This MCC includes merchants whose primary business is the sale of firearms and ammunition. It is a high-risk category due to the potential for misuse and illegal activities, such as the sale of unlicensed firearms and ammunition. This is one of the first MCCs that is only applied to vendors in certain states, making it critical to understand the merchant's location and jurisdiction.

SafetyKit helps enforce complex regulations surrounding these products, including age verification, licensing requirements, and shipping restrictions that vary by jurisdiction.
