The student activists who survived the Parkland high school massacre released a sweeping gun control plan Wednesday aimed at slashing firearm deaths in the US — including a call to ban assault-type rifles.

The “Peace Plan for a Safer America” also calls for creating a national licensing and gun registry, banning high-capacity magazines, instituting a mandatory gun buyback program and naming a “national director of gun violence prevention.”

March for Our Lives, the group that emerged from the 2018 shooting in Florida that killed 17 people, also calls for raising the minimum age for buying guns from 18 to 21 and requiring a 10-day waiting period for all firearm purchases.

The group’s leaders urged the candidates in the 2020 presidential election to make gun control a priority and included a measure to register more young voters.

“We urge them to take a look at this agenda,” Tyah Amoy-Roberts, a former student who survived the shooting at Marjory Stoneman Douglas High School, said in a statement. “We cannot allow mass shootings in grocery stores, churches, shopping malls, and schools to be the new normal.”

The March for Our Lives plan also calls for a boost in federal funding for gun violence research, which has been limited since 1996 under a law prohibiting the use of federal funds to promote gun control.

The group’s plan comes less than three weeks after 31 people were killed in back-to-back mass shootings in El Paso, Texas, and Dayton, Ohio.

President Trump — a staunch defender of the National Rifle Association and the Second Amendment — reacted to the massacres by voicing support for strengthening the federal background check system.

In recent days, he appears to have softened his stance, saying, “We have very, very strong background checks right now” and focusing instead on the “mental problem” of mass shooters.

But on Wednesday, he firmed up his stance again, saying he does support background checks after Democrats accused him of reversing course.

“I have an appetite for background checks,” the president said from the White House South Lawn as he was departing for an event in Louisville. “We’re going to be doing background checks … We’re going to be filling in some of the loopholes.”

Trump said he wants to get firearms out of the hands of the mentally unstable, adding that he even considers mass shootings a public emergency.

The president confirmed to reporters that he had discussed background checks with NRA chief Wayne LaPierre, but he disputed news reports that he had told LaPierre that background checks were off the table.

The NRA and gun rights supporters blasted the latest effort to restrict guns, which they argue violates the Second Amendment.

“The simple fact remains their proposals and ideas are out of the mainstream and most people will understand their real intent goes beyond what they publicly state,” NRA spokeswoman Amy Hunter said Wednesday.

According to a Reuters/Ipsos poll this month, 69 percent of Americans said they support “strong” or “moderate” firearms restrictions and regulations, including 84 percent of Democrats and 56 percent of Republicans.

March for Our Lives and another gun control group called Giffords — founded by former Rep. Gabby Giffords after she was wounded in a 2011 mass shooting — are planning an Oct. 2 forum for 2020 candidates to discuss gun violence.

David Hogg, 19, a co-founder of March for Our Lives who also survived the Parkland shooting, said: “You see these shootings on TV every day and very little happening around it. It’s painful to watch.

“And I think it’s been really hard for me and many of the other students and people that we work with to find hope in this time,” he said, according to the Washington Post.

“But I think that this plan is something that we can truly — as a country and as Americans united against violence and fighting for peace — can get behind,” he added.
