HOLOSUN 509T 2 Year Review (It Broke)

Published on December 28, 2024
Duration: 4:07

This two-year review of the Holosun 509T highlights its performance and durability issues. While praised for its large tactile buttons, excellent auto-brightness adjustment, and robust titanium housing that survived rain, snow, and desert conditions, the optic developed stress fractures in the glass after two years. The reviewer notes the sensitive 'shake awake' feature drains the battery quickly, requiring frequent replacements. Despite the glass damage, the optic surprisingly maintained zero, though the cracks are visually distracting. The reviewer plans to submit it for warranty repair.
