I was thinking a blade type ejector that in fact goes in the receiver. So you seem to be saying it should have a plunger ejector which goes in the bolt ?

Pull your bolt back to the end of its travel and look to see if there is any blade protruding through a slot in the side of the bolt. This is the type of ejector normally used on rimfires. To eject the brass requires that the bolt go all the way to the end of its travel, not just back enough to allow the brass to clear the port.

Pictures of the bolt in the rear most position would help.
