Can't say much except what others have said. Only wish I'd have grabbed a couple when I first saw them at like $140-$150 I think. Steadily saw the price go up like $10 every week as they got more popular. I saw it hit $180 with a coupon that brought it down to the previous weeks price and jumped on it. Now $200 as of this review and I'm sure it will go higher. I'm not really a fan of their flashlights but, this is an impressive little piece. Super small footprint and super low deck, despite being a side loading battery that sits parallel with the slide. Impressive. Most optics that sit this low would have one of those goofy perpendicular battery boxes that sits on the side (or even the top...) and sticks out like a thick quarter in your visual field... or worse yet, a bottom loading battery. But yeah, nice flush fit, side battery tray with screw cover and I really like the uniform width. Some optics have a shape that kind of starts one dimension and then flares out up front, which is cool sometimes but I feel like with an optic really designed for a micro compact carry gun, it should be as low pro as possible. I'm sure we're just getting started with tech like this and these will be antiquated within 5 years but maybe not... the RMR is still around and hasn't changed much in like 15 years and people still buy that bulbous expensive bottom loader despite all the other great options out there. I am a huge fan of the multi-reticle and I would definitely recommend it to ANY shooter because you can change it to fit your style but I would especially recommend it to shooters who are new to shooting red dots. I'm fairly new to red dots myself and having that circle dot really helped me get used to drawing and snapping in to the sight picture fast like it should be instead of spending a lot of time looking for the dot like most RDS newbies do. Of course the better fundamental is to try and pretend you have no dot and just punch out normally, trying to pick up your irons but it's not quite as easy as it sounds. Having that option of a larger reticle footprint that's super easy to pick up but still have great accuracy potential as opposed to just a huge solid dot is awesome. Then as you get more used to shooting with a RDS, you could transition to just a dot if that ends up being better for you, or you might just find you like the circle dot. I am actually finding myself enjoying just the big ring with no dot right now for close up tactical type shooting. My eyes seem to be able to tell my brain and body to shoot pretty accurately with it and there's no obstruction from the center dot and super easy and fast to pick up. I always liked a really wide notch rear iron with a really skinny front so I got lots of light and visual coming through. I actually shoot that style more accurately than the the traditional "target" sight setup which is to basically have almost no light coming through your front and rear alignment. I guess my brain is kinda backwards. I also prefer the red color over the new hotness that is the green, unless it's actually a projected laser dot sight ,but that's really only because of the fact that you can actually see a green laser in the daytime and most of the red ones are nearly impossible. Anyhoo... that got a little wordy. Oh well. Yeah, it's a good little sight, very clear, co-witness on my hellcat pro shows probably close to 75% of the sights from the top edge and they don't come with super tall sights so that's pretty impressive. I still haven't really decided if I wanna EDC with a RDS but this is definitely the one I would choose if I do. I carry appendix style pretty low pro and I dont wear undershirts so I would definitely want it enclosed but if you're more of an OWB carrier it wouldn't matter as much. I have a bunch of different open reflex RDS but this my first closed one, and I gotta say, I'm sold. They should pretty much all be enclosed like this I think. Maybe even sold with replacement windows somehow...IDK. BTW, if you're not hip to all the stupid acronyms, don't worry about it. Here's a translation matrix of a few of them: 1. EDC= everyday carry. The gun and or other weapon or defense tools you carry everyday. 2. RDS= Red dot sight. Also sometimes called MRDS= miniature red dot sight which are the size usually found mounted to pistol slides. Some also call these RMR's as a blanket label but RMR refers specifically to the offering from the trijicon brand that was basically the first one that anyone mounted to a pistol with a reciprocal slide. It stands for "ruggedized miniature reflex" sight. Reflex is the type of sight that basically has a reticle of light projected from a small emitter on the deck onto the lens. 3. OWB= refers to holster/carry position, "on (or sometimes "outside"the) waste band" 4. IWB= inside waste band. This can be many positions around the circumference of your waste and is preferable for more discreet concealed carry. 5. AIWB= this term specifically describes the "appendix" style of in waste band carry which positions the gun low, just above the belt line and either just left or just right of the buckle. Usually whichever side your dominant hand is. There's tons more but that can get you started. I hope this can help someone.

This thing holds zero like a champ. It’s well-made, solid, and the price is unbeatable for what you get. The reticles are steady and bright. I have it on my Hellcat Pro as my daily carry, and I absolutely love it.

Mounted it on my S&W M&P 9L. I'm trying to replace all my bottom battery red dots as funds permit and the batteries need replacement, so I'm looking for some thing solid and suitable for heavily used range guns at an nice price, but don't need life and death reliability -- my carry guns wear Trijicon dual illumination optics (fiber optic and tritium) as I'm of an age where I just won't trust my life to a battery. So far I love this thing, packaging is outstanding and bordering on overkill especially for the price of the product. Great assortment of mounting screws with a spare of each, the replacement screws for the battery compartment is particularly welcome, since after the first 200 rounds it had backed out noticeably. I tightened it and it has not budged 300 rounds later, I was paying attention to it as other reviews said it was prone to backing out and be easily lost. Was easy to mount, zeroed it with a 9mm cartridge laser boresighter and it was on a 3" circle at 10 yards, minor tweak and I've not touched it since. Have run a bit over 500 rounds through it beating up steel plates in three outings so far. I like the circle-dot best, very fast for the 8" plates and dot is tight enough for the 3" triangles. My only very minor complaint is it is hard to push and hold both buttons to turn it off. Not a fan of "shake awake" as it means the sight in on during my trips to and from the range, increasing my chance of a dead battery when I arrive (I have a spare battery in my range bag, but I'm going there to shoot, not change batteries)). But third time out I had a lot less trouble getting it to turn off, so this might all be on me. I expect I'll be getting another in a few months when my next bottom battery sight needs changing.

