18 USC §§921-931:
Gun Control Act Overview

Title 18, Chapter 44 currently contains Sections 921 through 934.^[1] The Gun Control Act of 1968 created the core federal framework, and later laws added and amended provisions within the chapter.

Structure

Chapter 44 includes Section 921 (definitions), Section 922 (unlawful acts), Section 923 (licensing), Section 924 (penalties), Section 925 (exceptions and relief), Section 925A (a remedy for an erroneous firearm denial), Sections 925B through 925D (reporting and data provisions), Sections 926 through 926C (regulations, interstate transport, and qualified-law-enforcement provisions), Sections 927 through 931, and Sections 932 through 934. The Bipartisan Safer Communities Act of 2022 added Sections 932 through 934, including the straw-purchasing and trafficking offenses.

Key Penalties Under Section 924

• False statements on Form 4473: Up to 10 years
• Section 922(g) violations: Up to 15 years
• Armed Career Criminal Act: 15-year mandatory minimum
• Using/carrying firearm during crime of violence or drug crime (Section 924(c)): 5-year mandatory minimum (consecutive); brandishing: 7 years; discharging: 10 years; machine gun/silencer: 30 years
• Second Section 924(c): 25 years
• Straw purchasing (Section 932): Up to 15 years, or up to 25 years when the purchaser knows or has reasonable cause to believe the firearm will be used to commit a felony, federal crime of terrorism, or drug-trafficking crime. Firearms trafficking (Section 933): Up to 15 years.

Federal-State Relationship

Section 927 states: "No provision of this chapter shall be construed as indicating an intent on the part of the Congress to occupy the field in which such provision operates to the exclusion of the law of any State on the same subject matter, unless there is a direct and positive conflict between such provision and the law of the State so that the two cannot be reconciled or consistently stand together." Congress declined field preemption but kept conflict preemption, so state law is displaced only where obeying both is impossible. Federal law sets a minimum floor. Massachusetts adds mandatory licensing for all possession, universal background checks, an assault-style firearm ban, a complete suppressor ban, mandatory safe storage, a registration system, prohibited carry areas, and broader prohibited persons categories.
