    • Amazing for the price and holds a zero
Color: Black Style: Green Dot
Bopught two of these for pistols. I have had zero issues with either of them. they both have nice clear glass and a larger window which makes target aquisition easier with 46 year old eyes. The brightness adjustment is nice and the green dot doesnt wash out against backgrounds that are bright. I have one on my prodigy comp and have put almost 4k through it with out losing zero. Recharging the unit is nice and simple to do instead of having to swap out batteries. I pop the top on when I am done and it charges it for the next go round. Charging the cover doesnt take long and magnetically attaches to the sight which is nice. The housing is made from aluminum so it has been durable for me and has held up to all that I have thrown at it. One cavieat is that the screws that were provided are made from cheap metal. I would not recommend them. Save yourself the hassel and use higher quality screws. ... show more

    • Good budget sight
Color: Black Style: Green Dot
Nice sight picture, charging system and size. It’s made for a FULL size handgun but can easily be used for an SMG or shotgun is so big. Dropped it a couple times has held up but not trying to break it. Rated 4/5 as there are better options but they are also pricier. Worth the money but if you’re thinking of getting a better brand just buy once cry once. ... 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

    • Does not hold a zero
Color: Black Style: Red Dot

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

    • Awesome optic at a killer price. Do it.
Color: Black Style: Green Dot
I wasn’t sure what to think or expect with this optic, but I’m super impressed. I have a ton of Olight lights, so I figured I’d take the risk on this and see what I think. Mounted it up piggybacked to a scope and it’s amazing. This model doesn’t have multiple reticles to choose from and is just the 3 MOA dot, but that’s what I needed for this build. The fact that I don’t ever have to dismount it to change a battery is amazing, and the charging cover is sweet. It installed easily with two screws like normal, is easy to use and program, and seems to be great quality and zeroed easily. I’ll definitely be buying more for my other toys. ... show more

    • This green dot works with astigmatism
Color: Black Style: Green Dot
I have pretty severe astigmatism and could never use any red dot except an EO tech. It’s a squiggly line that starts at the top left and runs at a 30° angle to the bottom right. I chose the green dot 3MOA site and it is fantastic. At the lower light settings it is a real clear dot. I have it mounted on a Taurus TX 22 competition pistol and the adjustments are superb. The MOA clicks are very distinct and work well. The rechargeable cover works better than I thought it would and I am really pleased with this site. I am going to order a new slide with the optic cut out for my Glock 21 and I’m going to buy another one of these sites. ... show more