*Multiple purchased and loving it. Enclosed emitter so easy to keep clean and clear* This is fantastic! Like a game cheat code for your pistol! Simply put the dot on the target and squeeze the trigger. LOVE the 2MOA dot only--32MOA circle only--2MOA dot w/ 32MOA circle options for this optic. I use different ones for different setups/applications. Like having 3 in 1 optics. It is a red dot. I prefer red dots to greens personally. Clear and crisp view window. Co-witnesses very well with SF Echelon, FN Reflex XL ect that have the direct to frame RMSc mounting systems or ones with suppressor ready sights. Compare to Holosun. (<---it's what I did) I believe it compares very well. I like the SE's side mounted battery. Not a fan of the charger cover models. Mounted very easy. I am mechanically inclined but have never mounted anything on a pistol before and had no issues. I do recommend using a torque screwdriver to get the proper inch-lbs on the mounting screws as well as using loctite blue. I used a bore sight laser to zero it and was spot on the first time at the range with no drift over time. Very sturdy and durable. I used the optic to work the slide with no issues. The price point Osight is coming in with and the sale right now makes this a no brainer. **Update** This is now the 3rd one of these I have purchased. The original for my SF Echelon 4.5f , the next for my FN Reflex XL, and now a final one for my FN 502. These are firmly holding zero after 500+ rounds even after using them to cycle the action and are still bright and clear. They are every bit as good as similar models that are literally double the price. Will update if anything changes but feeling REALLY good about these purchases. These MRD optics are a blessing for someone like me that would normally have to wear reading glasses to use the iron sights.

## **Impressive Performance – Best Value Enclosed Optic** I’ve used a lot of different sights over the years, and I have to say, this enclosed micro dot from Olight is a fantastic value. If you’re looking for an enclosed emitter without the massive price tag of some other brands, this is a serious contender. * **Clear Glass & Reticle:** The glass is incredibly clear with minimal distortion. The dot is crisp and easy to pick up quickly, making target acquisition feel natural and fast. * **Rock-Solid Function:** It functions perfectly. The motion-activation is responsive, so it’s always ready when I draw, and it has held its zero perfectly through several hundred rounds. * **User-Friendly Adjustments:** Zeroing it was a breeze. The windage and elevation adjustments are tactile and easy to dial in, which isn't always the case with micro dots in this price range. * **Enclosed Design:** Having the emitter fully protected gives a lot of peace of mind. You don't have to worry about dust, lint, or rain blocking your dot at the worst possible time. **Final Verdict:** This stands up surprisingly well against the more expensive optics I’ve used. It’s reliable, easy to live with, and looks great on the slide. If you want high-end performance on a budget, you won't be disappointed with this one. Highly recommended!

As the title says I’m a beginner, just got into the CCW world. After doing some research I kept running into OSIGHT and their affordable yet good optics. I think being a beginner I was ok with going with OSIGHT - ignorance is bliss - and it was a great choice. I went with the green dot thinking it would stand out more in the daylight. I also ordered a torque screwdriver as well as a laser bore sight, as I know this willl not be the last optic I’ll buy. Installation was easy , it came with multiple screws, no additional plate needed. It fit right on my Glock 43x. After taking it to the range it has held ZERO. The glass is crisp and clear , the green dot light is adjustable and stands out even during sunny days. Only issue I may have is sometimes the buttons are hard to press to make my needed adjustments but besides that it’s a great product. I just got a CZ P-10f optics ready and OSIGHT is on the top of my list when it’s time to get an optic.

This sight fit my P365 nicely. The install process was easy and the included screws had blue thread locker already in place. The instructions are clear and simple, and torque specs are provided. Changing modes and brightness are extremely easy. Zeroing is simple and the method seems to hold true. The small dot size is perfect. The only flaw I have seen is that battery door flew out within the first 50 rounds at the range. Fortunately I found the screw on the bench and was able to reinstall it. After making sure the door was about as tight as such a small screw can handle it seems to be staying in place. In any case I would keep the included tool and included spare battery screws with you while shooting.

This optic really does stack up to other enclosed emitter options on the market as far as performance goes. It's great for compact carry due to its low profile, the window is plenty big to give the user an great objective view. The optic housing feels sturdy. The glass feels sturdy as well. The reticle is on par with every popular brand including Holosun and Vortex. The battery can be changed without removing the optic which is a huge advantage. Made out of lightweight aluminum and is compatible with the RMSc footprint.
