What are the three basic parts of a modern firearm?

The three basic parts of a modern firearm are the barrel, stock, and action.

The barrel is the part of the firearm through which the projectile is fired. It provides a pathway for the bullet, and its design can significantly influence the accuracy and velocity of the projectile as it leaves the gun.

The stock is the part that the shooter holds and stabilizes the firearm. It serves as the framework to which the other components are attached and provides the necessary structure for aiming and shooting effectively.

The action encompasses the mechanisms that load, fire, and eject ammunition. This includes components that facilitate the firing sequence and interact with the cartridge and projectile.

These three parts work together to ensure the firearm operates correctly and safely, making them fundamental to any modern firearm's design and functionality.
