Bolt-action rifles primarily utilize a manually operated mechanism where the shooter manually cycles the bolt to feed a cartridge into the chamber, fire the round, and then extract the spent casing. This action type is distinct from others because it relies on the physical manipulation of the bolt handle by the shooter rather than gas pressure or recoil force to operate.

The bolt-action mechanism is known for its reliability and accuracy, as well as the ability to lock the bolt securely into the chamber for enhanced safety and precision. Additionally, this type of action allows for a simpler design with fewer moving parts, which can improve ease of maintenance and longevity of the firearm. The shooter has direct control over the cycling of the action, which can lead to decreased chances of malfunctions due to the absence of more complex operating systems found in semi-automatic or automatic firearms.

In contrast, the other action types mentioned rely on different principles of operation, emphasizing the unique nature of bolt-action rifles in the context of firearm mechanics.
