The National Firearms Act (NFA) of 1934 and the Gun Control Act (GCA) of 1968 form the backbone of federal firearms regulation in the United States. While the GCA focuses on general firearm commerce and prohibits certain individuals from possessing guns, the NFA imposes stricter controls on specific “Title II” items like suppressors, short-barreled rifles, machine guns, and destructive devices through taxation and registration. Both frameworks require background checks to ensure compliance with federal prohibitions, but their processes differ in scope, depth, and execution. This article explores these processes, highlights key differences, and details the uniform standard of approval, incorporating relevant statutes and recent developments as of September 2025.
Under the GCA, background checks are primarily conducted through the National Instant Criminal Background Check System (NICS), administered by the FBI. This system verifies whether a prospective buyer is prohibited from possessing firearms before a transfer can occur.
The process begins when a buyer visits a Federal Firearms Licensee (FFL), such as a gun dealer. The buyer completes ATF Form 4473 (Firearms Transaction Record), providing personal information and certifying they are not a prohibited person. The FFL then contacts NICS—typically via phone, online, or point-of-sale system—to initiate the check. NICS cross-references the buyer’s details against federal databases, including criminal history, mental health records, and immigration status.
Responses from NICS fall into three categories:
Timelines are designed for speed, often resolving instantly, but delays can extend up to three days under the Brady Handgun Violence Prevention Act. No fingerprints or photographs are required for standard GCA checks, making it a name-based system.
In 2025, ATF expanded the list of state-issued permits (e.g., concealed-carry licenses) that qualify as alternatives to NICS checks, allowing FFLs to bypass the federal system if the permit was issued within five years and involved its own background check. This policy, part of ATF’s “New Era of Reform,” affects general firearm transfers by accepting permits from additional states like Alabama, Michigan, and Indiana, potentially streamlining sales but raising concerns about consistency in prohibiting prohibited persons.
The NFA process is more intensive, as it involves not just a background check but also registration and taxation of regulated items. To make or transfer an NFA item, applicants submit ATF Form 1 (for making) or Form 4 (for transfers). Individuals provide fingerprints (on FD-258 cards), a 2×2 photograph, and notify their Chief Law Enforcement Officer (CLEO). For trusts or entities, “responsible persons” must undergo similar scrutiny per ATF Rule 41F (effective 2016).
The ATF reviews the application, conducts a fingerprint-based background check through NICS and other databases, and verifies no prohibitions exist. This manual process ensures deeper scrutiny, reducing errors from name-based matches alone. Upon approval, a $200 (soon to be $0.00) tax stamp is issued, allowing possession.
Processing times have improved significantly with electronic submissions (eForms). As of July 2025 data, average times include:
Median times for individual eForm 4s reached as low as 4 days, reflecting system upgrades and wider eForm adoption. The 2025 policy on state permit alternatives also applies to NFA transfers, potentially exempting NICS if a qualifying permit is held, though the full ATF approval process remains required.
While both use NICS for core verification, the NFA process is tailored for higher-risk items. The following table outlines the main distinctions:
| Aspect | GCA (Title I Firearms) | NFA (Title II Items) |
|---|---|---|
| Forms | ATF Form 4473 | ATF Form 1/4, plus fingerprints/photos |
| Check Type | Name-based, automated | Fingerprint-based, manual review |
| Timeline | Instant to 3 business days | 4–112+ days (improved with eForms in 2025) |
| Additional Steps | ID verification only | CLEO notification, $200 (soon to be $0.00) tax, registration |
| When Performed | At point of sale | Pre-approval before possession |
| 2025 Updates | More state permits bypass NICS | Faster eForm processing; permit alternatives apply |
These differences stem from the NFA’s emphasis on registration, making it slower but more thorough. For bundled transfers (e.g., a suppressor on a pistol), a separate Form 4473 and NICS check is still be needed for the GCA component.
The standard for approval is identical under both laws: the applicant must not be a “prohibited person” as defined in federal law. This ensures consistency, with no additional NFA-specific criteria beyond GCA prohibitions. Approval is granted if no disqualifiers are found; denials can be appealed through NICS.
Key statutes governing these processes include:
These statutes, amended over time (e.g., by the Firearm Owners’ Protection Act of 1986), integrate to prevent prohibited possession.
The GCA and NFA background check processes serve the same goal—preventing firearms from reaching prohibited individuals—but differ in rigor and procedure to match the regulated items’ nature. With 2025 enhancements like faster eForms for NFA and expanded permit alternatives, efficiency has improved, though core safeguards remain.
