The FBI processed a record number of firearms related background checks last year, indicating that more guns were sold in 2015 than in any previous year in American history.

More than 23 million checks were processed through the National Instant Background Check System in 2015, an all time record.

The all time record for yearly sales comes after May, June, July, August, September, October, November, and December 2015 each set sales records for their respective months.

In December the FBI conducted 3,314,394 checks, an increase of more than half a million checks over the previous single month record set in December 2012.
