HOLOSUN Exclusive 507 Red Dot Reflex Sight, 1 MOA, Green Reticle, ACSS

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.

I love these - have them on 2 pistols and 3 rifles. Yes, they’re a bit more expensive than the cheapest options, but I think they give top tier performance at what I’d call a midrange price point. They’re very durable, have never given me any trouble, and that ACSS Vulcan reticle with the circle makes sight acquisition super fast (especially helpful for my 2 scoped rifles, where I have them mounted 45 degree canted, and rotating off the scope to the dot quickly makes acquisition with just a plain dot especially challenging - but with the large outer circle, it’s immediately obvious and intuitive which way to move the gun to find the dot). And don’t let the seemingly high MOA on the center chevron fool you into thinking it’s not very accurate - that’s the spec for the entire chevron - the very upper tip of the chevron is just as fine/accurate as most other red dots - seems about 1 MOA, but don’t quote me on that). Having the battery access along the side is a must have as it doesn’t require unmounting, and the solar panel backup saved my range day one time when I forgot to bring along a spare battery. The shake awake is also a must have, and this one works great. Also, I love the fact that this dot can mount so low relative to the bore sight. I’d recommend spending the extra $ for the green dot since it is noticeably easier to see on a sunny day.

Started on a Glock 19 and absolutely loved it. If you have astigmatism this is a must have. Circle is fine but gets distracting over time. If you are shooting in awkward positions though it helps out a bunch. This will now go on a rifle piggy back mount and will work perfectly as it is a lot more accurate with the Acss reticle

The ACSS vulcan chevron on this is superior to a basic red dot in that it allows for quicker acquisition and pinpoint accuracy using the very top of the chevron. I have the HS 507C X2 (not ACSS version) also, it has the basic red dot presentation. I shoot better with the vulcan sight. I also have the HS 507K on a micro pistol. It is a great red dot, but doesn't have the vulcan chevron. The red dot purists seem to not like the chevron I hear, and I understand that as the basic dot may not obscure as much -- but in using the chevron I've found it enhances target acquisition, especially in follow up shots. The large outside circle is also very helpful if you need it, but I generally never see it except when moving to shoot. Then it offers a quick reminder and aid to get chevron on target. If you hold gun at normal arm's length grip, you'll hardly ever see the big circle -- and if you do, it's helpful and not obtrusive. The chevron also gives you basic holdover pictures if you want to shoot at longer distances. For me, after shooting basic red dots for a couple years, this vulcan reticle is superior. Doubt I'll go back to basic red dot, but never say never..........ha.

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!!

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.

Very nice . High quality optic.

Usually I try to rate things fairly and add cons this has no cons it's the T1000 of weapon mounted optics. it's amazing it's extremely clear and I love the outer ring reticle you get so used to it that you don't even start to notice it when you're using it. because you're always right back on point I love every single feature of this device, The fact that it has an auto shut off, The fact that it has an auto dim and brightness, and it has the solar, which I don't know if it's working however it's been months and months and months of use. and this thing continues to keep going exactly just fine I also checked with the manufacturer this is One of their authorized dealers so there's not going to be any chance of buying a fake product. I would recommend if you're going to get this. buy some q-tips as well throw them in your truck or car that way you can easily clean the inside of the glass, they come in handy for that.originally I posted a whole different review specifically for this product but Amazon didn't let me post it because I showed pictures of my handgun it's crazy thinking that they sell a strictly weapon mounted product yet they don't allow images of something that is considered completely acceptable in society's eyes either way I digress 😆 I do really recommend this product it does exactly what it's intended to do and the green reticle is much easier to see than red you can see this on YouTube I'm trying to think of anything else to add but really I think I covered everything exceptional product.
