Which of the following is true about antique firearms?

Antique firearms are defined under federal law as any firearm manufactured before 1899. This definition typically includes muzzle-loading firearms, which are often considered antiques if they were made prior to this date. The significance of this classification is that antique firearms are generally exempt from many of the regulations that apply to modern firearms, making them unique in how they are treated by law. This distinction emphasizes the historical and collectible value of these older firearms, rather than their practical use in sport shooting or other modern applications.

In contrast, modern replicas made after 1900 would not fall under the category of antique firearms, as they do not meet the criteria established by law. Similarly, antique firearms do not have to be stored at a gun range, and they can indeed be used for sport shooting, depending on local laws and regulations. Thus, the characterization of antique firearms as muzzle-loading firearms made before 1900 accurately reflects their legal definition and historical context.
