President Joe Biden and VIce President Kamala Harris both called for government-mandated buybacks of AR-15s and other semi automatic rifles while campaigning for office.

Biden showed his stance on mandatory buybacks during the first Democrat debate of the 2020 presidential election. 

He said, “Folks, look, and I would buy back [assault]weapons. We already started talking about that. We tried to get it done. I think it can be done. And it should be demanded that we do it. And that’s a good expenditure of money.”

On September 7, 2019, Kamala Harris showed her support for government-mandated buybacks of AR-15s and other semi automatic rifles. Bloomberg quoted Harris saying, “I think it’s a good idea,” while admitting she was unsure how it would be carried out.

On November 19, 2019, NBC News interviewed Harris and she emphasized her support of a “mandatory gun buyback.”

Harris said, “We’ll have an incentive for people to turn them in and [we’ll] buy them back.”

Harris went on to describe AR-15s and other commonly-owned semi automatic rifles as “weapons of war,” and said there were “five million” such rifles in private ownership. 

The National Shooting Sports Foundation reports “there are an estimated 19.8 million Modern Sporting Rifles (MSRs)” that have been in circulation for private ownership since 1990.

That means there are close to 20 million AR-15s, AK-47s, and other variances of both rifles, which legal gun owners would have to hand over to the government if the Biden Administration forced a mandatory buyback.
