Wal-Mart will stop selling the AR-15 rifle and other semi-automatic weapons at its stores because fewer people are buying them, a spokesman said Wednesday.

The AR-15 rifles and other modern sporting rifles were being sold at less than a third of the company’s 4,600 U.S. stores. Company spokesman Kory Lundberg said Wal-Mart Stores Inc. will remove the remaining inventory as stores transition from summer to fall merchandise, which should take a week or two to complete.
