HS507C-X2

I have never had a problem with performance, clarity or durability from any of their products. Mounted on everything from 12ga to 22lr, pistol, rifles..zero problems. Its a perfect optic for east coast deer hunting with sub 200m distances on a lever gun or 300blk/450/x39 SBR. The 2moa dot allows fine aiming without the dot covering 90% of your target at 100m and the circle allows "eyeballometer" windage and elevation adjustments.

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.

Great sight. Looks good and the quality feels great. The packaging is very nice and had it installed in minutes. The green reticle is very bright and has plenty of adjustment.

Legit product, mounted in my echelon and took it to the range the next day and it the 507c worked flawlessly

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!

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

Overall it's a good sight but has a few minor issues. The reticle is well focused, very clear, lacks any streaking unless run super bright in dim light and it can get bright enough even against snow on a sunny day. I was unable to get a good picture of the reticle, so what you see in the pics I took does not reflect how that aspect looks. The option of 3 different reticles is also very welcome. The auto-brightness feature is fast and works as intended, but just like other sights with this feature, it always seems 1 or 2 settings too dim for my preference. Manual mode works fine and the buttons are tactile. Overall build quality seems excellent and mounting it was easy. The turrets are tactile and retain zero once set. I didn't do a box test but it tracked as expected when zeroing. The auto on/off feature works flawlessly and it turns on with the slightest touch. There are a few downsides, the biggest being it takes a lot of practice to quickly pick up the dot. The 32 MOA ring makes it easier, but a 100 MOA ring or something like that would be far better. The other 2 downsides are related to the glass. The glass has a very clear greenish-blue hue to it. This doesn't interfere under normal lighting conditions, but is clearly visible (see pic). The glass itself is very clear at least, just has that tint. The other problem is there is some optical distortion if not viewing the sight dead on. Once again, this doesn't hurt anything given that it's a pistol red dot and so point of impact doesn't change, but I can see it being distracting for some people. Overall, I think this is well worth the money and it functions great so far (about 1000 rounds of 22LR). I recommend it, but there is room for improvement too.

Without a doubt, this product is awesome. Easy to install and very accurate. I would purchase again
