|Subject/Law||Long Guns||Handguns||Relevant Statutes||Notes|
|State permit required to purchase?||Yes||Yes||MA Ch. 140 Sec. 129C||Firearm Identification (FID) or license to carry required.|
|Firearm registration?||No||No||Although registration is not specifically required by law, transfers of firearm ownership are required to be recorded with the Massachusetts Executive Office of Public Safety and Security (EOPSS): by the seller if in state, or by the buyer if out of state. The Massachusetts EOPSS also provides the option to register a firearm, although, other than obtaining a firearm from out of state (a transfer of ownership), this is not required by law.|
|Owner license required?||Yes||Yes||MA Ch. 140 Sec. 129C||Firearm Identification (FID) or license to carry required.|
|License required for concealed carry?||N/A||Yes||MA Ch. 140 Sec. 131||Massachusetts is a "may issue" state for carry; the issuing authority must provide written explanation for the denial of any application, which is subject to appeal. The issuing authority is the local police chief for most jurisdictions, who has discretion in issuing carry licenses based on an applicant's suitability and stated need. In most jurisdictions, applicants who pass a background check and complete required training are issued licenses, but the issuing authority may impose varying degrees of restriction on the license (e.g., hunting, carry to/from a range, firearms dealer, or gunsmith, only while on-duty (for security professionals), etc.). Towns closer to large cities (like Boston) are de facto restricted, whereas more rural (and some suburban) towns are more inclined to issue unrestricted licenses. Permits are valid statewide, provided the license-holder complies with restrictions (if any) imposed by the issuing authority.|
|License required for open carry?||N/A||Yes||An individual with a Class A unrestricted license to carry firearms (LTC-A) does not have to conceal a handgun in public. Moreover, in 2013, the Massachusetts Supreme Judicial Court ruled that the holder of a LTC-A license is not responsible for alarm caused by licensed carry of a handgun, and that a permit cannot be revoked for suitability purposes under these circumstances.  If police demand to see the permit, it must be produced, per G.L. c. 140, § 129 (c). Failure to produce a LTC upon demand by law enforcement is probable cause for arrest. Open carry of long guns is prohibited, except while hunting.|
|State preemption of local restrictions?||No||No||There is limited preemption for some laws.|
|Assault weapon law?||Yes||Yes||A two point "banned features" system is what defines an assault weapon. These assault weapons are prohibited unless lawfully owned on or prior to September 13, 1994. Firearms that do not have two or more "banned features" are legal to purchase with an LTC or in some cases a standard FID so long as magazine restrictions are followed to what your license allows.|
|Magazine Capacity Restriction?||Yes||Yes||MA Ch. 140 Sec. 121||Illegal to possess magazines of over 10 rounds capacity. Pre-ban magazines manufactured before September 13, 1994 are exempt from this restriction.|
|NFA weapons restricted?||Yes||Yes||MA Ch. 140 Sec. 131||Suppressors are restricted only for law enforcement or licensed manufacturers. Some destructive devices are banned at the state level, while others are banned at a local level. DD's can be completely illegal or legal depending on what town you live in. SBR's, SBS's, and AOW's are allowed with proper approval from the ATF. A machine gun license is required to possess a machine gun.|
|Background checks required for private sales?||Yes||Yes||MA Ch. 140 Sec. 128A||The seller must verify the buyer's Firearm Identification Card with the Department of Criminal Justice Information Services.|
|Red flag law?||Yes||Yes||A judge may issue an order to temporarily confiscate the firearms of a person who appears to be at risk of harming themselves or another person.|
Massachusetts Law requires firearm owners to be licensed through their local Police Department or the Massachusetts State Police if no local licensing authority is available. A license is required by state law for buying firearms and ammunition. An applicant must have passed a State approved firearm safety course before applying for a license.
All applications, interviews, fees, and fingerprinting are done at the local Police Department then sent electronically to the Massachusetts Criminal History Board for the mandatory background checks and processing. All approved applicants will receive their license from the issuing Police Department. All licensing information is stored by the Criminal History Board. Non residents who are planning on carrying in the state must apply for a temporary license to carry (LTC) through the State Police before their travel.
