The Holosun 509T-RD X2 hard-use, nitrogen-purged enclosed pistol sight with a red 2 MOA dot and 32 MOA circle (part no. HE509T-RD X2) is built for demanding handgun applications. Holosun houses the optic in grade 5 titanium and runs Holosun’s Super LED for up to 50,000 hours of battery life, backed by Solar Failsafe and Shake Awake technology. The X2 revision adds improved glass clarity, a Lock Mode that prevents inadvertent setting changes, and a full Multi-Reticle System offering the dot only, circle only, or a combined circle-dot pattern. An included adapter plate provides compatibility with RMR-style footprints, and 12 intensity settings include two levels compatible with night vision devices. Among enclosed-emitter red dot sights, this 509T-RD X2 configuration favors duty and hard-use handguns.
