What is the muzzle of a bolt-action rifle?

The muzzle of a bolt-action rifle refers to the end of the barrel where the projectile exits when fired. This part of the rifle is critical because it directly influences the trajectory of the bullet as it leaves the firearm. The design and condition of the muzzle can affect accuracy and the overall performance of the rifle. Understanding the components of a rifle, including the muzzle, is essential for safe handling and effective shooting practices. The other choices pertain to different parts of the rifle that serve distinct functions: the trigger mechanism controls firing, the ammunition is held in the chamber or magazine, and the trigger guard is a safety feature that protects the trigger from accidental discharge.
