Red dot sights reviews: Awesome for the price. I had the original red dot sight as well and the build on this clone is excellent. Red dot is crisp, when the green is on I see a tiny glare but not a big deal. Original one has less glare on the glass but other than that I have no complaints. Held zero so far no issues. Shipping took a little less than two weeks from China but I can say it’s definitely worth the wait for the amount you would save.
