Which are the three main parts of a shotgun?

The three main parts of a shotgun are the barrel, action, and stock, making the correct answer accurate for understanding shotgun construction.

The barrel is the long, metal tube through which the shot travels when the gun is fired. It is essential for directing the projectile accurately towards the target. The action refers to the mechanism that loads, fires, and ejects the shells, encompassing various components such as the trigger mechanism and the chamber where the shell is held before firing. The stock is the part of the shotgun designed to be held against the shoulder; it provides support and stability when aiming and firing.

Understanding these components is crucial for effective operation and safety while using a shotgun. The barrel, action, and stock work together to ensure the firearm functions properly and is manageable for the shooter.
