At what minimum age can an individual legally own a gun in the United States?

The minimum age for an individual to legally own a gun in the United States is 18. This is established under federal law, specifically the Gun Control Act of 1968, which prohibits the sale of firearms to anyone under 18. However, for the purchase of handguns, individuals must be at least 21 years old. This distinction is important as it reflects the varied regulations on firearm types and ownership across states.

While some states may have additional restrictions or laws that raise the minimum age to purchase firearms or impose stricter regulations, the federal baseline sets 18 as the age for general firearm ownership. Therefore, individuals can own rifles and shotguns at 18, while handguns require the individual to be at least 21.
