Two major U.S. retailers changed their gun sales policies Wednesday in the fallout over a Florida high school massacre.

Walmart, the country's biggest retailer, announced it is raising the age restriction for buying guns and ammunition to 21.

"We take seriously our obligation to be a responsible seller," it said in a statement.

Walmart is also dropping toys and other items that resemble assault-style weapons from its website. The retail giant stopped selling assault-style guns in 2017 and does not sell handguns except for its stores in Alaska.

Earlier Wednesday, Dick's Sporting Goods announced it would no longer sell assault-style rifles or any gun to anyone younger than 21.

The chain went one step further and urged Congress to ban assault-style weapons and raise the minimum age.

Both Walmart and Dick's say they are committed to serving sportsmen, hunters, and the majority of gun owners whom they call law-abiding citizens.

The mass shooting of 17 people at Marjory Stoneman Douglas High School has had an impact on the corporate world, which is seemingly taking a close look at nationwide polls that overwhelmingly favor tighter gun laws.
