Holosun Technologies Recalls Two Firearm Dot Sights Due to Battery Ingestion Hazard; Violations of Reese's Law Federal Safety Regulations for Consumer Products with Coin Batteries and Child Resistant Coin Battery Packaging

What was recalled

In February of this year, specifically on February 20, 2025, the U.S. Consumer Product Safety Commission (CPSC) announced a significant safety recall involving two specific models of firearm accessories manufactured by Holosun Technologies. If you are a gun owner or have recently purchased shooting equipment, it is important to know exactly which items are affected. This recall targets the Holosun Red Dot Sight, identified by the model number HS503G-ACSS, and the Holosun Gold Dot Sight, known as model HE512C-GD. These are not general firearms but rather precision accessories designed to attach directly to a firearm, providing an illuminated colored dot to help with aiming accuracy.

To determine if your device is part of this recall, you need to look closely at the physical product and its original packaging. The affected units are characterized by their matte black finish. When you examine the item, you should find the specific model number printed on the packaging sleeve, the outer box, the included instruction manual, and the product display panel. Each of these recalled sights comes packaged with a single CR2032 lithium coin battery. It is this specific battery configuration that triggers the safety alert, rather than the optical or electronic components of the sight itself.

The recall applies to units sold during the period leading up to the announcement date. While the specific start and end dates of sales are not detailed in the current public record, the CPSC notes that Holosun Technologies is actively contacting all known purchasers directly. This suggests a broad distribution network for these models. If you purchased either the HS503G-ACSS or HE512C-GD from authorized retailers, online marketplaces, or directly from Holosun, your device may be included in this batch.

It is crucial to understand that this recall is not based on a malfunction of the sight’s ability to illuminate or aim. Instead, it is a regulatory compliance issue regarding how the power source is secured. The products were sold with a lithium coin battery that could be easily accessed by children, violating federal safety regulations known as Reese's Law. This law mandates that consumer products containing button cell or coin batteries must have child-resistant packaging and clear warnings. Because these Holosun sights lacked those required protective barriers and labeling, they pose a hidden danger to households with young children, even though the product itself functions correctly for its intended shooting purpose.

The hazard, explained

To understand why the Holosun Technologies recall is so critical, we first need to look at what makes these specific dot sights non-compliant and dangerous. The recalled Red Dot Sights (Model HS503G-ACSS) and Gold Dot Sight (Model HE512C-GD) are designed to attach to firearms, providing an illuminated aiming point. While the optical technology is sophisticated, the power source inside is surprisingly simple: a standard CR2032 lithium coin battery. Under normal circumstances, these small batteries are safe. However, the core issue here is not the battery itself, but how it is housed within the device.

The U.S. Consumer Product Safety Commission (CPSC) has identified that the battery compartment in these recalled Holosun models does not meet mandatory federal safety regulations known as Reese’s Law. This law was enacted to prevent children from accessing button cell or coin batteries, which are often found in watches, calculators, and remote controls. In the case of these dot sights, the design allows the lithium coin battery to be easily accessed without requiring tools or significant effort. There is no child-resistant mechanism in place to keep a curious hand or tooth from reaching in and removing the power source.

Why does easy access matter so much? The danger arises when a child swallows a button cell battery. It is not merely a choking hazard; it is a chemical emergency. Once ingested, the battery can become lodged in the esophagus, the tube that carries food from the mouth to the stomach. Within just two hours, the battery creates an electrical circuit with bodily fluids. This process causes a rapid release of current that leads to severe internal chemical burns, tissue necrosis (tissue death), and potentially fatal perforations of the esophagus or other surrounding structures. The injury happens quickly and can be devastating, even if the child shows no immediate symptoms.

Compounding this physical accessibility issue is the lack of required visual warnings. Federal regulations mandate that products containing these batteries must bear clear warnings about the ingestion hazard. The recalled Holosun units do not include these required labels on the packaging or the device itself. This means a consumer might purchase the sight, unaware that the battery inside poses such a severe risk if accessed by a child. Furthermore, because the devices were sold with lithium coin batteries that are not in child-resistant packaging as required by law, any household keeping these sights must treat them as potential sources of serious injury until they are properly secured.

It is important to note that while no incidents have been reported to date, the potential for harm is inherent in the design flaw. The combination of an easily accessible power source and the absence of mandatory safety warnings creates a situation where a simple oversight by a parent or guardian could lead to a life-threatening emergency for a young child. Understanding this mechanism helps explain why the remedy involves not just stopping use, but physically modifying the battery compartment to make it inaccessible to small hands.

Who is most at risk

The primary group of individuals who may possess the recalled Holosun Firearm Dot Sights consists of firearm owners and enthusiasts who have purchased either the Red Dot Sight (Model HS503G-ACSS) or the Gold Dot Sight (Model HE512C-GD). These devices are specialized accessories designed to attach to firearms, providing an illuminated aiming point for precision shooting. While the product is marketed toward adults engaging in recreational shooting, hunting, or tactical training, the safety hazard associated with these units does not discriminate based on the owner’s intent or expertise. The risk arises not from the function of the sight itself, but from the way its power source is contained.

