    • Get it, love it
Color: Black Style: Green Dot
This thing is awesome, it is super clear, massive window, and built very well. Goes on easy and windage adjustments are simple and accurate. The charging function which appears as a gimmick is really not, it works its simple, and honestly its nice knowing you have a way to keep this going for years on end. Its battery will likely outlive the dot in regards to we tend to replace them well before the dots ever truly go down. Packaging is awesome as it came with tons of screws very well packed up that far surpasses more expensive options. Im a believer and for the amazing price its a no brainer. ... show more

    • Very nice optic
Color: Black Style: Red Dot
I can't find anything wrong with this optic and believe me I tried it's a very well thought-out design. Goes on easy Large sight picture. It's easy to charge several brightness settings 12 I believe. But one things I like the most is when you buy this you get a lifetime warranty no questions asked.

    • Great!
Color: Black Style: Red Dot
Still pretty new to the pistol RDS game but so far this seems to be of great quality and build. Plenty of adjustment for the brightness of the red dot. Only used at indoor range so will update after use at outdoor range. Easy to use, easy to charge, and seems to provide all needed functions for my style of shooting. ... show more

    • Tested on 10mm Smith M&P
Color: Black Style: Red Dot
Optic flew off the gun under recoil even with extra blue Loctite added with the recommended 17 inch torq spec (wheeler fat wrench). 3-5 rounds of underwood hardcast. To the credit of the optic it got scuffed on the top corner (still seems to charge) and I mounted it on a different firearm. Still seems to hold zero. I wouldn't trust it on any sharp recoiling semi auto handguns. The mounting hardware seems like a joke and the default loctite doesn't even contact the surface where the loctite is needed. I bought different hardware, retained the 17 inch lb torq spec and mounted it on a 556 ar on a canted mount. ... show more

    • Does not hold a zero

I want to like this sight, I really do. The rechargeable case is a really cool concept. However it does not hold the zero. I zero'd the sight using a laser boresight, shot 50 rounds of 9mm, and it had already drifted off of the zero. I rezero'd it. It seemed to be resistant to me smacking it with my hand and on the table but once I put another 50 rounds down range it drifted off of the zero. I can not recommend this product because it can not be relied on. So in total I've only put around 100 rounds of 9mm, so maybe it just needs more time, but it is not a good first impression. Edit: Don't know if this will upload in the right order but the first image is after sitting in my holster and nightstand (after I had already rezero'd). 2nd image is me zeroing it again. Third and 4th image is after just swinging the gun in the air like a madman. Not even shooting. Edit 2: Ended up getting sent another OSight and it ended up un-zeroing in the same exact way. Decided to get a Holosun 507 Competition and I'm much happier for it. Not getting the same zero issues with the Holosun. I am disappoint that I'm going to be missing out on the auto-brightness and the rechargeable sight but being able to hold a zero is non-negotiable. Hopefully they get this issue ironed out. ... show more

    • Quality and value
Color: Flat Dark Earth Style: Red Dot
Nice clear picture. Love the charging/dust cover. Red dot is clear and bright. Dot can be manually dimmed, or it can be put in auto mode to automatically adjust under different light conditions. Unlike cheaper units, the adjustment screws turn firmly so I'm sure it will hold true. The desert tan matches my FNX 45 TACTICAL PERFECTLY. THERE IS ALSO A STORAGE BAG FOR THE COVER. CHARGE HOLDS FOR A VERY LONG TIME. ... show more

    • Works great for practical shooting or defense.
Color: Black Style: Red Dot
I have long been the guy who gets tormented by the other guys in my squad for using OLight lights on my firearms and have yet to have been given a reason, by them or the products themselves, to stop and pay 4 times as much for a surefire. So when I saw OLight made a red dot I had to try it out. It works great. I mounted it on my Echelon using the factory RMR pins with no issues and it's rock solid. Zeroed @ 25m with less than 15 rounds and held for about 300 rounds no problem so far. The charging case is convenient and easy to use, shake awake works great, and the window is HUGE, like SRO or CMore huge. Some folks like that, some don't, but I think it gets me on target faster while competing. I normally run an EOTech EFLX on the Echelon but I think the OLight is going to stay on there for a while, at least to see how it holds up after a couple of months and a few thousand rounds. I did drop the gun on concrete with the sight on it already and it didn't have any issues. UPDATE: 6/5/25 Still running on my Echelon with zero issues after a thousand plus rounds. Haven’t had to charge the cover still and rarely have to even put it in the red dot. Solid buy for sure if you’re not a hardcore tactical LARPer and want the Trijicon or Aimpoint cred. ... show more

    • Rechargeable red dot
Color: Black Style: Red Dot
This is a brilliant idea. A rechargeable red dot at a great price. It comes with 4 different screw sizes with 2 lengths for each size (essential as I needed 2 different sizes - one for a plate and one for the dot onto the plate). The charging cover is magnetic and seals the dot preventing solvents and oils from fogging the dot when cleaning the gun. The dot is small and precise. I did not find the auto brightness adjustment bright enough but the buttons were easy to press and I found a brightness I liked. Mounted on a Walther pdp it needed no adjustment and I shot 2 inch groups with 3 out of 10 bullseyes at ten yards. I am 75 years old. Just buy it! ... show more
