What is a receiver group?

Explanation:
Receiver group is the internal action that houses the parts responsible for cycling a cartridge—loading, firing, and ejecting. The bolt provides the locking and extraction, the firing mechanism initiates discharge when the trigger is pulled, and the chamber is where the cartridge sits during firing and interacts with the bolt and firing mechanism to complete the cycle. Those components stay inside the receiver assembly. The other options describe external parts like stock, sights, barrel, muzzle, or grip/guard, which are not part of the receiver’s action. Therefore, the set that includes the bolt, chamber, and firing mechanism best identifies the receiver group.
