mine came with what I believe to be the 14 oz. sleeve.This gun has HW-55M stamped on the barrel(although the stock configuration on this gun looks like many HW-55MM model's I've seen)this sleeve also seems to be glued or epoxied on.I was fortunate this gun also came with the factory rubber eyeshade on the rear sight that seems to often be missing from many guns that you see.Got this one from Ingvar Alm from Minnisota about six years ago.( sorry I tried to post pictures with this post but I just can't seem to be able to)
