What do the barrel, receiver and bolt do?
The barrel guides the bullet. In a rifled barrel, its internal profile also gives the bullet spin. In conventional rifles, the chamber is at the rear of the barrel and holds the cartridge. The receiver connects important assemblies and houses moving parts of the action. The bolt or breech mechanism closes the system according to its design.

In a manually operated repeating rifle, the shooter moves the action by hand. A self-loading rifle uses some of the energy available during firing for the next loading cycle. These different operating methods do not, on their own, tell you which rifle is more precise. What matters is the complete system, including manufacture and condition.
Terms such as locking, barrel attachment and action stiffness describe individual aspects. One particularly high-quality part cannot replace a well-matched overall design. Even connections that look similar can differ technically. Work on components exposed to firing pressure requires professional assessment; an apparent physical fit is not enough.
