OLIGHT Osight 3 MOA Dot Rechargeable Green/Red Dot Optic, 407C/507C Footprint

Really impressed with this red dot, I was a little worried about recharging but I’ve had it a while now and it’s still fully charged. For the money I can’t see paying the difference, but I don’t shoot as much as I used to so it works and looks great for me

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.

Held zero for my first 150 rounds no problem. Will update the review if anything changes. Do not use the included tool to install the optic, it should be torqued down if expected to hold zero. Window size is great and the dot itself is quite clear. Hangs a few mm off both sides of a Glock 19 slide but it still looks good. I cannot speak on the quality of the material but the finish is slightly lesser quality than my C&H EDC optic. I managed to slightly scratch the finish with my t-tool during installation. Otherwise, this is a very competitive optic for the price. I imagine I will continue to use this optic should it hold zero.

The problem I reported with the damaged equipment was due to improper operation. I plugged the scope and magazine into the AC adapter to charge. Of course, it didn't charge; it turns out I should have loaded the magazine first and then plugged into the scope. Thanks to a YouTube video, I discovered my mistake, so the equipment is perfectly fine and I don't need to replace it. Going forward, I would like to request that you provide documentation explaining how to operate the equipment and not leave it to the customer's skill.

You want a dot? You want it to work good? Get this one. Best price, big window, clear glass, tactile click adjustment, tight fit, durable, just a win.

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.

(Glock 19 clone build) Fit on an aftermarket slide (wolfe, ebay). It's my daily carry. Setup is a gritgrips frame, wolfe slide, extended controls, and this sight. I'd trust it with my life. I love the magnetic charging case that just snaps to the unit. I've had this for quite a few months and haven't needed to charge it. I'm gentle with my firearms, so I don't know how it compares to more expensive units, but I'm confident in the sweat and everyday bumps. I'd buy it again.

I purchased this red dot and was extremely happy with it. I went shooting with it and the dot was right on. No problems with recoil, it held perfectly. For the price you absolutely cannot go wrong. When I got home and was cleaning the gun I accidentally dropped the slide breaking the glass on the red dot. I was so upset but went online and Olight Warranty had a form to fill out for warranty work. I explained what happened and that I wanted to get a price to have it repaired. They immediately sent me a paid return packing label so I put it in the mail. In the meantime they sent me a receipt saying they were going to replace the red dot no charge. I couldn’t believe their customer service was so fantastic, I just wanted to get it repaired. Well today I received the new red dot and had to give them a great review. If you’re looking to purchase a red dot this is the Olight is the best place to buy one. Thank you Olight for the great customer support!
