Holosun 507c vs 510c vs 407c | Which is the Best Value Red or Green Dot?

Long-range shooting typically relies on optical sights – red or green dots, both excellent to suit different situations. Since green is more relaxing to the eyes, avid shooters sometimes ditch the classic red ones for them, especially when shooting at night.

Holosun, one of the optics and laser/IR technologies leaders, offers a broad range of military, hunting, and law enforcement products, such as the Holosun 507c, 510c, and 407c open reflex optical sights. As well as the novelty Holosun 509T made of lightweight titanium housing with maximum battery life of 50,000 hours.

The Holosun 507c, 510c, and 407c are available in both green or red dot and can last for 50,000 hours. For pistols, the 407c and 507c are ideal, while the 510c are for rifles and carbine applications. Unlike the 407c and 507c, the 510c is only powered by a battery; no solar power available.

This article will compare the Holosun 507c vs 510c vs 407c to help you decide which optical sights are the best for your shooting needs.

At the end of this post, you will learn the following:

  • How to pick the right optical sight for you
  • How each of this equipment delivers user experience
  • If these products are worth the value
  • Our overall recommendation on which optical sight you might want to choose

There’s a lot to talk about, so let’s dive in.

Holosun 507c vs 510c vs 407c: How They Compare to Each Other

All of the Holosun 507c, 510c, and 407c are open reflect optical sights, which means they use a single lens placed at the front of the scope.

The open reflex optical sights can reflect a kind of red dot sight that allows the shooter to aim at a target using both eyes, without eye relief, so that they can target quickly. However, not all red dot sights are red; they can also be green.

Since these reflex sights are not magnified, they are more ideal for close-range shooting. Reflex sights don’t have eye relief, so shooters can fire with both eyes open and still see clearly.

You’ll want to get reflex sights such as the Holosun 507c, 510c, and 407c for better and longer hours of shooting using pistols or rifles.

HOLOSUN HS507C-X2 Multi Reticle Red Dot Sight

Classic Multi Reticle Red Dot Sight (Black)The Holosun 507c is meant for pistols applications. Better than its predecessors, the latest 507c 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.

The Holosun 507c is battery and solar powered, and it can last for 50,000 hours – that’s a lot of hours of usage before charging is needed.

Using Solar Panel Failsafe™ technology, the 507c uses environmental light energy to illuminate the reticle even when a battery is absent.

A light sensor enables the reticle to automatically alter the brightness (12 brightness settings available) to suit different lighting conditions.

The Holosun 507c also features a multi-reticle system (MRS), which means shooters can utilize their optic whenever necessary only.

Shooters can switch on or off specific sections of their reticle to help them get the right one to suit different situations – 2 MOA dot or 32 MOA circles.

The 507c Shake Awake™ feature, on the other hand, activates the LED upon the slightest movement and switches off the LED when the reflex sight is not in use.

The 507c is made of titanium; therefore, it is both lightweight and durable. Using grade 5 titanium, the 507c can withstand seawater, and as the product is light, it is easy to handle and won’t add too much weight to your firearm.

Ideal for handguns, the 507c can be used for hunting during the day or at night. Shooters will have a large view that helps them shoot accurately and zero in on targets.

The 507c uses optical glass with a multi-coated lens that enables light transmission to the maximum, wear resistance, and reduced glare.

Key Features of the HS507C-X2 Multi Reticle Sight

  • 50,000 hours battery life;
  • Battery and solar power source;
  • Solar Failsafe™;
  • Multiple reticle system (MRS);
  • Super LED;
  • Night vision;
  • 2 MOA dot or 32 MOA circles;
  • Multilayer reflective glass.

Holosun HS510C 2 MOA Dot Open Reflex Circle Dot Red Dot Sight

MOA Dot Or A 65 MOA Ring Open Reflex Circle Dot Solar Power Holographic Red Dot SightLike the Holosun 507c, the Holosun HS510C 2 MOA Dot sight can operate for 50,000 hours. However, the 510c is only powered by a battery, whereas a battery or solar panel can power the 507c.

Due to its lack of solar power source, the 507c seems like a better reflex sight to have instead.

However, the 507c is designed for pistols, whereas the 510c is designed for rifle or carbine applications.

The good news is the 510c is just as efficient as the 507c. Both open reflex optical sights have excellent features, such as long-lasting battery life, the Holosun’s Super-LED, MRS, Solar Failsafe™, and Shake Awake™.

The 510c offers 2 MOA dots and a 65 MOA(Minute of Angle) ring, dot or ring only, or combinations of a dot and ring reticle.

