While I don't want to get into this discussion, don't condemn all of the law in Massachusetts unless you understand them.
I can legally transfer up to four firearms annually to a private citizen, including the AR lowers. I can buy as many handguns, rifles and shotguns every day of the year as long as they're on the list, there are no restrictions on quantity or any waiting period. No, I can't buy ammunition through mail order but I can buy as much as I want from CT, NH, RI, ME, and any other state that surrounds me with the possible exception of NY. Considering I can be in all of those states in about an hour, it's not so bad.
I was able to drive through CT with my long guns and just fill out a registration form to notify the state within seven days. The laws here are different, some might think they are pretty restrictive. I've heard of worse places with waiting periods and from a conversation with my buddy in MI last night, I find it's easier to get a CCW in MA than it is in MI these days.
No it ain't TX or FL but it's far better than CA and NJ, NY, PA, and any number of states that don't allow CCW at all.
Now, back to your argument fellas, by the way.....I could buy those lowers from TAB through an FFL, even in MA. It's not the lower that they have a problem with here, it's the evil suppressor, the evil collapsable stock and the evil bayonet mount...everything else is kosher.........
