An avid environmentalist and hunter, guns have been a part of Busch's life since he was a child.
"It's something you never forget being able to be in the outdoors with your father," Busch said in a 2005 interview with KSDK.
Busch, whose great-grandfather founded Anheuser-Busch, made clear his position on guns and the people who legally use them.
"Hunters put back everything they take out and more," he said at the time.
"...I fail to see how the NRA can disregard the overwhelming will of its members who see background checks as reasonable," Busch writes.
"I am simply unable to comprehend how assault weapons and large capacity magazines have a role in your vision," he said. "The NRA I see today has undermined the values upon which it was established. Your current strategic focus clearly places priority on the needs of gun and ammunition manufacturers while disregarding the opinions of your 4 million individual members."
