Universal background check

Currently, federal law requires background checks (through the National Instant Criminal Background Check System) only for guns sold through licensed firearm dealers, which account for 78% of all gun sales in the United States. This figure was published in a 2017 study by the Annals of Internal Medicine which compared data from 1994, indicating 40% of recent gun acquisitions were completed without a background check, to a 2015 survey which found that 22% of recent gun transfers (purchased and nonpurchased) were completed without a background check. The current federal law allows people not ``engaged in the business'' of selling firearms to sell firearms without a license or records. The Coalition to Stop Gun Violence (CSGV) states that the National Instant Criminal Background Check System has prevented over two million felons and other prohibited persons from purchasing firearms. According to the CSGV, the law also has a prohibitive effect, that deters illegal purchases.
