Frequently asked questions
The Shake Awake feature of the Holosun Reflex Sight is designed for power conservation. If the unit has not moved for a certain period, this feature will put the sight into sleep mode. Once it senses motion, it immediately powers back up and is ready for use.
The 2 MOA (minutes of angle) dot in Holosun Reflex Sight is the spot size at 100 yards, meaning it covers 2 inches at that distance. On the other hand, the 32 MOA circle provides a larger field of view which can be beneficial during rapid target acquisition situations.
The difference between the red and green dot in the Holosun Reflex Sight is primarily a matter of personal preference. Some individuals find the green dot to be more visible in daylight. However, performance wise, both colours provide the same functionality.
Parallax-Free means that the dot in the Holosun Reflex Sight stays in alignment with the firearm, irrespective of the shooter's eye position. This provides a significant advantage in rapid target acquisition and shooting accuracy, especially in high-stress situations.

The HOLOSUN 507C X2 is the real deal. The shake-awake works instantly, the solar backup is clutch, and the reticle options (2 MOA dot or 32 MOA circle) make target acquisition stupid easy. The green dot is crisp, bright, and doesn’t wash out in sunlight. The aluminum housing feels tough enough to survive a small meteor strike, and once it’s zeroed, it stays zeroed. Parallax-free, super clear glass, and the battery basically lasts longer than most New Year’s resolutions. If you want a rock-solid optic that performs way above its price, this is it. Your handgun will feel upgraded the moment you mount it.

Great optic ! Their pic rail lights are awesome too . Glass is ruby coated and extremely clear. It's as fog proof as it gets , but I still use a little cat crap..adjustments are easy ,built like a tank and solar backup is a must have ! Well priced too and fits perfect no gaps and looks sweet on a Walther PDP-F frame...adds no felt weight . The best on the market .

So far I love the sight and it seems to be a great RDS which I wanted for hunting season for hogs and for under 350$ it’s a good deal. I went to my local gunsmith and looked at their stuff and asked for suggestions and this is what I ended up buying and it seems to hold zero pretty well. It took 2 adjustments to get it in the center of the paper and holding a decent group. It is as wide as my pistol so it looks as it should on my 10mm. The glass is super clear on it and even with astigmatism I found it easy to acquisition to the RDS because on my S&W M&P 2.0 I can co-witness the iron sights for 2 different ranges. I love the auto brightness but that’s just me, I seen some complain about it but I actually found it to be the right brightness for me like that vs always hunting for the “right” brightness for the ambient light. I actually used it inside and outside my home and it works well in artificial light for me but better in real sunlight of course. All in all I would buy from the seller that I did and found the sight to be in new condition even though the box was not sealed in plastic. Also the screws were in the same type of bag that the one guy is complaining about and saying it’s not factory when it obviously is (at some point the changed the bags they use). 5/5 stars for sure! Won’t be my last Holosun!

These green dots are bright! They are high grade quality with easy setup and adjusting. They are super easy to clean and see through. Compared to some other brands, I can afford these, and are a great value so you don’t pay too much. One thing to note, you need to use a green laser to zero them in. You won’t see red through this.

Can't go wrong with this green dot. It's very clear, my site speed has increased, and it seems to to be a great value for the money given its perfect quality. Sighting has never been easier. Wet easy to use. I will be buying more of their sites

First off, I had to return the first one I bought. It didn't work. This one came just days later. Easy to install and works as expected.

I've become a fan of holosun, but this sight missed the mark for me. I have several 510c sights and they work very well on my carbines and even shotguns. This i my first pistol red dot and its kid of a pain. The controls a very small and hard to use. I have a devil of a time turning the sight off and often have to hunt around to find the reticle. The Buttons are so close together i often have to use a tool or spent casings to press them. That being said, it is well made and hold zero even after nasty drop due to me fuddling around trying to turn the sight off.
