Neil Heslin, the father of a 6-year-old boy who was murdered at Sandy Hook Elementary School last month, said Tuesday night he wasn't particularly troubled by gun advocates at a recent legislative hearing.

During the hearing on Monday, Heslin asked why Americans needed "to have one of these assault-style weapons or military weapons or high-capacity clips?" Several gun advocates shouted about the Second Amendment in response. Those who shouted were admonished by the chairman, who threatened to clear the floor.

"It didn't really phase me," he told CNN's Piers Morgan. "It was no more or no less than I would have expected. It wasn't the answer to my question."

Heslin said he supported the Second Amendment, but believed that assault weapons and high-capacity magazines should be restricted. He also supported universal background checks on gun purchases.

"I am in support of the Second Amendment and I think people do have the right to bear arms and have guns."
