Just buy it - Olight Osight S 1x14-21mm Reflex Red Dot Sight

I was a little hesitant, not being familiar with the brand, but decided to pull the trigger on it anyway, and let me say that I am dang glad I did. Site picture is clear a the “dot” is clean and crisp. Got it zeroed without any fuss. All the extra screws and containers were a nice touch. Time will tell as far as durability. However, craftsmanship seems to be flawless, so I have high hopes now if I must have something to complain about would be I wish you were just a little bit smaller however, for being fully enclosed, I was still impressed by its size. Also, the idea of not dealing with batteries changing batteries is worth its weight in gold for the price. If all their products are as high-quality as this then O SIGHT has made me a customer for life…..
