What follows firing in the cycle of operations for the M870?

In the cycle of operations for the M870 shotgun, the step that follows firing is unlocking. This process involves the disengagement of the bolt from the barrel so that the spent shell can be ejected and the next round can be loaded into the chamber. Unlocking is crucial as it prepares the firearm for the next operation, ensuring that the bolt can move freely to allow for extraction of the spent cartridge.

In the context of the M870, after firing, the bolt must unlock to provide access for the extraction process. This is a fundamental part of semi-automatic and pump-action shotguns, where the movement of the bolt is essential for cycling through the ammunition effectively. Understanding this sequence is important for maintaining the reliability and effectiveness of the weapon during use.

The other steps in the cycle, such as extracting or loading, occur after the unlocking step; thus, they depend on the successful completion of unlocking for the operational sequence to continue smoothly.
