Caution--Massachusetts has enacted one of the most restrictive gun laws in the nation, imposing a mandatory one-year jail sentence for anyone illegally possessing a firearm, loaded or unloaded, "on his person or under his control in a vehicle." In all cases, all firearms must be transported as prescribed in the general rule.
BOSTON--Under a vague law, it is unlawful to possess, display, transfer or receive any shotgun with a capacity exceeding six rounds; a semi-automatic rifle with a magazine exceeding 10 rounds; any SKS, AK47, Uzi, AR-15, Steyr AUG, FN-FAL, or FN-FNC rifle; any semi-automatic pistol which is a modification of a proscribed rifle or shotgun; and any magazine or belt that holds more than 10 rounds. An "assault weapons roster board" may add additional firearms to the list of "assault weapons." For owners to continue possession of such firearms, a license/registration must have been obtained from the Boston Police Commissioner within 90 days of the effective date of the law (12/ 9/89) or within 90 days of the addition of a firearm to a roster of "assault weapons." Otherwise a license/registration cannot be obtained.
The provision does not apply to possession by nonresidents of Boston at a sporting or shooting club, by a person with a Massachusetts license to carry a pistol, or while taking part in competition or at a collectors` exhibit or meeting or traveling to or from such event or while in transit through Boston for the purpose of hunting by licensed hunters, provided that in all cases the "assault weapon" is unloaded and packaged and the person has a Massachusetts Firearm Identification Card or has a license or permit to carry or possess firearms issued by another state. Prospective travelers are urged to contact the Massachusetts Firearms Records Bureau at (617)660-4780 or the State Police at
