There was a thread here posted within the last few weeks where a discussion of the legality of telescoping stocks on AR rifles was held. If my memory serves me correctly, a NES moderator said that a telescoping stock could be MA legal if it was pinned permanently in place. Pinning it in one position in effect converts it to a fixed stock in matters concerning MA firearms law. Is this true? I've fallen *hard* for a Bushmaster rifle (AK Carbine) that isn't MA legal. There appears to be a MA-ready version (AK A2) with the 10-round magazine and full buttstock that I'm not crazy about. I could let the A2 follow me home someday soon if it would be legal to swap the stock for a telescoping one fixed in place. Doing so would be a close approximation to the AK Carbine IMO. Do I have a chance with her? I wasn't successful in my attempts to locate the original post. Thus I bring my question to you all. Thanks.
