Maine Firearm Hunter Safety Course Practice Exam

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

1. Action

2. Stock

3. Barrel

4. Trigger

The correct answer is: Action

The action of a firearm refers to the mechanism by which a round or cartridge is loaded, fired, and ejected. This is achieved through the interaction of multiple moving parts, such as the bolt, hammer, and firing pin. The stock of a firearm is the handle or support that the shooter uses to hold and stabilize the gun, and does not directly affect the loading, firing, or ejecting of shells or cartridges. The barrel of a firearm is the long, metal tube through which the projectile is fired, but it alone does not control the loading or ejection process. The trigger is responsible for initiating the firing of the firearm, but it does not handle the loading or ejection of shells or cartridges. Therefore, the correct answer is A Action.
