Holosun 509T First Look

The FN Pervue is introduced as FN's first micro orthographic red dot sight, leveraging waveguide optic technology from the augmented reality market for a more compact design. This new optical architecture uses image guide technology to create a true orthographic sight where the dot is an image, not a reflection. It features an on-axis light path directed to the bottom of the glass and conducted to the user's eye via a nano structure, resulting in a clear, tint-free, flat lens with no optical aberrations. Designed to be ruggedized yet lightweight and compact, it was initially developed for pistols due to their demanding nature for red dot sights, and has been validated on other FN platforms to meet robustness standards. The Pervue signifies FN's broader optics strategy and commitment to integrated solutions.

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.

This guide explains the differences between open and closed emitter red dot sights. Open emitters offer a wider field of view but are more susceptible to dirt and oils, making them better for open or duty carry. Closed emitters provide superior protection against environmental contaminants, making them ideal for concealed carry and harsh conditions. Both types are functional, but the choice depends on the intended application and user preference for maintenance.
