Colorado Hunter Education Practice Exam

Which part of a firearm loads, fires, and ejects shells or cartridges?

1. The action

2. The barrel

3. The stock

4. The trigger

The correct answer is: The action

The action is the mechanism inside a firearm that loads, fires, and ejects shells or cartridges. The barrel is responsible for directing the projectile after it has been fired, but it does not perform the actions listed in the question. The stock is the portion of the firearm that is held by the shooter's hands for support and stability, but it does not handle the loading, firing, or ejection of shells. The trigger is responsible for initiating the firing process, but it does not handle the other tasks listed in the question. Therefore, the action is the correct answer as it is the mechanism in the firearm that performs all of the tasks mentioned in the question.
