Holosun HE509T Open Reflex Sight
The Green Series from Holosun incorporates many critical innovations and performance features that are more than just “nice-to-haves’. When the effectiveness and dependability of your optic can make the difference between success and catastrophe, you want every advantage on your side of the lens.
The Holosun Story
If you’ve been shooting for accuracy for long, you are probably well-acquainted with the commitment to driving new ground-breaking technologies that Holosun brings to the shooting optics category. But you might be surprised to know that its collection of optic and laser/infrared devices comes from a company that only started up in 2013. In that time, users whose applications range from recreational shooting and hunting to law enforcement and military missions have come to trust the company that has moved to the forefront of the industry. By creating important features such as Solar Fail-Safe technology, battery efficiency that lasts up to 100,000 hours and its signature multi-reticle system (MRS), to name just a few, Holosun stands out in a crowded field.
“When the effectiveness and dependability of your optic can make the difference between success and catastrophe, you want every advantage on your side of the lens.”
Bringing these capabilities together in cutting-edge products that offer superior durability and quality at affordable prices, adds up to industry-leading value and performance that demanding users appreciate over the lifetime of their equipment.
Function Comes With Form
The HE509T is designed for deployment on pistols. Its green Multiple Reticle System includes both a 2 MOA dot and 32 MOA circle reticle and it is protected in a titanium housing. Super LED technology enables adjustment of the reticle’s intensity to suit all environments from the brightest to the darkest.
The user-friendly Shake Awake feature eliminates the need to manually protect battery life with an automatic Sleep Mode that can be programmed with four options. Likewise, the unit’s on-board motion sensor will activate the LED when it senses the slightest movement. A CR1632 lithium battery is included with the device and has a life of approximately 50,000 hours.
The HE509T also benefits from Holosun’s Solar Failsafe Technology which uses a solar cell to enable the unit to run even when the battery fails. In addition, the brightness of the reticle is automatically adjusted as you move through different lighting environments.
The optical glass is manufactured with multilayer coatings that allow maximum light transmission and wear resistance while also reducing glare. Holosun’s Grade 5 Titanium housing has up to twice the tensile strength and five times the fatigue strength of 7075 aluminum and it is also unaffected by seawater.
The low profile and light weight of the HE509T are almost unnoticeable, having no real effect on balance. At just 1.6 x 1.16 x 1.13 inches and 1.72 ounces, you won’t know it’s there until it’s time to use it.
