Great budget sight
Pretty good sight to me. Has decent build quality and nothing feels too cheap. Very large and clear glass, great for two eye shooting. Mounts up good on my 5.56 and hasn't lost zero. Maybe not entirely battle ready, but for what it is I think it is great for the price. Would buy another if they ever come out with an FDE or tan color ... show more

Nice product for the price. Not a single problem
Work very well, I have purchased two of these and have had zero problems or issues.

No protective cap?
Overall a decent sight. Not really a fan of this version of the sight not coming with a protective cap like the smaller and less expensive version does.

So far, so good.
Everything is fine so far with my optic. The reticle is clear and crisp. The housing is made of aluminum. My only gripe is that the instructions were printed in Chinese so I couldn’t understand them but if you have any problem solving ability and experience with optics then it’s not hard to figure out. The “shake awake” function does work but it also has an option to manually turn it on and off. If you want the “shake awake” to work, you have to let it turn off on its own. If you manually turn it off, you’ll have to manually turn it back on but turning it off and on is done by pressing the button on the side. To manually turn it on, you just press the plus button. To manually turn it off, you have to press the plus and minus buttons at the same time and hold them down until it turns off. Overall, my experience with this optic has not been bad. ... show more

Good budget scope
A bit weighty but good overall

Quality consistency might lack
First one I received the side buttons didn’t work well the + worked fine but the - barely worked almost impossible to get it to turn off or brightness down. Received a replacement that seems to work flawlessly zeroed in about 8 shots and holds dead on.

Wiring issue or a short.
Not sure about all, but mine is junk. You can barely see the dot against something dark and the batteries get really hot, really quick. The batteries are in correctly as +/- are clearly marked on the sides. Something is likely shorted out.

This sight flips the script.
Hands down best sight I've bought. Bought 600 to 800 hundred dollar for builds thinking it's the only way. Building this low budget 300 blackout thought to give this a try. Looking for a large veiw for older eyes. Wow at this point I regret 600 to 800 hundred dollar "names". This is one of the best sights I've bought. Hands down no question. ... show more
