I know this has probably been beat to death, but i cant find a thread specifically on this subject. Can someone tell me if A "new" Steyr AUG is legal in Mass, As long as I change the muzzle device?? Long story short, a seller on gunbroker denied me of the sale, he said it's banned by name along with all duplicates and copies of the Steyr AUG. What pissed me off was the fact that he called My home town firearms officer and some gunshops in Mass to confirm, and of course they said No.
