Unbeatable Value - Holosun 507C X2 Green

Updated 45 months ago

Good morning, everyone, this is John with gun.deals, and today we’re taking a look at perhaps one of the most popular pistol optics on the market currently, this specific model is the Holosun 507C x2 green version, though, again, Holosun optics in general are fairly ubiquitous on pistols nowadays just because they provide so much performance per dollar that it is very hard to beat.


Full disclosure on this optic, I paid about 220 dollars for it on a KillerDeal, which is another awesome thing about these optics is that they generally can be found for under 300 dollars, depending on which model you go for, and sometimes they can be found for around 200-dollar mark.

This one specifically, as I mentioned earlier, this is the 507 C x2 green version, so the 500 series, full size red dot with the multiple reticle options, so getting into that really quickly. I’m not a huge fan of the Holosun general reticles on the 500 series, I’d much rather have just like a six or an eight MOA dot, like you can find on the 400 series.

However, the reticle in the 500 series is, you have a two MOA dot and the 32 MOA outer circle and then you can cycle between one or the other or, of course, both of them at the same time, this is, of course, the green version.

Getting into the specs on the build itself, fortunately, these are made out of 7075 T6 aluminum, which is about twice to 2.5 times as strong as 6061, so in pistol optics where strength is paramount because they’re not necessarily the most durable things by design. I’d like to see 7075 and, of course, a thick hole like the 507C has. This is definitely not a small or lightweight pistol optic, though, again, it does air more on the side of durability.

In terms of controls we, of course, have a Plus and a Minus button for plus and minus things, you have 2 night vision settings and then 10 daylight settings. On the green version the battery life is still rated at 50 000 hours, now that’s as setting six, which is not really usable, usually with this optic I’m in full daylight, you’re gonna be towards the top end of the brightness levels, it does get more than bright enough for sure, but it’s more usable at the, you know, 10, 11, 12, somewhere in that range, for full daylight use, so you’re never really gonna be on setting six, unless you’re indoors or something like that.

Of course, we have our elevation and windage, which are slightly recessed into the body. Somewhat, unfortunately, they use a very small flat head for adjustment, so they can be a little bit obnoxious to adjust on the fly as it does require a very small tool to get in there and adjust them. Fortunately, on this optic, though, is very rare that it’s going to lose zero as these are very durable optics, so you shouldn’t be adjusting it all that much, it’s more of a set-and-forget style of thing.

The mounting platform for the 507C, this is an RMR platform, so anything that can take an RMR should be able to fit the 507C. This is direct mounted to this AimSurplus slide, which is, of course, cut for an RMR, and it fits very nice in here, it is a tight fit on the slide, so you have almost no movement forward and back. Unfortunately, there are no recoil bosses on the AimSurplus slide, so eventually those screws will probably snap or shear off and you will need to replace them to retain your optic to your slide.

Speaking of securing the optic to your slide, this uses basically an industry standard of two torx bolts that bolt directly into the slide itself, again, the only thing that this combination is missing is recoil bosses on the slide, which would provide an additional level of security and, of course, take some of the force off of your screws that are meant to just be clamping, not as necessarily recoil bosses.

These are torque to 22-inch pounds, I believe the recommended specs is like 18-inch pounds, but I usually just go just a touch above what they recommend and these are also blue loctited in place, so in theory, unless I get this gun very, very hot, they shouldn’t move whatsoever.

Last couple of things to mention on the body itself, on the right side of the optic body we have the side loading battery tray, which is a very nice feature, meaning that in the event that battery does die at some point in the future, you can change the battery without having to adjust your zero like on certain RMRs and other optics that use a bottom loading battery.

It is a 1632, which is, again, not quite as powerful as a 2032, doesn’t have quite as much juice in there, but, again, they are still claiming a 50 000 hours battery life, so it doesn’t seem to hamper performance too much.

On top of that, this also comes with Holosun’s solar failsafe technology, which is not a charging unit, so it does not charge the battery when it’s installed, all this does is provide, again, a failsafe, should your battery die, go dead, what have you and you are exposed to enough ambient light, the sun or what have you, it will be able to power the reticle and it does work, it’s not necessarily a gimmicky feature as it does work.

For me personally, on these sort of red dots, or green dots in this case, that have exceptionally long battery life to begin with and then that is, of course, paired with Holosun’s auto-ON/auto-OFF technology, which will, again, extend your battery life even further because it’s only on when it senses motion and then after a few minutes it will automatically turn off. The solar failsafe is perhaps a little bit redundant, not that that is a bad thing to have on your optic, is, again, just another power source in case that battery goes dead.

Admittedly, that is a ton of features and options in an optic this small and lightweight, coming in at a whopping 1.5 ounces and it basically has every trick Holosun could throw at it.

