They tried this crap when I lived in California years ago.
City ordinances at that time were struck down by the courts who said only the state government could make such laws, not cities, municipalities or county governments.
Don’t know if the same situation would apply to the People’s Republic of Massachusetts.
I know that most of the rules apply to the entire state. Except Boston. They have more stringent rules.

The state has preemption on laws regulating firearms possession. The cities are slowly doing an end around by individual cities banning mags over 10 rds and imposing restrictive storage requirements. Not quite as bad as DC was but close. Storage and mag restrictions have been ruled as permissible by cities. Sunnyvale, San Francisco, and Los Angeles are few examples