The most vulnerable individuals are children, particularly those under the age of five. According to the U.S. Consumer Product Safety Commission (CPSC), young children are naturally curious and often explore their environment by putting objects in their mouths. The recalled sights contain a CR2032 lithium coin battery that is easily accessible due to non-compliant packaging requirements mandated by Reese’s Law. This law was enacted specifically to prevent the ingestion of button cell batteries, which pose a severe and rapid threat to small bodies. If a child manages to access the battery compartment of one of these recalled sights, they may swallow or insert the battery into their nose or ear.

The danger to children is not merely mechanical; it is chemical and biological. When a button cell or coin battery is swallowed, it can become lodged in the esophagus. Within just two hours, the battery can generate an electrical current that causes rapid tissue damage, leading to severe internal chemical burns, perforation of the esophagus, and potentially fatal complications such as aortic rupture or infection. Because young children have smaller airways and digestive tracts, even a single standard lithium coin battery represents a life-threatening emergency. The fact that these specific Holosun models lack the required child-resistant packaging and warning labels significantly increases the likelihood of accidental access in homes where firearms are stored.

While elderly individuals or those with cognitive impairments might also handle these devices, the immediate and catastrophic risk highlighted by this recall is centered on pediatric ingestion. The CPSC notes that no incidents have been reported to date, but the potential for harm remains high because the design flaw allows for easy battery removal without tools or significant effort. Therefore, any household containing young children who have access to firearms, shooting ranges, or areas where these sights are stored must treat this recall with the utmost urgency. The presence of a firearm in the home does not mitigate the risk; rather, it underscores the need for strict separation of ammunition, accessories, and power sources from areas accessible to minors.

How to tell if you have the recalled item

Before taking any action, you must first confirm whether your specific device is part of this recall. Because Holosun Technologies manufactures several different optical accessories, it is crucial to distinguish between safe models and those affected by this safety notice. The recall is not a blanket condemnation of the entire brand but targets two very specific product lines: the Red Dot Sights with model number HS503G-ACSS and the Gold Dot Sight with model number HE512C-GD. If your device does not match one of these exact alphanumeric codes, it is likely not included in this particular safety alert.

To verify your item, you should check multiple locations on the product and its packaging. Start by looking at the original retail box. The model number should be clearly printed on the packaging sleeve, the exterior box itself, and the manual included inside. Holosun is quite consistent with its labeling, so the product name and specific model identifier will appear together on these items. If you have already mounted the sight onto your firearm or stored it away from its original box, look directly at the device. The matte black finish of these dot sights serves a functional purpose for concealment, but the identification markings are still present. Check the product display panel and the main body of the sight itself for engraved or printed labels that confirm the model number.

Pay close attention to the visual design of the optic. Both recalled items are described as producing an illuminated color dot for precision aiming, which is standard for this type of firearm accessory. However, the specific finish and model designation are your primary identifiers. The HS503G-ACSS is identified as a Red Dot Sight, while the HE512C-GD is the Gold Dot Sight. Both units come with a matte black color scheme and include one packaged CR2032 lithium coin battery. If you purchase these items second-hand or find them in a storage container without clear labeling, you must attempt to locate the model number on the device housing or any remaining documentation. Without a confirmed match to either HS503G-ACSS or HE512C-GD, you cannot definitively conclude that your item is part of this recall. When in doubt, contact Holosun Technologies directly with photos of the labeling for confirmation.

What to do — step by step

Your refund, repair, or replacement options

If you own one of the recalled Holosun Firearm Dot Sights, specifically the Red Dot Sight (Model HS503G-ACSS) or the Gold Dot Sight (Model HE512C-GD), you do not need to worry about navigating a complex refund process or paying for repairs out of pocket. The remedy provided by Holosun Technologies is designed to be straightforward and entirely free for consumers. It is important to understand that this recall is not primarily about financial compensation; rather, it is a safety correction. The company is addressing a critical engineering and packaging flaw that violates federal safety regulations regarding button cell batteries. Therefore, your primary "option" is to accept the corrective action they are offering to make your device safe to use again, or to choose not to use it at all.

Holosun Technologies has already taken the proactive step of contacting all known purchasers directly to inform them of the issue. However, if you have not heard from them yet, or if you simply want to take control of the situation yourself, you can initiate the process by reaching out to their support team. You should contact Holosun Technologies toll-free at 888-869-1180 between 8:30 a.m. and 5 p.m. Pacific Time, Monday through Friday.

