Universal background check
Background checks for private sales of firearms in the United States / From Wikipedia, the free encyclopedia
This article is about background checks for private sales of firearms in the United States. For background checks in general, see Background check.
Proposals for universal background checks would require almost all firearms transactions in the United States to be recorded and go through the National Instant Criminal Background Check System (NICS), closing what is sometimes called the private sale exemption. Universal background checks are not required by U.S. federal law, but at least 21 states and the District of Columbia currently require background checks for at least some private sales of firearms.
