Osight 3 MOA Rechargeable Dot Open Reflex Sight with Charging Cover, Tactical Parallax-Free Sights, Picatinny Mount Compatible - Green/Red Dot Options

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.

Looks and works great. Great price too. I really like the rechargeable cover and the battery life.

Just for context I have an SRO, 507 comp an RMR. I am ditching the SRO going forward and if over the next year, this holds up - will then ditch Holosun. The window is huge and the dot is clearly visible. I do wish they had more reticle choices however this thing is an amazing deal for the money. The charging is system is best in class.

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.

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.

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.

So I have been a Holosun 407/507 type of guy, but after I found out that an Olight warehouse is right around the corner from me and I've used/have many Olight products, I had to try it. Well, I AM NOT disappointed. It looks great on my weapon system; I love the shake-wake function and the fact it can be charged a few different ways. I am impressed by it. I will take it to the range here shortly and see how it holds zero. If it does, I think I've found a new red dot.Impressive

Great product. Very good price. I'm very happy. Charging very easy. I installed it at the gun shop.
