What is the main function of the shell lifter in the Remington Model 870?

The main function of the shell lifter in the Remington Model 870 is to efficiently feed shells from the magazine into the chamber of the shotgun. This component is crucial for the operation of the shotgun, ensuring that each time the action is cycled, the next shell is lifted into position, ready to be chambered for firing. The shell lifter performs this task by raising the shell from the magazine tube as the action is opened, allowing a smooth and reliable transition of the shell into the chamber. This mechanism contributes significantly to the firearm's overall reliability and functionality during operation, enabling shooters to perform quick follow-up shots without delays in reloading. The importance of the shell lifter highlights the design and engineering of the Model 870, making it a favorite among users for both sport and law enforcement applications.
