New York Firearms Safety Course Practice Exam

Which part of a firearm is critical for ensuring the ammunition fires correctly?

1. The stock

2. The muzzle

3. The action

4. The barrel

The correct answer is: The action

The action is the correct answer because it is responsible for loading, firing, and extracting the ammunition. The stock is the part of the firearm that the shooter holds, and while it can affect the accuracy of the shot, it is not critical for ensuring the ammunition fires correctly. The muzzle is also not the correct answer as it is simply the opening at the end of the barrel where the bullet exits. The barrel is responsible for guiding the projectile, but it does not directly impact the firing of the ammunition. Therefore, the most critical part of the firearm for ensuring the ammunition fires correctly is the action.