As of January 1, 2015, Massachusetts will no longer issue A and B Licenses to Carry, there will be just a single LTC which is identical to the old LTC-A.
- FID (Firearms Identification Card): Permits the purchase of rifles and shotguns with a capacity of no more than 10 rounds and their carrying for hunting and sporting purposes.  FIDs are "Shall issue," except if the applicant fails a background check or is deemed "unsuitable" by the Police Chief.
- LTC-A: This license allows purchase any firearm legal in the Commonwealth of Massachusetts, are authorized to own "large capacity" firearms holding greater than 10 rounds assuming the magazine is "pre-ban" (Manufactured prior to September 13, 1994) post ban high-capacity magazines are not legal in Massachusetts with the exception of Law Enforcement. An LTC-A is the only permit that allows concealed carry in Massachusetts assuming it has not had any restrictions placed on it by the Chief of Police or issuing authority.
- LTC-B: This license allows purchase/possession of all high capacity rifles/shotguns and standard (not high) capacity handguns. One may only purchase/possess handguns that are not on the Large Capacity Weapons Roster, nor in the presence of a magazine with a capacity of greater than 10 rounds. Handguns must be transported unloaded and locked in a case at all times with this license; no CCW is permitted. This license is no longer being issued as of 2015.
- "Machine gun" license: A machine gun license, granted on a may-issue basis, is required to purchase/possess a machine gun. Issuance is at the discretion of the police chief of the city or town, and criteria vary widely. Machine gun licenses are generally only issued to collectors (C&R FFL holders) and police instructors.
Additionally, LTC permits may have the following restrictions, however, none of these restrictions have been clearly defined by state law, and are subject to each Chief of Police's definition of such. Violation of the restrictions imposed by the licensing authority shall be cause for suspension or revocation of the license and a fine of $1,000 to $10,000. 
- Employment: restricts possession to business owner engaged in business activities or to an employee while engaged in work-related activities, and maintaining proficiency, where the employer requires the carry of a firearm (i.e. armored car, security guard, etc.). Includes travel to and from activity location.
- Target and hunting: (Most Common restriction)– restricts possession to the purpose of lawful recreational shooting or competition; for use in the lawful pursuit of game animals and birds; for personal protection in the home; and for the purpose of collecting (other than machine guns). Includes travel to and from activity location
- Sporting: restricts possession to the purpose of lawful recreational shooting or competition; for use in the lawful pursuit of game animals and birds; for personal protection in the home; for the purpose of collecting (other than machine guns); and for outdoor recreational activities such as hiking, camping, cross-country skiing, or similar activities. Includes travel to and from activity location.
- Other: (Very Rare) Issuing Chief has special reason or direction for the restriction of the permit. Can vary greatly.
Assault weapons are defined (with no exceptions, except pre 1994 models) as: (i) Avtomat Kalashnikov (AK) (all models), Action Arms Israeli Military Industries UZI and Galil, Beretta Ar70 (SC-70), Colt AR-15, Fabrique National FN/FAL, FN/LAR and FNC, SWD M-10, M-11, M-11/9 and M-12, Steyr AUG, INTRATEC TEC-9, TEC-DC9, TEC-22, revolving cylinder shotguns, Street Sweeper, and the Striker 12.
Assault weapons are also defined as:
- A semiautomatic, centerfire rifle that has the capacity to accept a detachable magazine and any two of the following:
- A pistol grip that protrudes conspicuously beneath the action of the weapon.
- A folding or telescoping stock.
- A grenade launcher or flare launcher.
- A flash suppressor or threaded barrel designed to accommodate a flash suppressor;
- A bayonet lug
- A semiautomatic pistol that has the capacity to accept a detachable magazine and any two of the following:
- A threaded barrel, capable of accepting a flash suppressor
- A second handgrip.
- A shroud that is attached to, or partially or completely encircles, the barrel that allows the bearer to fire the weapon without burning his or her hand, except a slide that encloses the barrel.
- The capacity to accept a detachable magazine at some location outside of the pistol grip.
- A semiautomatic shotgun that has two of the following:
- A folding or telescoping stock.
