Holosun HE509T X2 1x Gold Dot Multi-Reticle Closed Emitter Titanium Reflex Sight

The Holosun HE509T X2 enclosed-emitter reflex sight is purpose-built for full-size, competition, and defensive pistol applications where a rugged, sealed red dot is essential. The housing is machined from Grade 5 Titanium, giving the optic an outstanding strength-to-weight ratio and excellent corrosion resistance while keeping carry weight down. A fully closed emitter design protects the LED from rain, dust, debris, and pocket lint, the same failure points that plague open-emitter reflex sights on carry guns.

The HE509T X2 runs Holosun's signature Multi-Reticle System (MRS), letting the shooter choose between a precise 2 MOA dot, a fast-acquisition 32 MOA circle, or the combined dot-and-circle reticle on the fly. The Gold Dot LED produces a high-contrast aiming point that pops against darker targets and shaded backgrounds, and the sight remains parallax-free with unlimited eye relief for natural pistol presentation.

Solar Failsafe keeps the reticle powered by ambient light when conditions allow, while Shake Awake activates the LED on motion and conserves battery at rest when the optic is idle. The HE509T X2 uses an RMR footprint and mounts directly to optics-ready duty and competition pistol slides. Nitrogen-purged and sealed for waterproof service, the HE509T X2 is built to keep running in the harshest environments.
