"We will require all individuals purchasing firearms to be 21 or older," Scott said in a statement on Friday. "There will be exceptions for active duty, reserved military and spouses, national guard members and law enforcement."
The governor also announced a complete ban on the sale of bump stocks, the attachments which enable semi-automatic rifles to fire more rapidly. He did not call for the ban of any specific type of weapon.
The moves signal a new, harsher line on gun laws from the gun-friendly Republican governor. Scott has long enjoyed an A-plus rating from the National Rifle Association and has signed multiple NRA-backed bills.
"I want to make it virtually impossible for anyone who has mental issues to use a gun. I want to make it virtually impossible for anyone who is a danger to themselves or others to use a gun." Scott said.
Other proposals include a $450 million investment in school safety and $50 million in funding for mental health.
The proposals form part of Scott's wider plan to address school safety in the wake of last week's shooting. The attacker, identified as former student Nikolas Cruz, killed 17 students and wounded several others when he opened fire with an AR-15 semi-automatic rifle.
"This killer should not have been able to purchase or even possess a weapon," the governor said. Scott lamented that Cruz was identified by authorities as a potential danger but was still able to legally purchase weapons.

The proposals follow consultation between Scott and the parents, teachers and students of Parkland.
Scott also called for a mandatory law enforcement officer in every public school. There had been an armed deputy on the Stoneman Douglas campus, but he remained outside and did not confront the attacker, the Broward County sheriff said on Thursday.
Federal and state lawmakers have faced renewed calls for tougher action on gun violence in the wake of the high school massacre. Students who survived the shooting at Stoneman Douglas have called for stronger gun control legislation and urged Americans to attend a March for Our Lives" rally in Washington DC next month.
This kid who shot up the Parkland HS purchased his firearm legally which means he passed the FBI background check. Why? Well barring information from law enforcement agencies as to arrests, etc. which are made part of the FBI database, not too much other relevant information is held on anyone. Even sealed & expunged juvenile records do not make it into one's FBI jacket. As to mental health records - well, unless HIPAA is overturned, the FBI would need a signed release from each citizen to obtain their mental health records under the law. Given all that - what more is there to do? Really, if someone wants to go on a killing rampage, they'll do it with whatever "weapon" is available to do the job. If something idiotic like "a gun grab" ever happened, what's to prevent some malicious individual from making an explosive device, mowing people down with large vehicles, etc.? People have been figuring ways out to kill their fellow man since Cain and Abel. Guns or no guns, the killing, unfortunately, will continue.
