Minnesota Firearms Safety Hunter Education Practice Exam

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

1. Barrel

2. Action

3. Stock

4. Trigger

The correct answer is: Action

The correct answer is B: Action. The action is the part of the firearm that loads cartridges into the firing chamber, fires the cartridge by striking the primer, and then ejects the spent cartridge casing after firing. The action of a firearm is crucial for the functioning of the weapon as it controls the entire process of loading, firing, and ejecting cartridges. In contrast, the other options are not directly responsible for these functions: - The barrel is the part of the firearm through which the projectile travels after being fired. - The stock is the rear part of the firearm that is held against the shoulder when shooting, providing support and stability. - The trigger is the mechanism that releases the firing pin or striker to initiate the firing sequence, but it does not directly handle the loading, firing, and ejection of cartridges.
