An analysis of background check numbers by industry analyst Small Arms Analytics & Forecasting released on Wednesday indicates that more than 2.3 million guns were sold in the United States during June. That’s an increase of more than 145.3 percent over June 2019. It’s also up from the 1.7 million estimated to have been sold in May, the 1.8 million in April, and just shy of the all-time monthly record of 2.5 million set back in March.

There have now been an estimated 8.3 million firearms sold in the United States since March—a record-setting pace likely to make 2020 the greatest year for gun sales in American history if the trend continues.

Gun and ammunition retailers are having trouble keeping up with the demand as Americans flood stores.
