HOLOSUN HE507C-GR X2 / HS507C X2 2 MOA Dot & 32 MOA Circle Open Reflex Pistol Sight - Durable Shake-Awake Solar Failsafe Parallax-Free Aluminum Sight for Full-Sized Handguns - Green & Red Dot Options

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.

Sturdy red dot, the glass is clear and the red dot is bright with good adjustments.It has shake awake and a solar back up which were important features for me. So far very pleased with the quality. It comes with all the screws you will need to attach it

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!

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 .

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.

Very easy to mount and zero. Great product 💯

Meets product description. Functions flawlessly. Still lights up after one year.

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.
