I did not it see it...
Am I not reading this correctly?? More than 10 rounds, no matter when it was acquired=disposal. Mags that hold no more than 10 rounds and acquired prior to ban = OK
SECTION 24. Said section 131M of chapter 140 of the General Laws, as so appearing, is hereby further amended by striking out, in line 3, the word “1994.” and inserting in place thereof the following words:- 1994; or (ii) a large capacity feeding device that has a capacity of, or that can be readily restored or converted to accept, more than ten rounds of ammunition; or (iii) a large capacity feeding device that such person lawfully possessed before the effective date of this act that has a capacity of, or that can readily be restored or converted to accept, more than seven but no more than ten rounds of ammunition, where such device contains more than seven rounds of ammunition
"Any large capacity feeding device that has or can readily be restored or converted to accept more than ten rounds of ammunition that was legally possessed by an individual prior to the enactment of this act must be sold or otherwise lawfully disposed of within one year of the act’s effective date. Such large capacity feeding devices may only be sold or disposed of to a purchaser authorized to possess such weapons."
According to my interpretation it says nothing about disposing of magazines with a 10 round capacity or less. It's all circular legal bullshit so who knows.
