Holosun 510C Red Dot Sight Review – Worth Buying?

Hey Shooter! Welcome to my holosun 510c red dot sight review in 2023.

Let’s start with, Is it worthwhile to purchase a Holosun 510C? YES, in all respects. Your purchase of the Holosun 510C won’t ever be a mistake. Every feature a shooter could want is included in the Holosun 510C. I’ve used several holosun sights, but Holosun 510C is phenomenal. But before buying the Holosun 510C, I had the following thoughts: Is the cost justified? However, I would not trade Holosun 510C for anything once I had purchased it.

Holosun 510C features tend to involve a Multiple-Reticle System (2 MOA, 65 MOA, and Both at Once), a two-way power supply, an exceptional battery, detach mount, shake awake technology (which turns the LED on/off when it detects motion), etc.

Holosun 510C Features and Benefits

1. Optic Clarity and Reticle

The extremely well-designed holosun 510C offers a great experience. Holosun 510C sight’s optic clarity and reticle will astound you with their exceptional appearances, like the QD mount and the multiple reticle options. Red dot sights’ reticle design and large view are vital, but many purchasers don’t give them much thought before they buy the sight.

Large field of view

The Holosun 510C has a “multi-layer coating” that guarantees a better sight. The Holosun 510C sight offers a broad field of view. Basic sense, the optic allows for much greater peripheral vision, which is preferable for shooting.

Multiple reticle systems

One of the standout benefits of the holosun 510C is the ability to use multiple reticles. Holosun 510C provides the option of using a 65 MOA circle or the more precise 2 MOA red dot. Besides that, you can use both the 2 MOA dot and the 65 MOA simultaneously. What more could one shooter ask for? A combination of 2 MOA red dots and 65 MOA circles make up the standard reticle. Suppose you have no idea how to switch between reticles. Read the next statement. To switch between reticles, firmly press and keep pressing the “-” button until the reticle changes, then release the button. 

Parallax-free

Holosun 510C is also parallax-free, which should not be disregarded. However, there may be very slight discrepancies. Compared to other types of red dot sights, holographic sights just provide the finest parallax-free experiences.

2. Source of Power

In addition to battery systems “CR-2032 lithium battery”, the holosun 510C reticle can be powered by a solar panel. It implies that your sight is constantly charged.

Pre-installed battery

A holosun 510C comes with a pre-installed battery, which is convenient for you. Yes, the battery is a CR2032, which is among the best batteries.

Dual power source

The dual power supply is the Holosun 510C’s plus point. The two power sources that the holosun offers are as follows.

• Battery (Can’t be recharged)
• Solar Panel

Battery life varies from 20k hours (for 65 MOA circle) to 50k hours (for 2 MOA + 65 MOA). However, when the battery runs out, and Holosun 510C switches to the solar panel instantly, the solar panel does not produce a much brighter red dot than the battery. The power generated by the sun’s rays and batteries is different. However, it won’t significantly affect your shooting.

Failsafe feature

The assisting hand that appears when required is the solar failsafe feature. The reticle can continue functioning even if your battery dies big ups to Solar Failsafe. Yes, I am referring to the same solar panel power here.

3. Durability and Reliability

The level of durability offered by the holosun 510C is spectacular. I am stating this based on my testing, not just what others have said. I put the holosun 510C to the fullest extent of my testing capabilities. For example, Holosun claimed that the device was shock, water, and fog proof. So, I put holosun’s claims to the test. It passes as expected. Additionally, the holosun 510C is reliable in addition to being durable. 

Aluminum Housing

The body of the optic, excluding the lens, is made of aluminum. How, then, can the aluminum body of the optic benefit? It helps because it makes the optic lighter.

Titanium Hood protection 

A titanium hood shields the optic lens in the Holosun 510C. Since titanium is both robust and light, it works perfectly with the optic’s lightweight.

Resist all climate conditions

As previously stated, Holosun claims that the 510C sight can resist all weather patterns, which I checked. Believe me. The holosun 510C can genuinely resist any weather.

