HS507C-X2 / HE507C-X2 Pistol Red/Green Dot Sight - ACSS Vulcan Reticle

Great Optic, well worth the price! Have two of these, in on a semi-auto pistol and one as an offset sight on a 5.56 rifle. Awesome clarity and reticle has multiple settings. The buttons are a bit small, but that's the trade of for the small footprint. Highly recommended!

This Holosun fit perfectly and performed flawlessly

Very pleased with this red dot. Fits perfectly on a Canik Rival 02 adapter plate for the RMR footprint. Sighted in with laser cartridge, had to raise it about 20 clicks, but once at the range, Took 3 sets of 3 shots to have it in the bulls eye at 10 yards, and at 25 yrds. Noticing tighter groups during both dry fire laser practice. and at the range live firing, especially when doing my shifting target routines. The chevron for me really does help for quicker pickup and the 20mm circle is a great addition to help get the chevron where you need it quickly. The only down side for me is it is a bit dim in very low light and if you do use a light, it will wash out the chevron. It would be AWESOME if there was a front facing light pickup so that if/when using a light for low/no light conditions it would auto adjust the chevron brightness. Great product and glad spent the extra!!

Brilliant optic. Easy to navigate. Good selection of reticule options.

Absolutely Excellent. I have many other green/red dot sights. Unfortunately, I have an astigmatism so they all look to me as a blurry dot. However, for some reason that I don't know, this green Holosun with the ACSS Vulcan reticle is perfectly clear outside and has just a slight, dim, second image offset to the left. This second image does not prevent me from being able to clearly see the reticle.

TL;DR: Solid build, great materials, clear lens, bright emitters, fantastic reticle. Add secondary power option (so you're never REALLY out of juice), and a cheater ring to help acquire targets faster and you have a winner. Pros: + Made to take a beating + Dual power options (battery + solar) + Really bright emitters for easy day use + Cheater ring super helps reticle acquisition and faster on target Cons: - Chevron reticle can be polarizing and may get some getting used to - Turning off the optic requires two hands (you have to press two buttons at the same time and not easily doable with one hand) - Settings can take a little getting used to I'm super picky about optics, mainly because budget is always a factor but I love me some bells and whistles. I did my research on this sight and finally pulled the trigger—and boy does it not disappoint. I went with the HS507C-X2 Green Dot with the ACSS Vulcan Reticle and right out of the box this thing kind of screams "low key awesome". The controls are easy to manipulate (both buttons are on the left side), there's a battery port on the side and not the bottom, so you don't HAVE to remove the optic to change out the battery. Speaking of battery, did I mention that its got a solar panel across the top? There's also wake mode that is pretty responsive; in testing the optic was always on and ready when I picked it up, and after ~5mins of inactivity it powered down. I haven't tested it in a holster where there's constant movement, but if you're pulling this out of safe or a lockbox, it'll be ready when you are (don't forget to turn down the brightness for low-light encounters!). The chevron reticle takes a little getting used to, but once you've gotten familiar with it, its like an arrow that points to the target. The cheater ring is also SUPER helpful for reticle acquisition. I get that you're supposed to not hunt for the dot by having good training and muscle memory, but it doesn't hurt to have visual help to get on point. This isn't the cheapest of optics, but value-wise it far surpasses others I've used and researched. Time will tell how well it holds up to extended duty usage, but for now after 1k rounds its solid and haven't lost zero.

The optical fits well on my Glock 19 gen 5 rmr cut slide. It is very easy to operate and works well. The adjustable brightness is great and aids in its accuracy. The only issue I had was out of the box the battery that was provided was drained and would not charge with the solar power strip. The battery must work or the optic will not power on.

Great product with fast delivery and easy installation.
