This is the third company to relocate to South Carolina this year in the wake of calls for increased gun control nation-wide. While federal laws remain largely unaltered, gun control advocates were able to push for new laws in several states including New York, which passed the controversial SAFE Act.

“This move to South Carolina will help ensure a solid foundation for our company,” said Tony DiChario, ATI’s president. “The relocation process will be smooth and we have ensured that the process will not affect customer service, product distribution or any other segment of our business. The people of South Carolina have welcomed ATI with open arms and we are excited about making our new corporate home there.”
