What was recalled
If you own a SIG SAUER ROMEO5 Red Dot Sight, it is important to know exactly which units are affected by this recent safety alert. The Consumer Product Safety Commission (CPSC) has announced that specific models of these popular firearm optics are being recalled due to serious safety violations regarding their internal battery packaging. This recall specifically targets the SIG SAUER ROMEO5 Red Dot Sights, with model numbers SOR52001 and 7400579. It is also worth noting that this issue extends to units where the sight is included as part of a package; if you purchased the Model SORJ53101, your unit is included in this recall as well.
To help you identify whether your specific device is part of this batch, look closely at the physical product and its original packaging. The recalled optic sights are black in color and come pre-installed with one CR2032 button cell battery. On the side of the device, you will see the SIG SAUER logo alongside the "ROMEO5" name. However, the most critical identifier is located on the bottom of the sight itself. You need to check the serial number printed there. The recall applies only to those units where the last digit of the serial number is either the letter "K" or the letter "M." If your serial number ends in any other character, your unit is not part of this specific recall action.
While the official CPSC record does not provide a precise total count of the affected units or list the specific retail stores where these items were sold, it is clear that these products are widely distributed among firearm owners who rely on them for accuracy. The absence of specific sales location data in the current report means you must rely on the model and serial number checks described above to determine if your gear is at risk. The recall was officially announced on January 8, 2025, marking a significant step by both SIG SAUER and federal regulators to address the dangerous design flaw that allows easy access to the battery compartment.
This situation highlights why verifying the model number and serial suffix is crucial. Because these sights are often sold as part of bundles or through various online and brick-and-mortar retailers, keeping your original packaging can be helpful for locating the model number quickly. If you have lost the box, the model information is also typically printed on the device itself or in your purchase records. By confirming that your ROMEO5 sight matches one of the listed models (SOR52001, 7400579, or part of SORJ53101) and has a serial number ending in K or M, you can take the necessary next steps to secure your safety.
The hazard, explained
To understand why this recall is so urgent, we need to look at what physically happens inside these SIG SAUER ROMEO5 Red Dot Sights when they are not handled correctly. The core issue lies in the power source: a CR2032 button cell battery. While these tiny batteries are standard for many small electronics, they pack a significant amount of energy into a very small space. In this specific recall, the design of the sight allows the battery compartment to be opened easily. There is no child-resistant locking mechanism or complex screw system that would prevent a young child from accessing the power source. This means that if the device is left within reach, a curious child can pry open the cover and remove the battery without any difficulty.
The danger escalates rapidly once the battery is removed and swallowed. When a button cell battery is ingested, it does not simply pass through the body like food or water. If the battery becomes lodged in the esophagus—the tube that carries food from the mouth to the stomach—it creates a catastrophic medical emergency. The human body’s natural moisture and salts interact with the metal components of the battery, creating an electrical circuit. This process, known as external tissue injury, generates hydroxide ions at the negative pole of the battery. These ions are highly alkaline and cause immediate, severe chemical burns to the surrounding tissues.
This injury is not gradual; it can occur in as little as two hours. The burning can erode through the esophageal wall, damaging nearby critical structures such as major blood vessels or the trachea. This can lead to life-threatening hemorrhaging, fistulas (abnormal connections between organs), and permanent tissue damage. Because the battery is so small, it may not cause immediate choking or discomfort, which means parents might not realize something is wrong until significant internal damage has already occurred. The CPSC highlights that these injuries are often severe and can be fatal if not treated immediately with emergency medical care.
Compounding this physical danger is the regulatory context known as Reese’s Law. This federal regulation was established to prevent precisely these types of incidents by requiring that consumer products containing button cell batteries have packaging that children cannot easily open, along with clear warnings on both the product and the package. The recalled ROMEO5 models fail on all three counts: the battery is accessible, the packaging is not child-resistant, and the required safety warnings are missing. Without these barriers, the device relies entirely on adult supervision to prevent access, which is not a reliable safety strategy when dealing with small, ingestible objects that pose such a high risk of internal chemical injury.
