  • Great sight setup
Perfect affordable setup. Works great and holds zero well. Have used it to 300+ yards

  • 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

  • Totally blown away
This combo is simply fantastic. Starting with the magnifier, it seems very durable, mounts with QD, gives good 3x magnification and folds out of the way (and stays out of the way) until you need it. The dot itself is built like a tank. Has auto off, shake to wake, an extremely crisp dot with excellent glass and an awesome solar back up feature in case the battery dies. I am very satisfied with this purchase and it definitely feels like I got more than what I paid for. ... show more

  • The go to "Budget" Red Dot Magnifier combo.
After messing around with a few other optics such as the Sig Romeo Juliet combo and not being a huge fan of the magnifier glass, as well as not wanting to drop over a grand on an eotech combo. For your avid range goer who doesn't really do anything crazy that'd need the durability as like an eotech stated before, this optic is perfect for you. Multiple reticle options to switch on the fly, as many brightness options as you'd need, great battery life, shake awake, and more. Would recommend for anyone wanting to dip into the magnifier space without spending a small fortune. ... show more

  • Great set-up
Great product. The magnifier is fun for really dialed-in accuracy. Very easy to sight-in. Just make sure that you have opposite laser and green-dot colors.

  • Amazing package for the price
Just wow. This configuration is just amazing. The 3X optics looks so clear with great eye relief. I'm highly impressed with both items

  • Better than EOTech unfortunately
Crystal clear reticle, and great little magnifier. Seems super rugged, but I won't pretend I'm in the trenches. Maybe the EOTech can go deeper in water (never gonna use), or the battery last longer (Holosun seems incredible with the little solar panel and shake awake btw), but for someone who just enjoys shooting and being prepared This is the way to go. I have both of these units (Holosun and EO) on identical rifles and I reach for this one every time. Not saying the EOTech isn't a good product, but for less than half the cost, grab this one. Only drawback is this unit is made in China (still a super high quality product) I'm big on supporting USA but come on, at least be competitive on price. ... show more
