Features
- 6 MOA Dot:A 6-MOA dot fosters quicker target acquisition and better visibility, making it ideal in high-stress situations. A larger dot adds consistency to presentation and target alignment.
- Side-Loading Battery:Effortless battery replacement without removing the optic ensures hassle-free re-zeroing. A premium-grade battery features easy accessibility while maintaining steady performance.
- RMSc Footprint:Designed for RMSc Footprint-cut, optics-ready slides. Non-RMSc slides require an adapter plate (not included). Please verify compatibility before purchase.
- Motion Sensor Function:A motion sensor activates the optic at the slightest motion, and powers down after 3 minutes of inactivity to conserve battery.
- Low Power Indication:If battery voltage drops below 2.2V, the reticle will quickly triple-flash once per minute to recommend an imminent battery replacement.

Have this mounted on a Canik MC9 prime, and it is a perfect and snug fit with the included screws. The buttons can be a little hard to press if you're wearing gloves, but otherwise they function quite well and have a nice tactile "bump" when you depress them. The glass is clear and easy to clean. The laser itself handles all light levels with ease; it gets brighter than the sun at max level, making it perfect for daytime training, while it offers multiple night-modes that I've found very useful in a variety of circumstances and training conditions. Additionally, the added circle and circle-dot reticles you can cycle to are clear and crisp, and I've had a lot of success with the circle dot (though I swear the dot itself sits a little below what should be the center...others say I'm crazy but idk) at longer ranges. It has survived 3 accidental drops on concrete and 3k rounds with no issues other than needing to reapply loktite a few days after first mounting it. I have not noticed any significant zero drift after reapplying the locktite and re-zeroing the pistol - thousands of rounds of various types with no issue. Battery life is outstanding so far, though they make it even easier to swap the battery out so no worries there. For the price, this should jump to the top of the list for anyone looking for an RMSc pattern pistol optic. A homerun for OSIght!

Very pleased so far. Good build quality at a very competitive price. Prefer the large 6 MOA dot to smaller dots, much easier to pick up and and see. Shake-awake (motion-sensing) works well and should significantly extend the battery life. Easy to mount (make sure to use blue threadlocker on the mounting screws). Easy to adjust for elevation and windage. Side-mounted battery is a big plus. Some designs use a bottom-mounted battery, requiring removal, battery replacement, re-installation and re-zeroing just to change the battery.

For the price, this is an excellent dot! Easy to use comes with all the necessary accessories, has been holding zero after several range trips. The lens looks good and the quality overall seems very high. I only wish it came with more features, but at this price it’s perfect.

I’m going to start out giving this optic a five star review. The 6MOA dot is perfect. The function seem to work perfectly and mounted to my Taurus TX 22 Toro perfectly. I will be using this system for USPSA rimfire matches, so it will get a lot of reps. Some reasons for this initial score are the included mounting screws. They are pre treaded with thread locker and include two of the most common metric and English thread sizes, and to add more versatility each size comes in two lengths, with three screws of each type. This is more than needed for RMSc mounts, nice touch Osight! Also the screws are packaged in very convenient and labeled plastic boxes. Over the top, but appreciated. Ohh almost forgot there are two spare battery compartment screws included, and a battery pre installed but not activated until the plastic insulator is removed. Now for my testing, it survived a 1M drop test while mounted to my pistol onto a thinly covered concrete floor. Impressive. Finally I purchased with my own money during the introduction sale. Thank you Osight. Out of the park. Update: I Shot a steel challenge this weekend. 8 stages with five strings per stage, over 200 rounds fired, very fast. I used the optic in bright sunlight, and didn’t have to run it on its brightest setting. Shake awake worked perfectly the optic was always ready to go. I found the dot easy to track once acquired. I shot the “Smoke and Hope” stage at a personal best of 13.68 seconds with my best string being 3.17 seconds for five trargets. This is the perfect companion for my new TORO TX22.

Early review, amazing optic. Decided on the six MOA for easy target acquisition. Shake awake is beautiful side loading battery is fantastic. Zero in with a bore laser and was pretty close out of the box. It feels quality and the adjustable brightness is great with the brightness being pretty bright. It’s the perfect size to conceal carry. Will update after I go to the range to see how it holds zero. But for the price fantastic quality.

The media could not be loaded. Unboxing video and first impressions. The build quality seems very solid and has a nice clean sleek look to it. Packaging of the product by the manufacturer is 10/10 awesome. The item functions fantastic and seems like it will stand the test of time. Shake awake feature works great and 6MOA dot is a great size. Side load battery compartment is the only way to go! It was super easy to install with the RMSC footprint. It fit directly and very snug onto my hellcat (had to tap it on with rubber mallet). The only reason or 4 stars instead of 5 is that I have not been able to test it extensively with many many rounds and recoil. That and the fact that this is a relatively new item with a very short track record compared to some others, is why I gave it 4 stars. If this item measures up (the way I think it will), we will have a new competitor among the mid level red dots on the market. If OSIGHT backs up their products and keeps them at this affordable price point, they COULD end up taking over the market!

So far this sight has been really good, I have about 350 rounds through it and it still holding zero, very easy to install, make accuracy adjustments, and battery access. Comes with all the screws and tools needed as well! Cowitness on the shield plus is perfect as well

This is the perfect sight for a TX22 and Canik METE MC9, super easy to install, perfect fit on any RMSC foot print, so far I've got 1000rds on a TX22 that I have nick named "The baby A10" for no particular reason and about 300ish on my CANIK I so sadly lost in a boating accident in Alaska
