The world’s largest retailer will replace rifles, which are sold at about one third of its U.S. stores, with shotguns and other hunting weapons. Quartz reported the news earlier.

“There wasn’t a whole lot of demand for those products so we replaced them with products we have seen customers coming into purchase it,” Walmart spokesman Kory Lundberg told Fortune. Within the next two weeks, MSRs (modern sporting rifles) shouldn’t be in any more Walmart stores.

Walmart, the single largest seller of guns and ammunition, has often come under criticism from gun control advocates for selling these items, particularly after high profile incidents such as the 2012 massacre of school children in Newtown (where the killer used an AR-15), Connecticut.

The move by Walmart comes as firearms makers struggle with declining sales: Remington Outdoor Group last week reported that its sale of firearms fell 13.3% in the first half of the year, while Smith & Wesson’s overall sales saw a 12% drop. Sales often spike when gun enthusiasts believe there will be tighter gun laws put in place, then often slip when those concerns pass.