Who is most at risk
The primary group of individuals who need to take immediate action in this recall are the owners and users of SIG SAUER ROMEO5 Red Dot Sights, specifically those with Model numbers SOR52001 and 7400579, as well as units included with Model SORJ53101. While firearm enthusiasts and tactical shooters who rely on these optics for accuracy and performance are the direct users of the product, the safety risk extends far beyond just the person holding the weapon. The core issue here is not mechanical failure or poor visibility, but rather a chemical hazard stemming from the internal power source. Therefore, the people most at risk are anyone in close proximity to this device—particularly children, caregivers, and household members who might encounter the sight during storage, cleaning, or accidental drops.
The vulnerability of young children is the central concern driving this recall under Reese’s Law. Children under the age of five are naturally curious and explore their environment by putting objects in their mouths. They may not recognize a small, coin-sized battery as dangerous, especially if it is loose or accessible within the sight’s housing. The recalled sights contain a CR2032 button cell battery that does not meet the mandatory child-resistant packaging standards required by federal law. This means that if the battery compartment can be opened—whether through normal use, wear and tear, or deliberate tampering—the battery is easily accessible. For a small child, swallowing even a single button cell battery can be catastrophic. The hazard is not just choking; it is chemical. Once ingested, the battery can lodge in the esophagus, where it generates an electrical current that causes rapid tissue damage, leading to severe internal burns, perforation of organs, and potentially death. This process can begin in as little as two hours, making time a critical factor.
Elderly individuals or those with cognitive impairments may also be at risk, not necessarily from ingestion, but from the potential for accidental exposure if they handle the device without understanding its hazardous components. Additionally, any household member who assists in storing these sights must recognize that this is not a standard piece of equipment to be left open or unsecured. The lack of required warning labels on the recalled units means there is no immediate visual cue to alert anyone that a dangerous power source is present. This absence of clear labeling increases the risk for anyone who might disassemble the sight for maintenance or cleaning without knowing the proper safety protocols. Consequently, the entire household environment where these sights are kept becomes a potential hazard zone until the free recall kit is installed. It is crucial to treat the device as if it contains an exposed toxic component until the new cap and updated manual are provided by SIG SAUER.
How to tell if you have the recalled item
Determining whether your firearm optic is part of this specific recall requires a careful, methodical inspection of both the device itself and its original packaging. Because the hazard involves internal components that are not immediately visible during normal operation, you cannot rely on how the sight looks when mounted on a gun or how it functions. You must physically locate specific printed identifiers to confirm if your unit is among those affected. This process may feel tedious, but it is the only reliable way to ensure your safety and eligibility for the free remedy package.
First, verify the brand and model name. The recalled products are SIG SAUER ROMEO5 Red Dot Sights. You should look for the "SIG SAUER" logo and the "ROMEO5" name clearly printed on one side of the product body. While many optics share similar black finishes, this specific recall applies only to units sold with a single packaged CR2032 button cell battery included in the box. If you purchased your sight used or without original packaging, you will need to rely entirely on the serial number and model codes printed on the hardware.
The most critical step is checking the model numbers and serial number, as these are the definitive markers of inclusion in this recall. Check the original product packaging first; the model number should be printed there. The specific models included in this recall are SOR52001 and 7400579. Additionally, if you purchased a kit that includes part number SORJ53101, the ROMEO5 sight is included in that bundle as well. If the original box is no longer available, you must turn your attention to the physical unit.
To find the serial number, you need to access the bottom of the sight. The recall notice explicitly states that Sig Sauer will provide instructions on how to locate this number, but generally, this involves removing the battery cover or accessing the underside of the optic where manufacturing codes are etched or printed. Look closely at the last digit of this serial number. The recalled units are identified by having either the letter "K" or the letter "M" as the very last character in that sequence. If your serial number ends in any other letter or digit, it is not part of this specific recall.
Please note that all recalled dot sights are black in color and come with one CR2032 button cell battery pre-packaged. There were no reported incidents at the time of this notice, but the potential for harm is severe due to the ingestion risk. Therefore, do not guess. If you have any doubt about whether your serial number matches the criteria (ending in K or M) or if your model number does not match SOR52001, 7400579, or the part included in SORJ53101, contact SIG SAUER directly. They are prepared to help you verify your unit’s status before you take any further action.
