What is the name of the part of a firearm that allows the bullet or shot to travel after firing?

The barrel is the part of a firearm that allows the bullet or shot to travel after firing. It is a long, metal tube that guides the projectile as it exits the firearm, and it plays a crucial role in the accuracy and velocity of the shot. The design and length of the barrel can significantly impact the performance of the firearm, including how tightly the bullet is grouped when fired and how quickly it leaves the muzzle.

The other parts mentioned have different functions within the firearm. The cylinder is specific to revolvers and holds the rounds in place before they are fired. The stock is the part of the firearm that provides stability and support for the shooter, assisting in aiming and control. The action refers to the mechanism that loads, fires, and ejects the cartridge. Each component is essential to how a firearm operates, but it is the barrel that is specifically responsible for directing the trajectory of the bullet after ignition.
