1. Functionality
Functionality of the Remington 870 20 gauge forend tube assembly is directly tied to the shotgun’s action cycling process. This assembly houses the action bars, which connect the forend’s pump motion to the bolt. When the forend is pumped rearward, the action bars retract, unlocking and opening the breech. This ejects the spent shell. Pushing the forend forward then chambers a fresh round, closing and locking the breech, preparing the shotgun for firing. Any malfunction within this assembly directly impacts the firearm’s ability to cycle and fire. A bent or damaged tube, worn action bar lock, or a broken forend spring can all lead to failures to feed, extract, or eject shells. In a hunting or self-defense scenario, such failures can have serious consequences.
The smooth operation of this component is crucial for reliable feeding and extraction. Binding or excessive friction within the tube can slow down or prevent the action from cycling properly. For example, a build-up of dirt or debris, or a lack of lubrication, can impede the movement of the action bars within the tube. This highlights the importance of regular cleaning and maintenance. Furthermore, the forend tube assembly’s design contributes to the overall ergonomics of the shotgun. A properly fitted and functioning assembly allows for comfortable and efficient pump action, enabling quick follow-up shots and enhancing overall handling.
Understanding the functionality of this assembly underscores its critical role in the shotgun’s operation. Regular inspection and maintenance are vital to ensure continued reliability.
