Whether a ban on AR-15-style rifles and magazines with over ten rounds violates the Second Amendment

This Court has held that arms typically possessed by law-abiding citizens for lawful purposes are protected by the Second Amendment. District of Columbia v. Heller , 554 U.S. 570, 625 (2008). The Second Circuit disagrees. It wrote: “Even assuming arguendo that the desired firearms and magazines are ‘typically possessed’ and ‘in common use’ for lawful purposes, we disagree [that they are necessarily protected by the Second Amendment.]” Pet.App. 30a (emphasis added). The question presented is: Whether a ban on the possession of AR-15-style rifles and firearm magazines with a capacity in excess of ten rounds—both of which are possessed by millions of law-abiding Americans for lawful purposes—violates the Second Amendment.
