Holosun 509T Raises the Bar for Open Reflex Sight

City of Industry, CA (September 16, 2020) – The 509T open reflex sight is a staple in the Holoson line-up and for a good reason. Pistol owners love the lightweight, ultra-durable enclosed design. The 509T offers a “set it and forget it” sight that snaps into action when the shooter is ready. The incredible battery life and performance qualities make this sight a major tactical asset for any shooter.

Holosun incorporates the highest quality battery technology available into every sight offered. The 509T is no exception, and the battery will last for up to 50,000 hours. The solar failsafe adds a layer of security, ensuring shooters will always have a powered, active and effective sight. The convenient battery tray compartment also makes for easy replacement with a CR1632 model battery.

The entire unit is enclosed with a titanium housing that protects the super LED internal components by keeping the elements at bay. Multiple coatings are added for additional protection against dust and moisture. The durability is phenomenal, and the compact design makes for a natural extension of the pistol. Shooters will not notice a difference in grip or weight when holstering or gripping the pistol, as it weighs a mere 1.72 ounces. 

Sight options include the 2 MOA Dot or 65 MOA Circle, giving the shooter options based on personal preference. It also includes 12 brightness settings for tactical shooting in different light conditions. Shooters can transition seamlessly between bright sun and dark corners while maintaining an ideal brightness setting. Additionally, the parallax free, unlimited eye relief prevents fatigue, allowing the shooter to maintain focus throughout the entire tactical event.

Holosun is proud to manufacture the best open reflex sights available, and the 509T excels in the field. The combination of performance, durability and integrated design features make this sight a major asset for any tactical pistol shooting scenario.
