I really like this sight! I got my first carry gun and just need a little bit of budget friendly option when it came to sights as there was nothing on sale when I was looking. I looked at the reviews and did some research and found myself looking at the Olight line of sights. Ultimately went with this one based on reviews and price tag and let me tell ya it wasn’t a mistake. The sight is nice and seems very durable. It’s easy to sight in and has nice adjustability when it comes to brightness. Love the 3 sight options too! Shake awake is a must on my carry gun. So far it holds zero pretty darn well. Unsure of its battery life as I’ve really only had it a short time but I’m sure it’s a couple years with normal use. When installing I recommend that you pay attention to the proper screws for your firearm and torque it down to the proper torque or it’ll come loose. Overall highly recommend it! Great sight for the price and you won’t regret the purchase.

I’ve been running the Osight C micro red dot on a pistol with an RMR-pattern slide, and so far it has been a solid optic for both range use and training. The 3 MOA dot combined with the 32 MOA circle reticle is one of the main reasons I picked this sight. You can run the dot only, circle only, or both together, which makes target acquisition very fast while still giving a precise aiming point.  The glass clarity and window size are better than I expected for the price, and the larger viewing window makes it easy to pick up the reticle during quick draws or transitions. Brightness adjustments are simple, and the dot remains crisp even at higher settings. Another feature I really like is the side-loading CR1632 battery. You can swap the battery without removing the optic or losing zero, which is a huge convenience compared to bottom-battery designs.  Things I like most: • Multi-reticle system (3 MOA dot, 32 MOA circle, or both) • Clear glass with a large viewing window • Side-loading battery so you don’t have to remove the optic • Motion sensor wake-up feature to save battery life • Standard RMR footprint fits many optics-ready pistols  One small note: it’s not as ultra-compact as some micro optics, but the larger window actually makes it easier to track the dot during rapid shooting. Overall, this feels like a great value red dot with features normally found on more expensive optics. If you’re looking for a versatile pistol optic with a fast-acquisition reticle and easy maintenance, the Osight C is definitely worth considering.

Osight is quickly becoming my goto for my pistol optics. The fit was spot on and the quality is great. Very very clear glass and a crisp dot. Works great in full daylight and holds zero like a champ. 1200 rounds and still holding. Good size window as well. I dont personally "torture test" my optics but I think durability won't ever be an issue

After having issues at the range and just with the sight in general the seller sent me a replacement and it’s impressive to say the least. It’s very clean and durable it hasn’t lost its zero since the replacement the seller genuinely cares about their product and they stand behind it which is rare!!! Shot over 500 rounds with no issues. It’s reliable and accurate the screws they send over cover a multitude of thread sizes. It has everything you need perfect for the ruger rxm!!

Review of the Osight C, in my case the green dot version. So the first impression of the optic is that it appears really well built. I tried to capture some good quality pictures. The packaging is almost "Apple iPhone" feeling. You can tell the company truly put their time and energy to build and release a good quality product down to how they package it. I purchased this particular optic for my custom optic cut slide for my Glock (shout out to GlockStore). With the RMR foot print and the price point I was excited but skeptical. I've had this sitting in my Amazon cart for weeks, watching videos of teardown/durability test. After finally making up my mind I choose the Osight C Green Dot. Now, as of me writing this review, I haven't got my slide back to actually mount the optic but these are initial thoughts. The quality of the green dot (which the pictures don't do it justice) is really great. The glass is very clear and looks incredibly well made. The radicle is crisp and clear. I enjoy the option to choose between just the dot and the circle dot. Green really helps me as my Vortex Defender CCW (red dot) sometimes looks blown out. The optic comes with a soft TPU feeling cover to protect it, good especially for storing or range trips. In the packaging comes an assortment of mounting screws for various slide cuts, operation manual, a branded cleaning cloth, extra screws for the battery tray and a convenient bit driver for installing/maintaining the optic. The optic came with a 3 volt, CR1632 button cell. These batteries are pretty standard and last a while, just change it on your birthday every year and it should be good for another year. If it dies you can easily get one from just about any store for cheap. I should also mention that there is a yellow card included that shows the installation process and torque specs for the various mounting screws. Overall, off of first impressions, I love it. I think it's going to be a great addition to my collection and I'll enjoy it on my newly cut Glock. I'll update this review after I go to the range and sight/test it further.

Long time shooter with a lot of experience with different types of firearms and set ups. Typically for budget optics I go with Holosun and Sig depending on the platform. I saw a few reviews on this as well as some really good coupons and figured I would give it a shot. It’s packaged extremely well, great directions, a large amount of different size and length screws depending on your firearm which is big, and the price itself is made extremely well. It has one of the clearest and most crisp reticles out of any other pistol optic I have ever used including the big 3. That being said I gave it 4 stars because I haven’t used it long enough to make sure there are no issues with it. With a lifetime warranty I’m not really worried. I wouldn’t go trading in all your Aimpoints but for range application or shooters that just want to try a red dot you can’t go wrong even at its full price.

Best red dot I've ever owned for pistol. Of course I only have the original Shield RMSc, but I recently purchased an Osight SE as well and that is great too, but this one is fantastic. Green dot is very clear and have the option for the 30 MOA circle. Very easy to adjust the brightness and the battery last forever according to the description. I haven't had it long enough to prove this. This is the best red dot you can get for this price range. It is VERY economical when put side by side to it's competitors. It's very solid as I have been able to rack the gun on my jeans using just the sight which is great. Definitely pick this one up for your full size weapons.

I was blown away with this one! First off, I’ve only run Holosun optics on my pistols. I’m a firm believer in consistency and quality. This optic is just as good as the “other” ones I own. A multi reticle 2 MOA dot that holds its zero for under 200 bucks sounds too good to be true. However, I took the leap and am glad I did! First true run was at a USPSA competition and it worked great. Shot 90% of my shots in A groups and had zero issues. Love the optic and may buy another for my next G19. If you’re not a brand snob, try one out. I think they’re worth every penny.
