  • Actually new and works great.
At first I thought I received an used item because the battery was alredy installed and saw what I thought was a defect on the lens. I had started a return and decided to buy one in person at a local store. It turns out though after looking at one at the store. The pre-installed battery is apparently normal on this holosun model and the ones at the store came the same way. So I decided to keep it. Also, the glare I thought I could see was only because I was indoors and looking too close into lens...once outside and mounted, the sight looks great with a perfect red dot or reticle and there is no glare. Great eye relief and the magnification works great too. ... show more

  • Outstanding Performance in every way!
Worth every penny, top quality combination. Great addition to your rifle, easy installation, clear bright zero, combine the 3X with the dot opens up ability for accuracy you never imagined. The 3X flips over to still allow use of your iron sights. Top quality in every way possible, easy to recommend. ... show more

  • Flip to Side = Epic
"Violently designed like the Trolls of Asgard Silencers the size of a grown man's arm Listen, the scope pivot like a cyclops Chrome so heavy the shooter had to use a tripod"

  • Good initial impressions
I just received this item. Looks brand new, minimal wear on the pivot joint for the magnifier. Easy installation with toggle levers. 2 tools provided to adjust tension so you can adjust the toggle levers to fit tight and still be able to open it. Once adjusted, it fits tight with no wobble. Adjustable brightness is great for various lighting conditions. Magnification looks clear, and I like the provided elastic cover. From use with previous dot sights (5 moa) I thought I had an astigmatism. Maybe I do, but if so, this sight minimizes the starburst effect and would be completely usable. Will update after use. ... show more

  • As Good As EoTech
I've owned EoTech sights and the Holosun 510 is just as good in terms of performance, features, and quality. The Magnifier is excellent, but the eye relief is not sufficient for my Marlin 336. With the magnifier installed as far back on the receiver as possible, it needs an additional 1 to 2 inches of eye relief to accommodate a comfortable cheek weld. ... show more

  • Very impressed with initial quality
Build quality is high for price point. Easy installation and warranty registration. Time will tell for longevity, if I run into any issues, I plan to update. Did a lot of research before buying!
