An AR for example uses a spring loaded plunger on the opposite side of the bolt from the extractor. It is compressed when the round is stripped from the magazine and held compressed until the spent case clears the chamber. It then uses the extractor as a fulcrum and rotates the casing clear of the action.
An AK uses a section of rail on the left side of the receiver as an ejector. The casing is again held by the extractor and after firing this section of rail rotates the casing clear as the bolt travels rearward.
