In this modern world, we have a wide variety of options for every purchase we make. Whether it’s choosing what brand or type of water to buy or choosing between new optical sights, it seems like we have to make too many choices!
These choices exist because everybody has different tastes. The products that work best for you might not be the option of choice for your friends, family, or neighbors.
One of these choices is between the Holosun 507c, the Holoson 510c, and the Holosun 407c. All of these models might come from Holosun and look superficially similar, but they have vastly different functionalities that may make you prefer one over the other!
All of these Holosun optical sights are excellent models in their own right, but let’s see how they stack up against each other. Read on to learn more!
How They Compare to Each Other- How Different And How Similar
As Holosun optical sights, the 507c, 510c, and 407c will have similarities between the three of them. However, they will also have a similar amount of differences, if not more.
All three of these Holosun models are open-reflect optical sights. This term refers to the fact that they utilize a single lens for optimal visibility. This single lens sits at the front of the scope in all three models.
Additionally, all three Holosun models on this list are reflex sights. None of them are magnified, but as reflex sights, they allow you to shoot with both eyes open without a challenge.
One final similarity is that the 507c, 510c, and 407c are all red dot sights. Despite the name, not all of them utilize the color red in their construction- the name solely refers to their mechanism of using a single red dot as a rangefinder and target.
Now that we’ve covered all of their similarities, let’s move on to their differences. Beyond their physical shape and overall purpose, you’ll find that they have more differences than similarities!
HOLOSUN HS507C-X2 Multi Reticle Red Dot Sight
The HOLOSUN HS507C-X2 Multi Reticle Red Dot Sight, also known simply as the Holosun 507c, is one of the leading models in red dot sights.
With a durable titanium casing, the Holosun 507C can withstand the most severe environments. You’d be hard-pressed to damage this reflex sight with any regular force!
Additionally, with trademarked Shake Awake™ technology, you don’t need to press the power button on your Holosun 507c to activate it. Your red dot sight can turn on with a simple motion!
This same Shake Awake™ technology allows you to turn your sight off as easily as you turned it on. When it detects no activity, the Holosun 507c will turn back off.
Holosun designed this device for use with pistols, making it ideal for people who prefer using a sidearm to a larger firearm. However, the 507c is not the first in its line- and it’s probably not the last, either.
New Changes And Adjustments
Newer models in the 507c line feature improvements to its button design and the signature Lock Mode. When activated, the lock mode will set all of its buttons in place to prevent any change in your settings, whether accidental or by meddling with friends.
Additionally, Holosun placed the buttons on these devices far lower to further reduce the risk of accidentally adjusting your settings.
- Features two improvements in its Lock Mode and button design
- When you activate the 507c lock mode, the buttons get locked to prevent any change in the setting, and the redesigned buttons are placed lower so they won’t get in the way
Battery And Lifespan
Much like other red dot sights, the Holosun 507c runs on batteries. However, that’s not all; Holosun has added a miniature solar panel to this reflex sight to keep it running during poor conditions.
However, with an estimated battery life of over 50,000 hours, the odds are incredibly low that you’ll have to resort to using the solar panel. It’s nice to have in case your batteries corrode, but it shouldn’t be your first line of defense.
Holosun refers to this miniature solar panel as “Solar Panel Failsafe™ technology,” meaning that it's there to operate your red dot sight if the rest of your power- including your batteries- goes down.
With the environmental light energy in your surroundings, the Solar Panel Failsafe™ technology will keep your reticle illuminated even when you take the batteries out.
However, the Holosun 507c doesn’t just use light to power itself.
This reflex sight features a light sensor that will automatically alter your reticle’s brightness depending on the surrounding light levels.
This light sensor allows you to cycle through 12 available brightness settings to optimize visibility in any lighting scenario.
With a multi-reticle system, also known as an MRS, you can utilize your optic whenever necessary- or whenever you only need a certain reticle.
The multi-reticle system allows you to turn particular parts of your reticle on and off to best suit your needs and preferences. For example, you can adjust your 2 MOA dot or 32 MOA circles.
The lens of the Holosun 507c also features multiple coatings to minimize glare and impart some water resistance.
Additionally, with super LED visibility and night vision, the 507c is optimal for shooting in any condition or light level, day or night.
Holosun HS510C 2 MOA Dot Open Reflex Circle Dot Red Dot Sight
The 507c’s slightly larger cousin is the Holosun 510c. Holosun designed these sights for use with rifles or carbines, rather than the pistol applications of 507c.
The 510c also features Holosun’s trademarked Shake Awake™ feature.
With an aluminum and titanium hood, the Holosun 510c is notably large and durable. This reflex sight can certainly take a beating.
Battery Power And Lifespan
Much like the 507c, the Holosun 510c features a battery life of up to 50,000 hours. However, it only features battery power. The solar panel of the 507c is notably missing on the 510c.
The first thing you will notice about your Holosun 510c is the size of its window. In terms of relative size, the 510c’s window is notably larger than those of the 507c and 407c.
With the same reflective glass as the 507c, you can use your 510c without worrying about water or glare messing with your visibility.
The 510c doesn’t feature the MRS system of the 507c, but it does come with 2 MOA dots and a 65 MOA ring. You can customize these into any combination to your liking.
Additionally, with 12 cyclable brightness settings, you can operate under any light level.
Holosun HE407C-GR V2 Micro Green Dot Optic Sight
The 407c is the green dot relative to the 507c. With its green dot sight and multiple low-light settings, the 407c is ideal for hunting in the dark- especially with a pistol.
Additionally, with a rubber cover over its IP67 aluminum housing, this 407c reflex sight is particularly durable.
