Which phase follows chambering in the cycle of function?

The phase that follows chambering in the cycle of function is locking. After a round is chambered, it is crucial for the weapon's mechanisms to secure the round in place, ensuring that it is properly aligned for firing. Locking involves the engagement of the bolt with the barrel, which provides the necessary stability and safety for discharging the ammunition. This process is vital for preventing any potential malfunctions during firing, as an improperly locked round may result in issues such as failure to fire or unwanted movement of the cartridge. Therefore, understanding the locking phase is essential, as it confirms that the firearm is ready to operate safely and effectively.
