It is unlawful to sell, manufacture, purchase, possess or carry any weapon
from which more than one shot may be discharged by a single function of the
trigger, including the frame or receiver of any such weapon.
It is unlawful to sell, manufacture, purchase, possess or carry any
combination of parts designed or intended for use in converting any weapon
into a machine gun, or any combination or parts from which a machine gun
can be assembled.
There is an exception to the above prohibition, providing for the
manufacture, transportation, and sale of machine guns to law enforcement
and military personnel for official purposes, provided such weapons are
“broken down in a non-functioning state or not immediately accessible.”
This prohibition does not apply to persons licensed to manufacture
machine guns or ammunition under federal law and who are actually engaged
in the business of manufacturing such weapons or ammunition, but only with
respect to activities which are in the lawful scope of such business, such as the
manufacture, transportation or testing of such weapons or ammunition.
