Which assembly handles feeding rounds onto the bolt face and moving spent cases to the ejection chute?

Explanation:
The rotor assembly does the work of feeding rounds onto the bolt face and moving spent cases to the ejection chute. It rotates to present each round from the belt to the bolt face and push it into the chamber, while also directing the spent casings away from the bolt into the ejector path as the gun cycles. The bolt and carrier handle locking, extraction, and chambering, but not the feeding and ejection choreography; the base plate provides support and spring housing, and the feed gates guide rounds toward the rotor.
