Frequently asked questions
The HOLOSUN HE507C-GR X2 is designed primarily for full-sized handguns and is suitable for both competitive shooting and self-defense. It is a reflex sight that offers users fast target acquisition and an easy aiming process thanks to its 2 MOA dot and 32 MOA circle reticle.
The Shake-Awake feature on the HOLOSUN HE507C-GR X2 automatically activates the sight when it detects motion. When the sight is not moved for a set period, it goes into a sleep mode to conserve battery life. Upon movement, the sight instantly turns back on to the last brightness setting used.
The solar failsafe in the HOLOSUN HE507C-GR X2 allows the sight to remain powered in the absence of battery power, making use of ambient light to operate the reticle. This feature offers reliability and an extended operational life, ensuring that the sight remains functional in a variety of lighting conditions.
Yes, the HOLOSUN HE507C-GR X2 is described as parallax-free, meaning that the reticle will remain in place even as the user's eye position shifts. This helps in maintaining accuracy and precision because the point of aim is consistent regardless of eye position relative to the sight.

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.

OEM Holosun product, so good it came zeroed for my weapon straight out of the box. Shot quite a few rounds through it. Love the multi reticle system and the self adjustment. It’s perfectly functional, it fits great on my dagger and doesn’t weight more than any other dots I have.

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 .

This is a great sight for people who have a hard time with red dot sights. The green dot is alot easier to pick up in the sun light and in the dark. It only takes about two minutes to mount it. I now have three green dot I would recommend them to anyone looking to add a sight to there hand gun.

Works just as it should. The only issue is that the battery was dead on arrival but that was a simple fix. Fit is good. I like that you can select from 3 red dots.
