(NYSE:PEW), an online firearms retailer sometimes described as the "Amazon of guns," could benefit from a proposed Bureau of Alcohol, Tobacco, Firearms and Explosives rule that would make it easier for licensed dealers to ship guns directly to buyers’ homes.

ATF Rule Could Reshape Online Gun Sales The rule, if finalized, would mark one of the most consequential changes to U.S. gun policy in two decades and could drive significant growth in online firearm sales, according to a Reuters report that cited industry officials, store owners and gun-control advocates.

The proposal would allow licensed dealers to ship firearms directly to in-state residents who complete online identity verification, pass a background check and wait seven days after local law enforcement is notified.

Current rules generally require online buyers to pick up guns at physical stores and complete in-person checks unless they hold a qualifying permit.
