The bottom line is the wording of the law is :
b. Render the semi-automatic rifle or magazine inoperable 1or permanently modify a large capacity ammunition magazine to accept 10 rounds or less1;
There are no definitions written out for the “permanently” in the law. There is nothing stated how or what constitutes making it permanent such as riviets, pins, epoxy, blocks, cutting down magbody, etc..
What the state police put out on how to modify mags or what mags are ok, such as Hexmags, is their iinterpretation or guidelines as to what they consider permanent.
As I understand it, the state police does not make law, nor can they add or delete text from the law. They can however, as can your local police, Sheriff, etc, charge you with having a high capacity magazine based on their interpretation of permanently. If that were to happen and you fought it, the decision on permanently would ultimately be made by a judge or jury.. Those of us who are discussing this matter are trying to avoid getting jammed up in the first place.
If anyone knows if there is any case law on this matter, please post it.
