That means the frenzied market of the Obama years was fueled by people who own multiple guns. According to a study by Harvard and Northeastern universities, 3 percent of the nation’s gun owners own half the private arsenal, averaging 17 guns each.

According to John's Gun Shop's Breunig, those buyers are still buying. He said sales of assault-style weapons fell precipitously after Trump’s election, but some collectors are still looking for specialized firearms.

“They’re spending bigger bucks for more bells and whistles for AR-15s and AR-10s,” he said. “You might have a guy that owns 20 of them, but he’s got to have one more fixed up just the way he wants it. They don’t want the cookie-cutter variety gun, they want extra special and they’re spending a lot of money on triggers and good quality barrels.”

While rifle sales have fallen off, at least in Wisconsin handgun sales are steady. According to the state Department of Justice, the number of concealed carry licenses rose by 45,189 last year, a 16 percent increase over 2016. And requests to the state handgun hotline requesting federal background checks on prospective buyers numbered 147,917 in 2017, about 5 percent down from 2016 but more than any other year since 2012.
