Matt Boggs told Azfamily.com on Thursday that he sold 200 rifles in a few hours under the "Beto Special." He is awaiting more inventory at his Tempe store.
Boggs says he felt compelled to act following O'Rourke's comments during last week's Democratic presidential debate.
O'Rourke said he would take away anyone's AR-15 or AK-47 so it could not "be used against your fellow Americans anymore."
Gerry Hills, president of nonprofit Arizonans for Gun Safety, says business owners like Boggs are putting profits before people's safety.
She says assault rifles serve no real purpose and are "vanity guns."
