Will Michaels of Homer, La., examines a Bushmaster M4 A3 Carbine 300 AAC Blackout rifle at the Bushmaster exhibit during the Shooting Hunting Outdoor Tradeshow, Tuesday, Jan. 15, 2013, in Las Vegas. Michaels, who owns a sporting goods store, said while his gun sales focus primarily on bolt action hunting rifles, he and his clients have taken an interest in assault rifles over the last five years because of an expanding wild hog problem in his region. The National Shooting Sports Foundation was focusing its 35th annual SHOT Show on products and services new to what it calls a $4.1 billion industry, with a nod to a raging national debate over assault weapons.
