Read the "analysis" that some have done above. They claim (and likely correctly) that this suit and her "promise" of a clarification does not involve ARs specifically, but refers to other guns that some dealers have been selling all along and IIRC the AG's various Emails claimed weren't AWs under her re-interpretation.
So if you are waiting for $50 lowers to be available at dealers in MA again, I'm afraid that you'll have a very long wait.
Personally, I have 4 lowers purchased long before the AG's BS. I'm offering 2 (only one currently posted) in MA before I legally vacate the state. And no, I'm not going to sell them for what I paid for them. I look at this like a neighbor friend who bought a 1966 Mustang for ~$3K, if he were to sell it today he isn't going ot offer it for $3K or even $6K, but price it to the current market. Essentially no more AR lowers are coming into MA thru dealers, so it inflates the price accordingly. If I don't sell them, I'm fine with building them up per plan in NH (I have all the parts, just never assembled the barrels to the uppers).
Very true. Since it is their livelihood on the line, they tend to be very gunshy (pun intended) about what they offer for sale. And the AG isn't going to help them to determine what she's OK with them selling. Every AG since the 1998 law has told dealers to consult with their own lawyer or mfr when queried about what they could legally transfer.
