    • Blown Away. Snooze you will lose out...!!!
I was looking at several brands. Some pricey some cheap. After watching You Tube videos for hours and reading all the Amazon reviews took a chance and boy did, I do good...!!! This is amazing for the price. It is way better than I expected. People have a tendency to stretch the truth sometimes. So, I was leery. But man, oh man is this a nice sight. For the money, you cannot do better than this. No way, no how. Green isn't really green. It's more of a green gold. Super nice. Dial it up or down till you find perfection. Great Buy...!!! Built like a tank...!!! ... show more

    • Super clear
I tend to stick with the tried and true brands like Trijicon, but I wanted to try this brand. I’m impressed with how well made this is. Nice glass, great visibility of green dot. Very cool kit.

    • Love This Optic!
Great unboxing experience and easy to install. Went to a friend’s outdoor range and put over 500 rounds chambered in 556 ammo and optic never moved out of place. The functionality and placement of the buttons feels nice and tactile. Time will tell with battery life but I’ve owned other optics from Holosun and it’s never been an issue. It is lightweight and doesn’t add much weight when mounted on an AR-15. Shoutout to the staff at Holosun for engineering a superb red dot. Build quality is phenomenal and value for money, 100% worth it in my honest opinion. It is zeroed from factory and can easily hit a small steel target from 100 yards. I love that about Holosun. No complaints about this optic so far! ... show more

    • Perfect
This is definitely my most favorite recent purchase from Amazon. I was looking for a cost effective alternative for my AR rifle. This green dot sight is absolutely perfect. Multiple reticles and differing brightnesses along with stay awake times make this perfect for me. It’s even flat dark earth color to match my rifle. ... show more

    • Great reflex sight
I returned mine after buying the wrong color and I didn’t receive a refund for 4 months. Other than that these are top quality reflex sights. Right under eotech in my opinion

    • Quick shipping
Exactly as described, item shipped way sooner than expected. Only concern was the packaging, it came with just paper filler and the box the optic comes in.

    • good alternative to EO tech
Does same thing and half as much. Has features that make me happy. Shake awake, solar backup, solid construction. I'm now a fan of Holosun. Got the 3x magnifier also Nice combo to terminate dangerous predators
