Walmart is restricting the sale of firearms and ammunition to anyone 21 years old and over, according to the Associated Press.
Walmart stopped selling high-powered semi-automatic rifles with high-capacity magazine capabilities in 2015. The major retail store still offers ammunition and other firearms.
Dick's Sporting Goods recently announced it would stop selling semi-automatic rifles and high-capacity magazines. The sporting goods store also raised the age to buy a gun at its locations to 21.
