A 20-year old Oregon man is suing Dick's Sporting Goods (DKS) and Wamart (WMT) after the company raised the legal age to purchase weapons at the retailers to 21 years old in the wake of the school shooting in Parkland, FL in February.

Tyler Watson says he is being discriminated against due to the new policy after attempting to buy a .22-caliber Ruger rifle on Feb. 24 from a Field and Stream store -- a Dick's subsidiary.

"While we haven't seen the complaint, we will respond as appropriate with the court," a Walmart spokesman told local newspaper the Oregonian.

Walmart and Dick's changed their store policies shortly after the Feb. 14 shooting at Marjory Stoneman Douglas High School, which left 17 people dead. 

Watson's attorney said that he was not part of some sort of national movement and that he "was really just trying to buy a rifle.  He didn't know about the policy when he went into" the Field & Stream store, the Oregonian quoted him as saying.
