What are the three main parts of a firearm?

The three main parts of a firearm are indeed the action, stock, and barrel. The action is the mechanism that ejects cartridges, loads new ones, and fires the gun; it is crucial for the operation of the firearm. The stock provides support and stability, allowing the shooter to hold and aim the firearm effectively. The barrel is the long metal tube where the bullet travels when fired, and it also helps direct the bullet's path and influences accuracy.

Each of these components plays an essential role in the functionality of the firearm. The action is what allows the gun to cycle and fire, the stock helps maintain control, and the barrel is key for delivering the projectile accurately toward the target. Understanding these parts is fundamental for anyone learning about firearms, as this knowledge aids in safe handling, maintenance, and operation.
