Requires applicants for any firearm to wait at least 72 hours before they can receive it. Before this action, Illinois law mandated a 72-hour waiting period to obtain a handgun after purchae, but assault weapons, including the AR-15 and other military-style weapons, could be received in only 24 hours. The governor vetoed a similar bill earlier in the legislative session. This bill is the answer to his proposal within the amendatory veto. Effective January 1, 2019.
