FAQ: Handgun Kits & Age Requirements
Q1: Why do I have to be 21 to buy a pistol kit?
A1: Federal law, specifically the Gun Control Act of 1968, requires an individual to be 21 years of age or older to legally purchase a handgun from a Federal Firearms Licensee. The ATF applies this age restriction to kits that are designed to build handguns, such as 80% pistol kits.
Q2: Is an 80% pistol kit considered a handgun?
A2: An 80% pistol kit itself is not legally a handgun because the frame is unfinished. However, because the kit is “readily convertible” into a handgun, federal age restrictions for handguns (21+) apply to the sale of the kit.
Q3: Can I buy a handgun slide at 18?
A3: Yes, under federal law, individual unregulated components like a handgun slide or barrel are not considered firearms and do not have a federal age restriction for purchase. However, a complete kit designed to build a functional handgun is subject to the 21+ age requirement.
Q4: Do I need a background check to buy a handgun kit?
A4: No, you do not need a background check to buy an 80% handgun kit online under federal law, as the unfinished frame is not legally a firearm. The kit can be shipped directly to your home in most states. However, you must comply with all state and local laws, which may be stricter.
Q5: Where can I find the official law on firearm age requirements?
A5: The primary source for federal firearm laws is the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF). Their website, ATF.gov, contains the full text of regulations and frequently asked questions regarding age and eligibility.
