Kelly said he bought the AR-15 to show how easy it is to buy a weapon with high-capacity magazines even with a background check. He planned to surrender the gun to Tucson police, Politico reported.
Doug MacKinlay, owner of Diamondback Police Supply, said he canceled the purchase of the rifle when he discovered Kelly didn't intend to use it.
"While I support and respect Mark Kelly's 2nd Amendment rights to purchase, possess, and use firearms in a safe and responsible manner, his recent statements to the media made it clear that his intent in purchasing the Sig Sauer M400 5.56mm rifle from us was for reasons other then for his personal use," MacKinlay wrote on Facebook Monday. "In light of this fact, I determined that it was in my company's best interest to terminate this transaction prior to his returning to my store to complete the Federal Form 4473 and NICS background check required of Mr. Kelly before he could take possession this firearm."
Giffords suffered a traumatic head injury Jan. 8, 2011, when Jared Loughner, a community college student, opened fire at a meet-and-greet outside a Tucson supermarket. She and her husband, a Navy officer and NASA shuttle commander, have founded Americans for Responsible Solutions, a group that pushes for expanded background checks for gun buyers.
