A parts kit is a collection of weapon (notably firearm) parts that, according to the Bureau of Alcohol, Tobacco, Firearms, and Explosives (ATF), "is designed to or may be readily be assembled, completed, converted, or restored to expel a projectile by the action of an explosive."[1] As an example, the kit may not include a receiver or include an incomplete receiver. Under current U.S. law, kits that include finished receivers must be serialized and their buyers must receive a background check, but kits that include "unfinished" receivers are totally unregulated for purchase.[2]
