Core Components of the Bolt Assembly
* Bolt Carrier: The main body that houses other components.
* Bolt Head: Contains the firing pin and locking lugs.
* Firing Pin: Strikes the primer to ignite the cartridge.
* Extractor: Removes spent casings from the chamber.
* Ejector: Kicks the spent casing clear of the weapon.
* Cam Pin: Controls the rotation and locking of the bolt.
* Retaining Pin: Secures the firing pin in place.
Advanced Principles of Operation
The bolt assembly operates on a principle of controlled explosion. The expanding gases from the ignited cartridge force the bolt rearward, unlocking it from the barrel extension and initiating the extraction and ejection cycle. The timing of this sequence is critical for reliable operation.
Imagine the process as a carefully choreographed ballet. Each movement, from the initial chambering of the round to the final ejection of the spent casing, is precisely timed and executed. Any deviation from this choreography can disrupt the entire sequence.
