The receiver is the largest metal piece of the shotgun, in other words, the frame of the shotgun. All the other parts, such as barrel, stock, bolt, etc- attach to the receiver. With modern firearms, the receiver will be marked with the serial number. Legally, the receiver IS the firearm- all other parts are simply parts.
