The Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) is proposing a significant change to US gun policy that would allow licensed dealers to ship firearms directly to in-state residents.This rule requires online identity verification, background checks, and a seven-day waiting period after notifying local law enforcement.The measure could benefit companies like GrabAGun, which Donald Trump Jr.co-owns, positioning it for substantial growth.However, competitors such as physical retail stores may also adapt to the regulations.Industry analysts suggest this change could be one of the most consequential in two decades, potentially driving massive growth in online gun sales.Critics, including gun-control advocates, warn that direct shipping increases risks of illegal trafficking, mail theft, and straw purchases.While Trump Jr.denies involvement in the proposal, the debate highlights tensions between regulatory changes and public safety concerns.
