Holosun HE508T-GR X2 Reflex Sight — Titanium

Holosun HE508T-GR X2 Reflex Sight is an open-frame pistol optic designed to provide a clear, unobstructed sight picture for handgun applications. Manufactured by Holosun, this green-dot reflex sight uses a selectable reticle system to support fast target acquisition and precise aiming across duty, carry, and range environments.

The HE508T-GR X2 is intended for shooters who require a compact, durable pistol optic capable of withstanding hard use. Its open reflex design offers unlimited eye relief and a wide viewing window, while the Multi-Reticle System allows users to tailor the sight picture to their shooting style or conditions.
