L.L. Bean has joined several other retailers in tightening its restrictions on the purchase of firearms.

The AP reports the Maine-based company has joined Walmart and Dick's Sporting Goods in changing its firearm regulations, in the wake of the Parkland, Florida school shootings. Going forward, customers will need to be at least 21 years old to purchase a gun from L.L. Bean.

Company spokeswoman Carolyn Beem said in a media release that LL Bean only sells firearms at its flagship store in Freeport, and its inventory only includes guns specific to hunting and target shooting. L.L. Bean doesn't carry assault-style rifles, high-capacity, firearms, bump stocks, or handguns of any kind.

The retailers have changed their policies two weeks after 19-year-old Nikolas Cruz killed 17 students and teachers at Marjory Stoneman Douglas High School in Parkland, Florida with an AR-15 rifle.
