Massachusetts Gun Laws in Plain English
In Massachusetts, you must have a state license (LTC or FID) to buy or even touch a gun or ammunition. You cannot own most AR-15s or magazines that hold more than 10 rounds unless they are very old. You must store your guns locked up at all times when not in use. Carrying a concealed weapon requires a license that involves a background check, interview, and training.
Critical: Massachusetts Gun Law Gotchas
These are the most important things to know that could get you arrested or charged with a crime:
- #1Possessing a single spent shell casing in your car without a valid LTC/FID is a crime (M.G.L. c. 140, § 129C).
- #2The 'Glock Gap': You can own a Glock if you find one in state, but dealers cannot sell you a new one because it violates AG consumer protection regs (940 CMR 16.00).
- #3Post-1994 magazines holding 11+ rounds are felonies to possess. The burden is often on you to prove a mag is pre-1994 (M.G.L. c. 140, § 131M).
- #4Non-residents cannot bring handguns into MA without a temporary non-resident license, even if locked in the trunk, unless strictly passing through under FOPA (no stops).
- #5Leaving a gun in a glass display cabinet or a simple locked closet does not meet the 'locked container' storage requirement (M.G.L. c. 140, § 131L).
- #6If you have an FID (not LTC), you cannot possess 'large capacity' rifles or shotguns, even if they are otherwise legal.
- #7The 2024 Act bans 'Assault Style Firearms' acquired after August 1, 2024. If you move to MA with one after this date, it is likely illegal.
- #8Flash hiders are considered an 'assault weapon' feature on semi-auto rifles with detachable mags. A muzzle brake is okay, but it must be pinned/welded if the barrel is threaded.
- #9You cannot buy a handgun in another state and bring it back yourself; it must be shipped to a MA dealer.
- #10Open carry of a handgun with an LTC is legal by statute but can lead to license revocation for 'unsuitability' if police receive complaints.
- #11Stun guns require a license (LTC/FID) to possess.
- #12If you are denied a license, you must surrender all firearms immediately to the police.
- #13The federal 1,000-foot Gun-Free School Zone applies to you unless you have a MA LTC; an FID does not exempt you.
