Really impressed me so far. For the price, the quality is outstanding, clear glass, crisp bright dot, long battery life, and solid construction. It holds zero and has been just as reliable as my Holosun or even Trijicon purchases, but without the hefty price tag. If you’re looking for a dependable optic without breaking the bank, this is a great choice.

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.

Upon receiving straight out of the box it is very good quality. Mounting it to my Taurus G3 toro was effortless. The micro optic sits flush with the sides of the pistol for a perfect fit. The red dot is crisp and glass very clear. Feels like a red dot worth 3x its cost. Once I get some rounds through it I’ll add an update.

Unboxing the micro red dot sight I was pretty impressed already.It has a look and feel of a quality built optic. I like the fact it doesn’t have white paint writing on either side. Just covert non reflective black. It mounted easy and comes with quite an assortment of screws for various applications. The red dot emitter is crisp and clear as is the glass. I’m very pleased with it so far. I have not range tested it yet but when I do I will repost if any of my opinions change. Great little optic for a very fair price.

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!

Great little dot for the price. Comes with a bunch of mounting screws. Mounted right to my CZ p09C nocturne. Will also work on my p365s and 43x but they already have other osights on them.

Quality, meets affordability, great ease of use, sight A+, battery easy on and out long lasting. For my use and money better than outrageously priced competition.
