The ejector box is on the left side of the receiver at the rear. It has a flat style spring that functions it. As the bolt completes its travel rearward the ejector is allowed to extend into the slot in the bolt and catches the base of the round. The extractor on the right hand side of the bolt applies pressure and keeps the round in place (controlled) and the rim of the round pivots around the extractor rim and the round then spins out of the ejection cutout.
Thank you both for the explanation.
