Compact, battery-frugal, intuitive operations, easy transition circle-dot sight picture.
Like new, complete packaged in the original manufacturers padded box. Provides a very clear dot surrounded by a circle. Very visible, easy to pick the reticles out of the background optical noise. I am awaiting hardware to mount it to my shotgun. If I figured right, the 65 MOA diameter circle predicts pretty accurately the size of a buckshot pattern. We'll see soon!Verified purchase: YesCondition: Pre-owned

Green dot sight- when it works
Compact, well made, easy to see green dot. That was my first impression. After having it for a couple of months. I am very disappointed. Battery won't hold a charge more than a couple of weeks, even when turned off!Verified purchase: YesCondition: New

Great budget priced green dot sight!
Outstanding budget priced green dot sight. I have problems with red dots due to astigmatism, but for some reason not so much with green dots. This Holosun is a good quality dot sight in a compact format. Zeroing was easy and straightforward.Verified purchase: YesCondition: New
