Holosun HS508T-RD X2 Open Reflex Pistol Optic

Description

The Holosun HS508T-RD X2 is the premium, duty-grade open-emitter optic in Holosun’s lineup. Built with a rugged titanium housing, a crisp red Multi-Reticle System, and Holosun’s proven X2 electronics, the 508T is the optic trusted by concealed carriers and professionals who want maximum durability without jumping to a fully enclosed design.

If you want the toughest open-reflex red dot Holosun makes, this is it.

Titanium Housing – Built to Survive Real-World Abuse

The 508T isn’t aluminum. It isn’t polymer.
Holosun machined this optic from titanium, giving it:

• Superior impact resistance

• Higher structural rigidity

• Excellent resistance to sweat, moisture, and environmental stress

This is a red dot that can handle the realities of daily carry—hard holster contact, barricade use, vehicle environments, training classes, and weather.

Multi-Reticle System (MRS) – Three Reticles, One Optic

Switch easily between:

• 2 MOA dot

• 32 MOA circle

• Circle-dot combo

The MRS lets you optimize for speed up close, precision at distance, or both. It’s one optic that adapts to how you train and fight.

X2 Series Controls – Fight-Ready Design

The X2 series brings meaningful improvements for concealed carriers:

• Lock Mode prevents accidental brightness changes

• Refined, lower-profile controls

• Shake Awake powers the optic the moment you draw

These refinements matter when the gun sits inside a holster all day.

Solar Failsafe + 50,000-Hour Battery

Holosun’s dual-power redundancy keeps your reticle alive when it counts:

• Solar Failsafe maintains reticle power in bright light—even with a dead battery

• CR1632 battery delivers up to 50,000 hours

• Auto & manual brightness modes for full control

This isn’t just convenience. It’s peace of mind.

RMR Footprint – Maximum Slide Compatibility

The 508T uses the industry-standard Trijicon RMR footprint, making it compatible with most optics-ready duty pistols and aftermarket milling options.

Whether you’re running a Glock MOS, M&P 2.0, Shadow Systems, Staccato, or custom-cut slide, the 508T-RD X2 is ready.
