Firearm components are the essential parts that make up a firearm, enabling it to function properly. Key components include the barrel, which directs the bullet; the trigger, which initiates the firing process; and the action, which loads, fires, and ejects cartridges. Other important parts are the stock, which provides stability, and the sights, which help the shooter aim accurately. Each component plays a crucial role in the operation of the firearm. For example, the firing pin strikes the primer of the cartridge, igniting the gunpowder and propelling the bullet forward. Understanding these components is vital for safe handling and maintenance of firearms.
