Florida gun owners

are suing the state over its new “bump stock” ban, claiming it’s unconstitutional.

TALLAHASSEE — Gun owners have filed a second lawsuit against the state over gun-related provisions in a new school-safety law, this time alleging that a ban on “bump stocks” is an unconstitutional taking of property.

The case, filed last week in Leon County Circuit Court, asks a judge to order “full compensation” for what the plaintiffs’ attorneys estimate are “tens of thousands, or more” Floridians who own bump stocks or similar devices. The ban on bump stocks, which make semi-automatic weapons fire faster, was included in a law passed this month in response to the Feb. 14 mass shooting at Marjory Stoneman Douglas High School in Parkland that left 17 people dead and 17 injured.

The law also raised the minimum age to buy a gun from 18 to 21 and imposed a three-day waiting period for purchasing rifles.

Hours after Gov. Rick Scott signed the law, the National Rifle Association filed a federal lawsuit that challenges the Legislature’s decision to require people to be age 21 before purchasing rifles and other types of long guns. The lawsuit accuses the state of violating the constitutional rights of adults between the ages of 18 and 21.

In the complaint in the bumpstock case, lawyers for the plaintiffs argued that the Florida Constitution bars the state from taking private property “except for a public person and with full compensation therefore paid to each owner.”

But Sen. Bill Galvano, RBradenton, who sponsored the bill, said he stands by the prohibition. “At the end of the day, these devices turn semi-automatic rifles into machine guns. A policy decision consistent with the authority of the state has been made that this is not acceptable,” he said.
