The "Sporting Firearms Access Act of 2025" aims to reform existing restrictions on the importation of firearms and ammunition into the United States. It specifically amends federal law to broaden the definition of what constitutes a firearm or ammunition "generally recognized as particularly suitable for or readily adaptable to sporting purposes." This expanded definition now explicitly includes items designed for uses such as hunting, recreational target shooting, organized and governed competitions, or civilian rifle match competitions.

The bill introduces a strict timeline for the Attorney General's (AG) determination on import requests. The AG must make a decision within 90 days of a request; failure to do so results in the automatic allowance of the importation. If an application is denied, the AG is required to provide a written basis for the denial and publish it on the Bureau of Alcohol, Tobacco, Firearms, and Explosives website.

A significant provision prohibits the AG from denying the importation of firearms or ammunition that are substantially similar to those already in circulation within the United States. The AG must define "substantially similar" in consultation with various firearms industry representatives, including hunting guides, shooting magazine editors, and trade associations. This definition will also reference existing processes that examine the physical and technical characteristics of firearms.

The legislation establishes a robust appeals process for denied import applications. Aggrieved parties can request a prompt administrative hearing, and if the denial is upheld, they may seek de novo judicial review in a U.S. district court. During judicial review, the Attorney General bears the burden of proof to demonstrate that the firearm or ammunition is not suitable for sporting purposes or not substantially similar to those already in circulation. If the court reverses the denial, it can award reasonable attorney fees to the aggrieved party.
