Last Update:

Hey Shooter, Welcome to My Blog of Holosun 510C Problems in 2023.

To feel at ease when shooting, you must immediately address and solve the problem with your red dot sight. Products from Holosun frequently perform well and arrive in excellent condition. So, what could be the issue with the holosun products?

In this review, I discussed the issues that many shooters, including myself, have with the Holosun 510c. These issues are mostly related to the power system and the reticle. Nevertheless, there is no need to worry about these issues because a solution exists for every issue.

Let’s start with an overview of the holosun 510c, and then I’ll go over the problems you should be aware of before purchasing the holosun 510c. Additionally, if you are already dealing with such issues, use the provided solutions to deal with them.

Quick Table: Holosun 510C Problems & Solutions

Blinking ReticleReplace with a new CR-2032 battery or get the sight replaced under warranty if it’s a flaw.
Illumination AdjustmentPurchase from reputable sources; consider replacing the sight or get it repaired by the company.
Shake-Awake FeatureHandle sight carefully and consider repair through seller or Holosun directly.

Problems With The Holosun 510C To Be Aware Of

1. Blinking Reticle

Blinking reticles in the Holosun 510c have been reported by some shooters. It might be an issue with the reticle, such as a flaw. Shooters who have expressed dissatisfaction with the reticle’s blinking haven’t given a convincing defense. The reticle blinking to signal a low battery alarm was the other instance I’ve encountered, though.

It was essentially a battery-related alert that was set up for you. If the battery is not working properly, the reticle will not function properly. 


If the sight has a flaw, it must be replaced, either through the warranty card offer or by purchasing a new item. If, however, it’s a sign of a low battery, the problem can be fixed by simply replacing the battery. The Holosun 510c uses a CR-2032 battery cell, which is inexpensive and widely available. The problem with the blinking reticle will be resolved right away after changing the battery.

2. Illumination Adjustment Buttons

Several shooters have reported that the illumination adjustment buttons do not work properly. They mean that the buttons are not jammed; they are moving, but there is no after-effect from those buttons. The illumination is simply constant, and neither the night vision nor the light work.

No one can shoot using a red dot sight like this at this point. So what must the shooter do for the illumination adjustment buttons to begin functioning? According to my personal experience, these issues are frequently found in substandard products that might have originated from totally fake websites.


The only solution to this problem is to purchase a new product for your weapon. You can buy it from the manufacturer’s website or any seller. Otherwise, request a replacement from the company if the optic is defective right away. The company’s warranty offer states that it will replace the faulty product. Send the product to the company to have the illumination control buttons repaired if the manufacturer won’t accept the replacement.

3. Shake-awake Feature

A few shooters have also complained about the shake-awake feature not working. The purpose of adding the shake-awake feature in the red dot sight is to let the sight power on and off automatically. 

The shooters have said that the shake-awake feature is not working, as in there is no effect if the sight detects a movement. It has not completely stopped working. Sometimes it turns the sight off if there is no movement. But no effect when detecting the movement.


Try to handle the sight carefully so that these features work fine for a long time. Try to get it repaired by the seller of the product or send it directly to the Holosun company.

4. Night Vision

There are two illumination settings for night vision on the holosun 510c. These two illumination buttons make night shooting simpler. Aiming at the target at night is impossible without making these two adjustments. The broken illumination adjustment buttons I mentioned earlier are connected to this problem.

It could be due to a manufacturing time error or broken adjustment buttons. With my first Holosun 501c, I never ran into this issue. Few users of the fake Holosun 510C do, however, experience this issue.


To solve this problem, the user of the product can either switch the product with the newly bought holosun 510c product or can send it to the vendor for repair. Other than these two options, there is no way to solve the problem. 

5. Power on/off

A few shooters have also reported difficulties turning the sight on and off in addition to the button and feature-related issues. The battery might be the cause of this. Incorrect battery installation in the battery compartment has occasionally occurred. Because the shooter encountered these issues shortly after unboxing, this could be a possibility.

Also, it is an indication that you got a fake product, as I have personally experienced that. When I got the fake product, it did not turn on at first. I tried everything to power on sight, but nothing happened.  


If your red dot sight does not function properly, try adjusting the battery in the battery compartment. You’ll be able to turn on the sight with no problem by doing this. If your red dot sight still does not work, purchase another battery and use it.

Wrapping It Up!

The Holosun 510C is only a valuable purchase if you get the original product from a trustworthy source. The Holosun 510c has two features that, in my opinion, elevate it above the competition. Holosun has a multiple reticle system that allows you to aim precisely and quickly at the same time. Furthermore, it has two power systems that benefit from each other if one fails to provide the service.

Shooters commonly encounter the aforementioned problems as a result of making poor purchases or handling their sights improperly. But those problems can be resolved in some sort of manner.
