens cloth for cleaning, a low Picatinny rail mount for use as a small optic on a shotgun or pistol caliber carbine, and a footprint similar to the Trijicon RMR for mounting on a pistol slide.

The elevation and windage turrets are lowered into the titanium housing and can be installed and replaced with a screwdriver.

The 508T is waterproof, making it able to handle all types of wet and harsh weather conditions.

What is the difference between Holosun 507 and 508?

The Holosun 507 and 508 are both red dot sights designed for handguns. The major difference between the Holosun 507C and 508T is their material.

Can the Holosun Optic Rely on Its Solar Panel Alone?

No, the solar panel is designed to extend the battery life of the red dot sight. This solar panel works when the battery dies, and it is a final way to keep the optic functioning. Relying solely on a small solar panel is not a good idea.