The 407c has the same 50,000-hour lifespan as the 507c and 510c. However, the 407c also brings the return of Holosun’s Solar Panel Failsafe™ technology.
The 407c also lacks the MRS system of the 507, keeping only 2 MOA dots. However, the Super LED light performance and green light mean that the 407c provides unlimited eye relief as it performs expertly in low light.
With 12 cyclable brightness settings (10 for daylight, 2 for night vision) and the highly-effective nature of green light at night, the 407c is the perfect option for a nighttime hunter.
Additionally, the 407c features the same multi-layer reflective glass as the 510c and 507c.
Weather & Environment
All of these reflex sights are particularly durable, regardless of the environment or temperature. All three models are waterproof and fog-proof, while the 507c and 407c are shockproof due to the recoil of certain firearms.
However, the 510c features a titanium hood to better encase its larger window. It’s hard to argue with titanium- the 510c is a notoriously durable reflex sight.
Winner- The Holosun 510c is the most durable option on this list.
Battery vs Solar Power
The 510c has the same battery life as the other models but lacks the useful solar panels of the 507c and 407c.
Winner- The 507c and 407c tie in terms of lifespan.
Green Dot vs Red Dot
The debate between red dots and green dots seems to last forever. Ultimately, it comes down to user preference.
Green dot sights are better in low-light environments and help save power, potentially granting them a longer lifespan.
However, red dots catch the eye quicker than green ones, allowing for faster target capture.
The 507c and 510c feature both red and green dots so that shooters can choose which they prefer. The 407c only offers green.
Winner- Green dots are slightly better than red dots in every aspect but speed. However, the 507c and 510c feature both red and green dots, making them tied as winners over the 407c.
The Holosun 510c features a larger window size than its competitors. Many users believe that the 510c is more convenient than the 507c or 407c due to this size.
However, the 510c is also significantly heavier and less portable than the other models. Consider this size when making your purchase.
Winner- The Holosun 510c features a larger window size and therefore is the winner of this round.
However, if you dislike the increased weight of the model, consider another option.
Each of the three reflex sights on this list comes with an including mount. The Holosun 510c comes with a Quick Detach mount, also known as a QD, while the 507c and 407c red dot sights come with a Picatinny mount.
The 510c’s mount is perfect for rifles and carbines, but it might not work as well with shotguns and pistols. Keep this in mind when making your purchase.
On the other hand, the Picatinny mount that comes with the 407c and 507cs features a low profile that is perfect for pistols, shotguns, or rifles like the AK line.
Additionally, you can easily remove the mount on your 407c or 507c to make it perfect for a pistol slide.
Winner- Ultimately, there is no overall winner for mounts. If you prefer shooting with a rifle, consider purchasing the Holosun 510c, as its included mount is perfect for rifles.
If you prefer other firearms, such as pistols or shotguns, consider purchasing a 407c or a 507c. You can differentiate between the two with any other piece of information on this list!
The Holosun 507c, Holosun 510c, and Holosun 407c all perform excellently. If performance is your main concern when buying a new reflex sight, you have plenty of wiggle room.
All three reflex sights function perfectly in a variety of environments and temperatures, whether you’re operating in the dry cold or the humid heat. Freezing and hot temperatures alike are no challenge for Holosun optics!
In terms of specs, the Holosun 407c and 507c might both feature pistol-specific functionality, but they differ in one main option. The Holosun 407c lacks the MRS system of the 507c, keeping only the 2 MOA dot feature.
Additionally, the 510c cannot use the solar panel system of the 407c and the 507c. Its 50,000 hours of battery life should give you plenty of use regardless of solar panel boosts, but it’s a nifty feature to have regardless.
Furthermore, the Holosun 510c Open Reflex Sight is significantly heavier than the 407c or the 507c. This increased weight comes with increased durability, but might not be the best choice for a reflex sight on a lightweight firearm.
Ultimately, each model has pros and cons that make them better options for different shooters.
If you prefer a simple pistol sight with no frills attached, consider the 407c. If you want more functionality, go for the 507c. If you prioritize durability, consider the 510c.
How Much Do These Optics Cost?
With the nature of the free market, there are no concrete costs for either reticle. The price of a 507c may be completely different in one store than in another and may be yet another price in an online store.
Despite the wide variety in prices, there isn’t a particularly significant price gap. The 507c and 510c typically feature the same price point, while the 407c will have a lower cost.
Ultimately, the 407c will regularly cost around 60-70 dollars less than the 507c and the 510c without factoring in shipping costs.
Ultimately, it seems like there is no clear winner in the match between the Holosun 507c, the Holosun 510c, and the Holosun 407c. However, each one is better for certain purposes.
If you prefer shooting with a rifle, the Holosun 510c is a runaway option in this competition.
You can’t get much better than this! With a larger window size, sturdier build, and optimized frame, the Holosun 510c is perfect for shooters who prefer a rifle.
If you prefer functionality, the MRS system of the 507c blows the competition out of the water.
Additionally, if you prefer hunting or shooting at night or in low-light environments, the 407c is your best option.
Choice exists because everybody has different needs and tastes. Each of these sights has benefits that measure against their opponent’s disadvantages.
For example, you may like the utility of the 507c but dislike its higher cost when compared to the 407c. Alternatively, you might like the size and durability of the 510c but dislike how it does not work well with pistols.
Ultimately, nobody can definitively claim that one of these sites is better than the other. Whether it is the Holosun 507c, the Holosun 510c, or the Holosun 407c, you can rest assured that you’ve made the right choice.