The shooter will get an unlimited field of view. And when not in use, the reflex sight can be easily removed from the integrated QD mount that comes with the product.

Unlike the 507c that uses aluminum housing, the 510c’s housing is made of aluminum and titanium, and the hood is titanium-alloyed and shock-resistant. The difference in housing material makes the 510c stand out compared to the 507c.

Key Features of the Hs510c 2 Moa Dot Open Reflex Sight

  • 50,000 hours battery life;
  • Solar Failsafe™;
  • Multiple reticle system (MRS);
  • Super LED and night vision;
  • 2 MOA dots and a 65 MOA ring, dot or ring only, or combinations of a dot and ring reticle;
  • Multilayer reflective glass;
  • Aluminum and titanium hood;
  • A bigger window than the 507c and 407c.

Holosun HE407C-GR V2 Micro Green Dot Optic Sight

MOA Circle Dot Recticle Battery and Solar Powered Tactical Hunting Rifle Micro Green Dot Optic SightIdeal for hunting, especially in the dark thanks to its green reticle, the 407c is another excellent open reflex optical sight from Holosun.

The HOLOSUN Hunting Rifle Micro Green Dot Sight is designed for pistols, and like the 507c and 510c, the 407c can operate for 50,000 hours.

The 407c circle dot reticle only has 2 MOA dots, unlike the 507c with 2 MOA dot or 32 MOA circles, or the 510c with 2 MOA dot and a 65 MOA ring. Like the 507c and 510c, the 407c has features like the Solar Failsafe™ and Shake Awake™. And it also offers unlimited eye relief.

The 407c circle dot reticle has Super-LED that enables it to perform well in low light. A battery and solar panel power the 407c, so there is no need to worry when the battery runs out as the reflex sight will still work.

Same as the 507c, the 407c circle dot reticle has 12 brightness settings for darker environments – 10 daylight, 2 night vision.

The 407c circle dot reticle uses durable IP67 aluminum housing with a rubber cover, a multi-layer reflective glass, and a Picatinny mount. The window size of the 407c is 0.91×1.26, the same as that of the 507c – the 510c has a bigger window.

Key features of the HE407C-GR 2 MOA Circle Dot Green Dot Sight

  • 50,000 hours battery life;
  • Battery and solar power source;
  • Solar Failsafe™;
  • Super LED;
  • 2 MOA dot;
  • Night vision;
  • Multilayer reflective glass.

Holosun 407c vs 507c vs 510c: User Experience

Avid shooters use reflex sights to help them achieve better accuracy when shooting. The 507c, 510c, and 407c circle dot reticle sight are all excellent, but they’re not equal in certain situations.

While they are easy to use, you’ll want to choose the reflex sight that best suits the job you have at hand.

Weather & Environment

The 507c and 407c are made of 7075 T6 aluminum, which means they are durable, and their anodized surface coating ensures that they are weather-resistant.

You can rely on the 507c or 407c circle dot reticle in rainy, foggy, or snowy weather because they are waterproof and fog proof, just like the 510c. The 507c and 407c are shockproof so that they can deal with the recoil from a firearm.

The 507c and 407c are competitively comparable to the 510c – they’re all waterproof, shockproof, and fog proof. You might prefer the 510c for its titanium hood, though. Plus, the 510c offers a larger window, hence bigger sight.

Battery vs Solar Power

However, the 510c red dot lacks solar power, which is available with the 507c and HOLOSUN HE407C-GR V2 Elite. No solar power means that the shooter has to rely solely on their reflex sight’s battery life.

On the bright side, the 510c has a clear lens that doesn’t look blueish (it’s slightly bluish on the 507c, not a problem if you don’t find it distracting) or greenish, allowing shooters to see better what’s around them.

Green Dot vs Red Dot

The 510c is also superior to the HS507C-X2 and 407c as it gives users the option to switch between 3 reticles: 2 MOA dot, 2 MOA with 65 MOA ring, a 65 MOA ring without a dot in the middle.

The 2 MOA dot is excellent for shooting small targets from afar. Some people would love the circle dot reticle as it makes it easier for the eyes when shooting quickly up-close.

Holosun offers 507c and 510c with the red or green reticle, which is great because people can choose the color that suits them better.

The red dot is better than the green in terms of speed as it can catch the eye quicker, hence quicker target capture. The red dot is also a better choice when shooting in jungly environments.

However, green lights are ideal in low-light. Older shooters or individuals with weaker eyesight may also opt for the green dot to put less strain on their eyes when using the reflex sight for an extended period. The green dot is more power-saving than the red dot, too.

