Maine Firearm Hunter Safety Course Practice Exam

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

1. Stock

2. Action

3. Barrel

4. Trigger

The correct answer is: Action

The correct answer is B - Action. The action of a firearm is the mechanism responsible for loading, firing, and ejecting shells or cartridges. It is essentially the moving parts of the firearm that work together to facilitate the firing process. In contrast, the stock (A) is the part of the firearm that rests against the shooter's shoulder, providing stability and support. The barrel (C) is the part through which the projectile travels, and the trigger (D) is what the shooter presses to discharge the firearm. However, neither the stock, barrel, nor trigger are directly responsible for loading, firing, and ejecting shells or cartridges like the action of the firearm does.
