Description
The Holosun HE512T is a rugged enclosed reflex optic built for rifles, PCCs, and shotguns where durability, visibility, and speed matter most. Its Grade 5 titanium housing and Multi-Reticle System deliver a wide sight picture and adaptable aiming – run the 2 MOA dot alone for precision, the 65 MOA circle for fast pickup, or the circle-dot together for both.
Solar Failsafe and Shake Awake keep the optic powered and ready, drawing on ambient light for automatic brightness and backup power while motion activation wakes it instantly. The included absolute co-witness QD mount sits at a 1.41″ height for natural alignment with AR iron sights, and a side-loading CR2032 tray makes battery changes simple. Sealed to an IPX8 rating, the 512T is ready for hard, all-weather use. Available with a red or green MRS reticle.