Shockproof

In addition to being weather resistant, the holosun 510C sight is also shockproof, so even if you drop it from any height, it won’t break. Just don’t fling it out of the plane. There is no longer a concern regarding the Holosun 510C’s malfunction.

Lightweight

The Holosun 510C is lightweight due to its body’s composition, “The Aluminum,” which adds incredibility to this sight. With dimensions (LXWXH) of 3.3×1.68×1.78 inches and weighing only 4.94 ounces, it is sturdy and reasonably sized.

Limited lifetime warranty

With no extra charges, Holosun 510C offers a lifetime warranty. However, holosun disclaims all responsibility for every incidental or special damage to the product.

4. Mounting and Zeroing

It is simple to mount the optic and zero the sight. As soon as that’s done, you can start firing and hit the target accurately. As recommended by holosun, mount it on a rifle.

Quick detach mount

A “quick detach mount” is part of the Holosun 510C, which I genuinely love. The QD mount makes it extremely quick to attach and detach this red dot sight from various rifles. A “cam clamp lever” holds firmly and safely to Picatinny rails. It couldn’t be more convenient to use, and it’s ideal if you frequently change your sights.

The “Torx socket” that stimulates and adjusts the reticle could be turned to stiffen or unscrew the “cam clamp” lever’s grip on the rail. There shouldn’t be any worries about its capacity to withstand frequent recoil because it is convenient to use.

Windage and Elevation

When you purchase a holosun 510C, its sight is already zeroed but still needs to be adjusted. A “wrench” that is supplied with the holosun 510C can be used to zero the sight (you can use any suitable tool) by putting the wrench into the holes and then twisting it.

5. Brightness Adjustment

Simply using “+” and “-” will authorize you to adjust the reticle’s brightness. However, I’ll explain what else is possible with these two buttons in this section. The Holosun 510C sight can first be turned on or off by tapping either “+” or “-,” and it can be turned off by pressing both buttons concurrently. The second is that there are two modes that you can choose from: automatic and manual.

Auto-mode and manual mode

When the “+” button is depressed for two to three seconds, the automatic mechanism is activated, helping to adjust illumination in response to ambient light. The reticle size can be altered, and the illumination can be manually changed in manual mode.

10-levels (for daylight) and 2-levels (for night vision) of brightness adjustment are available.

Night Vision

Holosun 510C night vision passes the compatibility test, and the two lowest brightness settings can be used without risk with a night vision device. To obtain the appropriate brightness configurations, the Holosun 510C should be in “manual mode.”

Shake-awake feature

You can make turning on and off the optic easier with the support of the Holosun 510C shake-awake function. This feature is motion-based, so when the optics observes displacement, the sight will power on, and if there is no movement for about two minutes, the sight will power off automatically. It means you are always ready to take action if there is a threat.

6. Eye Relief

I can attest from personal experience that holosun 510c provides infinite eye relief. Holosun 510C sight works well for astigmatic people because it does not distort.

The Drawbacks of Holosun 510C Sight

The Holosun 510C is an incredible red dot sight with many benefits but few drawbacks. I am unaffected by the drawbacks mentioned above, and I don’t even classify them as such. However, these are a few;

• The Holosun is a heavy sight
• No green reticle is present on the optic, and the MOA ring is colorless.
• There is no lens cloth included with Holosun.

What You Get In a Box

With the Holosun HS510C, a fair amount of cool extras are included. You get;

• A tool for quickly removing the battery tray
• QD mount
• High-quality extra battery tray

Use of magnifiers with Holosun 510C Sight

When shooting at close range, the Holosun 510C thrives. Nevertheless, you should consider purchasing a magnifier if you intend to expand the range to even more than 100 yards. It stands to reason to augment it with cost-effective but high-quality goods.

Recommendation:

• Holosun 3x HM3X (a flip-to-side mechanism)
• Sig Sauer Juliet3 Micro (compact magnifier)