Please remember that you are not being asked to pay for any of these services or parts. The entire process—from the shipping materials to the hardware replacement—is covered by the manufacturer. The goal is to eliminate the ingestion hazard posed by the accessible lithium coin battery without placing any financial burden on the consumer. Once your device has been processed and returned, it will be safe from the specific risk that prompted this recall. If you choose not to participate in the repair process, ensure the device remains inaccessible to children and dispose of or recycle the hazardous batteries according to local hazardous household waste procedures.

What can happen if you ignore it

It is completely understandable to feel reluctant to stop using a piece of equipment that you have invested time and money into, especially when it has been functioning correctly for you. You might be thinking that because no accidents have been reported yet with these specific Holosun sights, the risk must be minimal or theoretical. However, ignoring a recalled safety hazard is never a gamble worth taking, particularly when the potential consequences involve severe biological injury. The core issue here is not whether the sight will fail to illuminate your target; it is that the device itself has become an inadvertent trap for anyone in your household who does not understand its contents.

The primary danger lies in the specific design flaw identified by the CPSC: the lithium coin battery inside these sights is easily accessible. Unlike standard consumer electronics where batteries are secured behind tight, screw-down compartments, the recalled Holosun HS503G-ACSS and HE512C-GD models allow for easy removal of the power source. If you continue to use or store these sights in a home environment, you are leaving a high-energy lithium battery within reach of children or pets. The hazard is not just that a child might swallow a battery; it is what happens immediately after ingestion.

When a button cell or coin battery is swallowed, it can become lodged in the esophagus. At this point, a dangerous chemical reaction occurs. The battery completes a circuit with bodily fluids, generating an electrical current that causes rapid tissue damage. This results in severe internal chemical burns that can perforate the esophageal wall within just two hours of ingestion. These are not minor injuries; they are life-threatening emergencies that often require complex surgical intervention to repair damaged tissue and prevent infection or death. The speed at which this damage occurs is why safety regulators treat battery ingestion with such urgency.

Furthermore, while the recall notice states that no incidents have been reported to date, this silence is not a guarantee of safety. It merely means that, so far, no one has come forward with an injury report. Relying on the absence of bad news as proof that a product is safe is a logical fallacy known as survivorship bias. You cannot know if your specific unit is safe until it causes harm, and by then, it is too late to take preventive action. The lack of reported incidents should not be interpreted as "low risk"; it should be interpreted as "untested in the wild." Every day you keep these sights accessible, you are increasing the statistical probability of a catastrophic event occurring in your home.

Additionally, there is the secondary hazard of improper disposal. If you choose to ignore the recall but decide to simply throw the device away rather than returning it, you risk placing hazardous lithium batteries into the general waste stream. These batteries can ignite in garbage trucks or landfills, posing a fire risk to sanitation workers and environmental contamination for the community. Ignoring the recall instructions thus creates two distinct dangers: an immediate threat to your household’s health through potential ingestion, and a broader public safety threat through improper hazardous waste handling.

Ultimately, the remedy provided by Holosun Technologies is designed to eliminate these risks without forcing you to buy new equipment. By taking the time to follow their instructions, you are not just complying with a regulation; you are actively securing your environment against a silent, fast-acting hazard. The convenience of continuing to use the sight as-is is vastly outweighed by the irreversible physical trauma that can result from a single moment of carelessness.

Staying safe: broader tips

While this specific recall addresses a critical failure in battery packaging for firearm accessories, the underlying safety principle applies to a vast array of household items. Button cell and coin batteries are ubiquitous, found not just in specialized optics but also in remote controls, hearing aids, key fobs, calculator watches, and many modern toys. The danger they pose is unique and severe because the injury mechanism is chemical, not just mechanical. When these small, shiny batteries are swallowed, even by children who may not understand what they are, they can become lodged in the esophagus. Within just two hours, the battery creates an electrical current that generates hydroxide at its tip, causing rapid and deep tissue burns. This is why general prevention must focus on both physical barriers and environmental awareness.

The most effective defense against ingestion hazards is proactive storage management. Never leave items containing coin batteries loose in drawers or accessible on low tables. Instead, utilize locked cabinets or high shelves that are completely out of reach for young children. If you have older children who might experiment with these objects, educate them early and clearly about the dangers of putting anything small into their mouths or ears. Treat all button cell batteries with the same caution as medication; store them in their original packaging until use, and immediately dispose of empty batteries by taping the terminals with clear tape to prevent accidental contact with metal objects like keys or coins in a trash bin.

Furthermore, stay vigilant about product safety regulations and recall notifications. Laws like Reese’s Law have tightened requirements for child-resistant packaging specifically because previous designs were often too easy for toddlers to open. To protect your home, regularly check the Consumer Product Safety Commission (CPSC) website or sign up for their email alerts. Installing a carbon monoxide detector is another vital step in general home safety, as these devices also rely on batteries and require regular maintenance checks to ensure they are functioning correctly. By combining secure storage practices with routine awareness of safety updates, you create a layered defense that keeps your family safe from both specific product failures and broader household hazards.
