Description
Holosun HE508T-X2 Red Dot Sight is the open-emitter optic in Holosun's titanium T-series — worth stating plainly, because the 509T sitting alongside it is fully enclosed and this one is not. What you get instead is a Grade 5 titanium housing on the RMR footprint, 1 MOA clicks over ±50 MOA of travel, and the Multi-Reticle System: 2 MOA dot, 32 MOA circle, or circle-dot.
How It Compares
The same optic in green is the HE508T-X2 Green. If you want the emitter sealed in, that is the HE509T-X2. For an aluminium alternative, the HS507C-X2.
Ideal For
- Duty and defensive pistols on RMR-cut slides
- Builds where housing strength counts for more than a sealed emitter
- Shooters who want dot, circle and circle-dot on one sight
- Hard use without added weight

Product FAQs
What is the difference between the HE508T-X2 and the 509T?
The 508T is an open reflex where the emitter is exposed beneath the glass, while the 509T encloses it. If holster lint and rain are your main worry, the 509T is the one to look at.
Why is the HE508T-X2 built from titanium?
Titanium is tougher than aluminium for the same weight, which is why this is the duty-oriented version. The HE508T-X2 uses a Grade 5 titanium housing.
How much adjustment does the HE508T-RD-X2 have?
It has 1 MOA per click with plus or minus 50 MOA of total travel in both windage and elevation.
Will the HE508T-X2 fit my pistol?
The HE508T-X2 uses the Trijicon RMR footprint. It suits duty and defensive pistols on RMR-cut slides.
What reticles does the Holosun HE508T-X2 red dot offer?
The Multi-Reticle System gives a 2 MOA red dot, a 32 MOA circle, or a circle-dot. That is dot, circle and circle-dot on one sight.
What battery does the HE508T-X2 red dot use?
It uses a side-loading CR1632 battery rated for up to 50,000 hours. Solar Failsafe and Shake Awake support it.
Does the HE508T-X2 have solar power backup?
Yes, the HE508T-X2 has Solar Failsafe along with Shake Awake. These pair with the side-loading CR1632 battery.
Is the HE508T-X2 magnified?
No, the HE508T-X2 is 1x, parallax-free with unlimited eye relief. It is a non-magnified open reflex sight.
What glass does the HE508T-X2 use?
The HE508T-X2 uses X2 glass. It sits in a Grade 5 titanium housing on the RMR footprint.
What is in the box with the HE508T-RD-X2?
The box contains the Holosun HE508T-X2 red dot sight, mounting hardware and fitting tool, and a CR1632 battery.
Does the HE508T-X2 come in green?
Yes, the same optic in green is the HE508T-X2 Green. For an aluminium alternative in red, the description points to the HS507C-X2.
