Holosun 509T: Why Green LED Reticle?
Here’s why this is a great feature: as our eyes age, we don’t see colors in the RED spectrum as well as we used to. Red light is on the shorter light wavelength spectrum and as such – you can think of it akin to hearing – the shorter the wavelength (or higher frequency for sound) the harder it is for older eyes to pick up and differentiate from other colors.
Studies show that, with practice, people with both young and older eyes see colors in the green spectrum more easily. This pays off on a pistol sight, which allows the shooter to acquire the target more quickly.
Holosun HE509T-GR X2 User Reviews
To understand what users think about the Holosun 509T, we checked user reviews on Amazon:
“Only time will tell how it holds up to lots of semi-auto shotgun rounds but I do like it, particularly for a shotgun due to the multiple reticle options. The open hashed circle is perfect for buckshot while the dot is perfect for slugs. It co-witnesses my ½-moon peep sight which is nice (Aridus?). Multiple setup options and I also really like that while it takes a battery it mostly relies on solar when it can. I only wish they used something more common like a 2032 battery. CR1632’s aren’t all that common. Also I have fairly bad astigmatism but this is one of the best RDS’s I’ve ever used in terms of very little flare.”

Love these optics. Very reliable and more than capable. I have 6 RMRs and more than 10 Holosun handgun optics… not to mention rifle optics and LE illuminators. I’m certainly a fan. I’ve sold many ither RMRs from my past, but, among the other brands and models we’ve owned/tested, these stand out for good reason. Phenomenal unit and well earned accolades by our own folks that TAKE IT PERSONALLY, to assure these things stand up in way most will expect. Good on you keeping the word out!👍🏼
