1. Minimum Age for Rifle Purchases
Under current federal law, one must be at least 21 to own a handgun, but to own a rifle or shotgun, the age requirement is 18. Since many of these school shooters have been teens, one suggestion is to raise the age requirement for long guns to match that of handguns.
This proposal is currently under review in the Florida legislature, along with expanding the three-day waiting requirement for handguns to all guns.
Conservative NYT columnist Ross Douthat proposed even more restrictive age requirements.
"Let 18-year-olds own hunting rifles. Make revolvers available at 21. Semiautomatic pistols, at 25. And semi-automatic rifles like the AR-15 could be sold to 30-year-olds but no one younger," he wrote in a Saturday op-ed.
