New member, but been lusting after an M1 or M2 for a while. I'm very interested in a 1988 year HK import Benelli M1 Super Sport at a local store near me. Good condition but is missing the choke. The store had quite a few Mobil style chokes that we tried but they all appeared to bottom out on the interior land of the barrel before the choke was fully threaded. I was only able to turn the chokes in about 1.75 turns. Just didn't seem right even though I've only ever used plain bore double barrels.
