Looks like she blinked on our being felons. However, still no clarification on whether this covers all semi-auto's and also is it legal to transfer the newly minted pre ban rifles

From the MASS.gov FAQ’s

Q: What if I already own a gun that is a copy or duplicate?
•If a weapon is a copy or duplicate of one of the models enumerated in the law, it is an Assault weapon. The Enforcement notice will not be applied to possession, ownership or transfer by an individual gun owner of weapons obtained on or before July 20, 2016.
•The AGO also will not enforce the law against a gun dealer that possesses or transfers a “copy or duplicate” weapon that was obtained on or before July 20, 2016, provided that transfers, if any, are made to persons or businesses in states where ownership of the weapon is legal.