Window Size

In terms of window size, users may find the 510c better and more convenient than the 507c and 407c circle dot reticle green dot sight.

The Holosun 510c, however, is heavier than the 507c and 407c due to its construction material. In terms of portability, the 507c and 407c are more compact than the 510c.

Mounting Options

All three reflex sights come with a mount: Quick Detach (QD) mount for the 510c and Picatinny mount for the HS507C-X2 Multi Reticle Red Dot and 407c. So, you won’t need to spend extra money on a reflex sight mount before you can start using the optic.

Please take note that the reflex sight mount you get for the 510c is designed for rifles or carbine applications, so you may not want to use it for other types of guns like an AK or a shotgun.

The 507c and 407c’s Picatinny mount is low, unlike the one used with the 510c. The Picatinny mount is designed for pistols or firearms like AKs or shotguns. You can easily remove the 507c or 407c mount, perfect for pistol slide.

Holosun 407c vs 507c vs 510c: Performance

In terms of performance, all three reflex sights are excellent. They are durable and can operate for very long hours. Below is a pretty cool video of how the 507c performs in different environments:

If you want to get a reflex sight for your pistols, go for the 507c instead of the 510c. The 510c is designed for rifle or carbine applications, and it comes with a high mount, not suitable for pistols.

While the Holosun 407c is excellent for pistols, it does not have MRS, unlike the 507c, and only has the 2 MOA dot feature, which is reasonably good if you want to keep it simple.

The 510c cannot be powered by solar, which is a shame, but the 50,000 hours of battery life are enough to keep you on the go before the next charging.

The Holosun 510c Open Reflex Sight is not as lightweight as the 507c and 407c, which will add some weight to your firearm. That’s okay, though, because the 510c’s strong titanium and aluminum built is worth the extra weight.

All three Holosun reflex sights can be used in freezing and hot temperatures, between -30℃ and 60℃ – this shows how strong they are.

Even if you accidentally drop them on the floor, they can still work correctly. The buttons of the 507c are tiny, though, which is understandable, but it can be a little bit difficult to press.

Holosun 407c vs 507c vs 510c: Pricing

The prices of the 507c, 510c, and 407c are reasonable for the features and high quality they offer. The 507c and 510c cost the same, while the 407c is cheaper.

The best part about all three reflex sights is their battery life, and for that feature, along with other excellent features and the products’ construction quality, they’re a value for money.

Overall, the 510c is an excellent reflex sight for rifle and carbine applications. If you need a reflex sight for pistols, you might want to consider taking the 507c instead of the 407c.

In that case, you’d only need to pay a little extra (but less than a hundred dollars) to get extra features, like the MRS.

If you want to place the sight on a rifle, take the 510c, but if you want a more compact optic, you can mount on a pistol slide or a gun that uses a low-mounted optic, then go for the 507c.

Frequently Asked Questions (FAQs)

Is a red dot sight durable and reliable?

Yes, many red dot sights, including the Holosun 510C and 507C, are made from durable materials and are built to withstand recoil and tough conditions.

What is the battery life of a red dot sight?

Battery life varies between red dot sight models and can range from several thousand hours to over 50,000 hours. The Holosun 507C has a battery life of up to 50,000 hours, while the Holosun 510C has a battery life of up to 100,000 hours with the solar panel.

What is the difference between a red dot sight and a holographic sight?

A red dot sight projects a single red dot onto the lens, while a holographic sight projects a reticle that appears to be floating in front of the sight. Holographic sights tend to be more expensive and have a more complex reticle.

How do I choose the right red dot sight for my firearm?

When choosing a red dot sight, consider factors such as the intended use, the type of firearm, personal preference, and budget. Research different models and read reviews to find the best option for your needs.

What is the warranty for red dot sights?

The warranty for red dot sights varies between manufacturers and models. The Holosun 507C, 510C and 407c come with a limited lifetime warranty.

Final Thoughts: Holosun 507c vs 510c vs 407c

The 507c, 510c, and 407c are all excellent reflex sights from Holosun. They’re all durable, weather-resistant, shockproof, and easy to use. The best feature of all three products is the 50,000 hours of battery life.

The HS507C-X2 Classic Multi Reticle Red Dot Sight and HOLOSUN HE407C-GR Micro Green Dot Optic Sight are ideal for pistols, whereas the 510c is suitable for rifle and carbine applications.

The HS510C Solar Power Holographic Red Dot Sight and 507c stand out when compared to the 407c. However, if you’re on a budget and want to keep it simple, the 407c is an excellent option.
