The family of the inventor of the AR-15 speaks:
"Our father, Eugene Stoner, designed the AR-15 and subsequent M-16 as a military weapon to give our soldiers an advantage over the AK-47," the Stoner family told NBC News late Wednesday. "He died long before any mass shootings occurred. But, we do think he would have been horrified and sickened as anyone, if not more by these events."

"What has happened, good or bad, since his patents have expired is a result of our free market system," Stoner's family said. "Currently, a more interesting question is 'Who now is benefiting from the manufacturing and sales of AR-15s, and for what uses?'"
