Received a letter today from the Commonwealth of Massachusetts advising
all gun license holders on record that as of February 1, 2018
the purchase, sale or offering for sale of a bump stock or trigger crank
is unlawful.

Furthermore, effective after 90 days of February 1, 2018, the new law
makes possession of either, regardless of what type of license you have
unlawful, including possession in a private home. Even if you hold a
machine gun license, bump stocks and trigger cranks are illegal to own
after the 90 day period.

The letter goes on to state that if you have either of these devices you
are required by law to contact your local police department or the
Massachusetts State Police to arrange to transfer them for destruction
by the police.

Retention of either beyond the 90 day period will expose the owner to
criminal prosecution.
