The manufacturing boom has come in the face of the president’s push to expand background checks and place new restrictions on guns in the wake of high-profile shootings like the recent mass-killing in Charleston, S.C., and the 2012 massacre at a Newtown, Conn., elementary school.

The numbers paint a picture of gun owners who are concerned about new restrictions on their Second Amendment rights, activists say.

“The ATF report confirms what we already know, that Barack Obama deserves the ‘Gun Salesman of the Decade’ award,” said Erich Pratt, spokesman for the Gun Owners of America. “People have been rushing to buy firearms because they’re afraid that Obama will take away their Second Amendment rights.”

The ATF’s annual firearms commerce report tracks the number of guns manufactured in the United States, which provides an indication of gun sales around the country.
