Questions & Answers
Why does the green cost more? Expert Answer

Green dot sights like the Holosun HE508T-GR-X2 Green Dot Sight generally cost more because they are brighter and stronger than red dot sights. The green dot sight is generally brighter can be seen better in daylight compared to red dots.

worth every penny by bigrob, Verified Owner, July 7, 2025
Becoming one of my favorite optics to run on my pistols. Perfect size. Doughnut of death or just the dot. I run both depending on my mood. Green is an added plus. Solar. What more can you ask for. Holosun is killing the game.

Holosun 508T by Dan S., Verified Owner, August 10, 2025
This is my 1st Holosun green dot optic. I put the 508T on my Marlin Dark 1894 rifle. Looks good, zeroed easily, accurate and built tough. We'll see what the future brings, so far I'm really happy with it.

Short Range Sight by MIck, Verified Owner, October 10, 2025
While I’m shooting my new long range, bolt action build, what happens if a threat pops up at close range? The ideal solution is a Holosun 508T riding an Arisaka Defense offset mount.

Awesome titanium sight by John, Verified Owner, December 3, 2025
I mounted this on a RMR Dove Dot mount on my Glock 19 gen 5. Works perfectly. I can shoot groups within 3 inches. Plus was given a great price!

Excellent Product by Kage, Verified Owner, November 15, 2024
I recently was looking for a red dot for my FN Five Seven and the 508T fits perfectly, it’s fairly durable and the instructions on operation are intuitive enough. If you’re looking for something that is low profile and reliable, consider this optic.
