Love this green dot


Love this green dot. Especially with the "shake awake" technology which increases battery life to 50000 hours. Great reticle, great clarity and great price. Pair that with fast shipping from Primary Arms and it's unbeatable.

Holosun is usually my go to Red or Green Dot for and of my guns. I have never had any problems with any of mine at all. I have found that I have a very bad astigmatism and the green works so much better for my eyes. I only ever use the single dot on any of my rifle Dots so no need for the upgraded version reticle that has circle and dot. For the price these r very hard to beat on a AR15 for short range. I would recommend this dot or any other Holosun if u r still on the fence about what brand to run.
