Holosun Gun Sight Lawsuit: Easy-to-Swallow Batteries a Danger?

Case Overview: A class action lawsuit alleges Holosun Technologies sold dangerous red and gold dot sights with easily accessible button cell batteries, posing a serious ingestion hazard to children and pets.

Consumers Affected: U.S. consumers who purchased Holosun Red or Gold Dot Sight Models HS503G-ACSS and HE512C-GD from February 2023 through August 2024.

Court: U.S. District Court for the Central District of California

Holosun Technologies, a popular manufacturer of firearm optics, is facing a proposed class action lawsuit alleging it sold dangerous red and gold dot sights without proper safety protections, leaving children and pets at risk of swallowing button cell batteries.

The lawsuit, filed by Fort Worth resident Landry Hart, centers on Holosun’s models HS5036-ACSS and HE5126-GD, which were sold with easily accessible lithium coin batteries. 

According to the complaint, the battery compartment design violates federal safety standards and lacks child-resistant packaging or adequate warnings—issues serious enough to spark a February 2025 recall of nearly 9,400 units.

Holosun Gun Sights Allegedly Pose Ingestion Risk to Children, Pets

Hart says he bought two of the defective sights—one from Amazon, the other from a retail store—for personal use, unaware of the ingestion hazard they posed. The lawsuit claims he would never have made the purchase had he known the risks.

Hart still has the recalled optics and argues that, like other customers, he was promised a safe product. Instead, he says he got a design flaw that could result in “significant injuries, including death” if a child or pet swallows the battery. 

The lawsuit says this made the product "unmerchantable" and unsuitable for its intended use. Hart is seeking damages and injunctive relief to prevent similar safety lapses in the future.

Lawsuit Claims Violation of Federal Safety Standards and Inadequate Warnings

Holosun, founded in 2013, is known for its firearm aiming devices and sells widely through major outlets like Bass Pro Shops and Amazon. The models named in the lawsuit use small button cell batteries to power the reticle, helping users aim precisely.

The legal filing claims Holosun’s products violate Reese’s Law and other federal rules requiring child-resistant battery compartments and warnings about ingestion dangers. The U.S. Consumer Product Safety Commission (CPSC) recalled the affected models earlier this year after confirming the batteries could be accessed too easily.

Battery Safety Concerns Lead to Increased Legal Action Across Industries

The Holosun lawsuit is part of a growing number of legal actions targeting companies over unsafe button battery designs. 

In January, gunmaker SIG SAUER faced a major recall and potential legal exposure after pulling 230,000 of its ROMEO5 red dot sights for similar safety failures—specifically, battery compartments that didn’t meet child-resistance standards and lacked federally mandated warning labels.

Beyond firearm accessories, battery safety has become a flashpoint in lawsuits across multiple industries. Automakers like Ford, Audi, and Volkswagen are battling class action suits over lithium-ion battery defects that allegedly pose fire and explosion risks. In one case, Ford drivers were advised to stop charging their hybrid vehicles altogether after reports of spontaneous battery fires.

Even power tool and e-scooter manufacturers, including Chervon North America and Swagtron, have come under fire for selling products plaintiffs say can overheat or combust. 

In his lawsuit against Holosun Technologies, Inc., Hart wants to represent anyone in the US who purchased a Holosun Red or Gold Dot Sight Models HS503G-ACSS and  HE512C-GD in the from February 2023 through August 2024.
