California Firearm Safety Certificate (FSC) Practice Exam

Which part of a firearm is responsible for firing the bullet?

1. Barrel

2. Trigger

3. Magazine

4. Scope

The correct answer is: Trigger

The correct answer is the Trigger. The trigger is the part of a firearm that, when pulled, initiates the firing sequence by releasing the hammer or striker to strike the primer of the cartridge, thus firing the bullet. The other options are incorrect because: - The Barrel is not responsible for firing the bullet but rather guides the bullet as it exits the firearm. - The Magazine is a storage area for ammunition and is not directly involved in firing the bullet. - The Scope is an optical device used for aiming and magnifying targets, but it does not play a role in firing the bullet itself.
