What is the tube-like part through which bullets travel in a firearm?

• A. Barrel
• B. Chamber
• C. Receiver
• D. Magazine

Answer: (A)

The tube-like part through which the bullet travels is the barrel. It is the long hollow tube that guides the bullet from the chamber to the muzzle after ignition, and in rifled barrels, the grooves inside impart spin for stability during flight. The chamber is the rear area where a cartridge sits before firing, the receiver is the gun’s main structure that houses the action, and the magazine stores rounds to feed into the chamber. So the element the bullet passes through is the barrel.