Getting into the glass itself because, of course, you are gonna be using this, it is a fairly large window, it’s not the largest window on the market, you have SROs and some other more specialized optics that have really large windows designed for target, competition, so on and so forth, but the 507C is certainly no slouch in that regard, you can definitely get your eyes behind it in a variety, in a large range of motion, so it is easy to find the dot, very easy to pick up, especially if it’s something that you practice with. It is something that is not a problem, I can still do it on smaller optics with smaller windows, but, again, having a bigger window is just a nice feature to have.

Getting into the glass quality itself, it does definitely have a very noticeable blue notch filter that is common on most Holosun optics, however, the glass itself is crisp, it is clear, it is nice, it does have a very, very noticeable warping, in fact, if you just move it around you can definitely see that there is one a good level of magnification going on as like 1.05, 1.1, somewhere in that range, as well as a little bit of warping, especially around the edges of the glass.

That is a trade-off because the glass in the optic is very thick, there are definitely optics that are pistol optics that provide less distortion, less magnification, they have a little bit more natural looking of an image, if you will, however, they’re not gonna have the same level of durability, which Holosun has definitely gone with a more durable design, it definitely has a very thick optic shroud that’s going to take a lot of that impact, should you happen to drop it, and you can watch very good drop test videos by Sage Dynamics and other channels, showing that these are indeed durable, tough optics that can take a beating in a variety of situations and continue to work.

So, that is the trade-off that you’re gonna get in terms of glass quality and the actual image that you’re getting through it, it’s not that it’s bad or unusable, it’s maybe just a step below, some more, again, competition or target focused dots that are gonna sacrifice that durability to give a little bit cleaner of an image.

The reticle in this model, again, as I mentioned a little bit earlier, is the variety pack reticle, if you will, you have the 2 MOA center dot, 32 MOA outer ring or you can do a combination of one the other or, of course, both.

Me personally, I prefer a simple 6 MOA dot, 8 MOA dot, 3 MOA dot even, just something very simple, quick to acquire, that sort of thing.

In this optic, the way I would usually run it, is with just the 2 MOA dot about a setting above what I needed, so I would bloom out a little bit and give me just a fast sight acquisition, but not necessarily be imprecise, so a 2 MOA dot is perfectly fine.

The 32 MOA outer circle I’m not the fan of on this optic because at medium distances, say between 15 and 50 yards it can actually obscure some of the target, especially depending on target size, so in certain circumstances it might help you pick it up a little bit faster, when you’re shooting very quickly it kind of looks like a big green blur that you’re just putting on the target, which, again, works well for speed shooting, but if you try and slow down and do a little bit more precise shooting, that 32 MOA outer circle, especially if it’s, you now, a setting above where it needs to be, can kind of bloom out a little bit and start blocking large portions of your target.

What I would have preferred on this honestly is instead of a 32 MOA outer circle have a much larger 65 MOA circle because that would still give you a ton of space around the center dot where you could still use it as fast acquisition up close, say like five yards, just put the circle on the target, pull the trigger, and then, of course, at extended distances or intermediate distances, really it would still give you enough space around the dot that is not obscuring your target.

Personally for me, I’d rather either have just a dot or something like the ACSS Vulcan reticle where it has the chevron, which works well for precision and for fast acquisition, but then also, especially if you’re someone who does not shoot with a dot very often, also kind of guides your eye to the center and will help you line up that dot every time, shooting from odd positions, again, learning to shoot with a red dot in general, especially if you’re going from iron sights.

Learning how to shoot with a red dot, it can be slightly different and slightly difficult in certain circumstances to just instantly pick up the dot every time, and even something myself, who does shoot with a dot quite often. It is something that I would like to see, it’s not necessarily needed and, again, if you’re somebody who needs that sort of help thinks it would be faster, so on and so forth, that is something worth looking into.

Currently on the market there’s really not too many companies making durable style optics like this that are also in this price point of, again, somewhere between two and 300 dollars, depending on what model you’re going for. They’re really kind of the only game in town, I know that there are a few more coming out like Swampfox just released their Kraken optic, which I might have to take a look at very soon, on top of that, you also have Primary Arms coming out with their new red dot, which I’ve seen and heard mixed things on, but overall, currently Holosun has a very good track record with their pistol optics, they have a ton of different options and closed options, titanium options, all of the different features you could possibly want and, again, at affordable price point.

So, do I recommend Holosun pistol optics?

Absolutely!

If you need a pistol optic and you’re in that not quite super budget range, but you want to save a little bit more of money over like an RMR or Acro or something like that where you’re gonna be spending four, five, six, seven hundred dollars to acquire some of these other red dots, then I would absolutely recommend looking at Holosun. The performance to dollar is very, very hard to beat.
