In the functioning of the M4 rifle, what step follows the unlocking?

After the unlocking phase in the functioning of the M4 rifle, the next step is extracting. During this process, the extractor claw engages with the rim of the cartridge case, which allows the spent casing to be pulled out of the chamber. This is a critical step to ensure that the rifle can cycle properly and prepare for the next round to be chambered.

Extracting is important because if the spent cartridge is not removed from the chamber, it could cause a malfunction, preventing the weapon from firing. This process sets the stage for the subsequent steps, such as ejecting the spent casing and feeding a new round into the chamber, which are essential for maintaining a functional and operational weapon. Understanding the order of these steps is crucial for anyone working with the M4 rifle to ensure effective handling and maintenance.
