The Holosun HE509T X2 Gold Dot Sight is a hard-use enclosed pistol gold dot sight built for durability and fast acquisition. Its Multi-Reticle System offers a 2 MOA dot, 32 MOA circle, or circle-dot — switch between precision and speed at will.
A Grade 5 titanium housing, improved glass clarity and Lock Mode handle demanding use, while Solar Failsafe and Shake Awake extend runtime and keep it ready. The enclosed emitter shields against debris, and an RMR-to-509T adapter plate is included for wide pistol compatibility.
