Color: Green Dot
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.

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.

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 am very pleased with this sight. To be honest, I bought a PDP that offered a free sight, but the wait is so long, I decided to purchase an inexpensive sight in the interim. I have had it to the range three times now and have about 500 rounds on it. This sight's performance is exceptional. The window is larger than my Holosun EPS, and does not look clunky on my pistol. The multi dot reticule is bright, well defined, and the accuracy is dead on. It holds zero, has a 50-to-60-thousand-hour battery life, and a side loading battery tray. The screw package it comes with is the most extensive one I've seen. I am pretty sure that when my free optic arrives, I will be sticking to this O sight, priced at less than half the MSR.

This is my second Osight optic and they are fantastic, nice fit, easy installation with the screws provided, good quality. The dot is clean and sharp, plenty of brightness levels. This optic already survived a hard fall on concrete at the range, the screws holding the plate to the pistol got stripped and the optic went up in the air flying in the middle of shooting, not a scratch, glass perfect.

Pros: Install was easy. Optic itself is really nice. Good window size. Cons: Battery life. I left it “always on” with a brighter setting with dot+circle. It didn’t even last 450 hours (19 days). I’m not sure how that compares to other brands but I feel like that was a little quick. Changing to shake-awake to see how that does.
