While Wisconsin does not have explicit state laws banning binary triggers, federal regulations and interpretations by the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) play a significant role in determining their legal status. Understanding these overlapping laws is crucial for residents and visitors alike.
