    • Great optics, low cost
Color: Gold Style: Multi-Reticle
First and foremost what drew me to this uptake is the gold sight. If that's something you're looking for this will do just fine! The exterior quality is top notch. Easy to turn on, change brightness levels and also easy to turn off. The gold radical Kim return very bright and it will perform just well in bright sunny days. Alternatively, The dimness levels can be set very low for those low lighting conditions. Well negative that I will have to note is that there is a definite bluish tint inside the sight which may be a turnoff for some looking to have a clear lens. Though highly noticeable, it doesn't diminish it's utilitarian purpose. Overall a good and trust worthy uptick with a good price tag. ... show more

    • Extreme quality low price. Just buy it.
Color: Gold Style: Multi-Reticle
Absolutely great optic for the price. Holosun knocks it out of the park again. Reticle is super crisp. Build quality is robust, heavy, and has a premium looking matte finish. I love this optic and love the price point. I have it on a Unity riser, and the risers footprint is a tad longer than needed but unless you look close its not noticeable. Obviously it holds zero well. If you have an astigmatism the gold dot hardly starbursts. I truley dont think theres another dot in this price point with a build quality like this. ... show more

    • Not for eyes with astigmatism
Color: Gold Style: Multi-Reticle
The gold circle dot is supposed to be better for eyes with astigmatism but after trying it I’m disappointed to report that it’s not, at least not for my eyes. Otherwise, it’s a really nice ultralight optic, feels like quality, class is clear, and controls are good.