- A pistol grip that protrudes conspicuously beneath the action of the weapon.
- A fixed magazine capacity in excess of 5 rounds
- The ability to accept a detachable magazine.
- Any shotgun with a revolving cylinder.
A license to possess or carry a machine gun may be issued only to a firearm instructor certified by the Criminal Justice Training Council for the sole purpose of firearm instruction to police personnel, or to a bona fide collector of firearms upon application or renewal of such license.
A "bona fide collector of firearms," for the purpose of issuance of a machine gun license, shall be defined as an individual who acquires firearms for such lawful purposes as historical significance, display, research, lecturing, demonstration, test firing, investment or other like purpose.
For the purpose of issuance of a machine gun license, the acquisition of firearms for sporting use or for use as an offensive or defensive weapon shall not qualify an applicant as a bona fide collector of firearms.
All private sales are required to be registered through an FA-10 form with the Criminal History Board, Firearm Records division. The state has an assault weapons ban similar to the expired Federal ban. Massachusetts is a " may issue", as such the LTC-A is issued in a discretionary manner.
While Massachusetts' firearms laws are some of the most strict in the United States, they are not applicable to travelers who comply with the Firearm Owners Protection Act's traveler's exemption.  
Unless carried or under the control of the owner, state law requires all firearms to be stored in a locked container, or equipped with a tamper-resistant mechanical lock or other safety device (see trigger lock), properly engaged so as to render such weapon inoperable by any person other than the owner or other lawfully authorized user. If in a vehicle, firearm must be unloaded and contained within the locked trunk of such vehicle or in a locked case or other secure container, unless the licensee has a Class A license, in which case the firearm must be under the licensee's direct control. Any firearms that are found to be unsecured may be confiscated by law enforcement officers and license may be revoked. In the event a license is revoked for any reason, law enforcement will confiscate all weapons and store them for 1 year before destroying them unless the revoked licensee transfers ownership to a properly licensed party who then claims the firearms. Also, gun license holders may encounter licensing issues when moving from one town to another. While one city or town police chief may have issued a license, the chief of police in the city or town where the license holder may move does not have to authorize it, and may require that guns be surrendered. If a gun license is not authorized, and the police determine that the resident also holds a license in a different state, they may contact law enforcement in that state and inform them of the action, which could lead to the loss of the out-of-state license as well.
Aliens who reside in Massachusetts can apply for a "permit to possess non large capacity rifles and shotguns pursuant M.G.L. 140 s. 131H" directly with the Massachusetts Firearms Record Bureau. The applicants must receive firearms education at the FID or LTC-level and pass a 20-fingerprint FBI background check and interview. This permit is a "may issue" document similar to the FID but expiring December 31 of each year. The procedure requires about 16 weeks from application to delivery of the permit. There is no 90-day grace period for the renewal of alien permits. Both nonresident (i.e. visa-holders) and permanent resident (i.e. green-card holders) aliens are lumped together by Massachusetts law. The alien permit allows the possession of non-high capacity (10 rounds or less) shotguns, rifles, and ammunition. This includes .22 caliber rifles with tubular magazines holding more than 10 rounds, but it excludes high capacity rifles, assault rifles, and handguns. FID and LTC are generally not issued to aliens even though Massachusetts law grants some latitude to the Colonel of Massachusetts State Police, who may be petitioned directly. A recent lawsuit, Fletcher v. Haas, has expanded Massachusetts aliens' gun rights by allowing possession and purchase of handguns for permanent resident aliens (green card holders).  Alien permits are still in existence and required for all non-permanent resident aliens in Massachusetts.
As of April 30, 2012, all lawful permanent resident aliens (green card holders) are eligible to apply for a Massachusetts resident license to carry ("LTC") or firearms identification card ("FID").
Massachusetts enacted a red flag law in 2018. A judge may issue an order to temporarily confiscate the firearms of a person who appears to be at risk of harming themselves or another person. A hearing must be held within ten days of the order being issued. At the hearing, if there is sufficient evidence to substantiate the risk, the person's firearms may be confiscated for up to one year.
