Massachusetts NFA Laws

Massachusetts bans civilian possession of all four major NFA item categories. M.G.L. c. 140 §§ 121-131 define and prohibit machine guns (which includes full-auto and in some attorney interpretations certain burst-fire configurations), and the state bans 'assault weapon' configurations that overlap with SBRs. Suppressors (called 'silencers' in state statute) are banned. These restrictions operate independently of federal NFA compliance.
