Lyman 1082231 Plus 2 Magazine Extension Fits Remington 870 Black Aluminum

The Lyman 1082231 Plus 2 Magazine Extension for Remington 870 shotguns adds practical capacity and reliability to one of America's most trusted pump-action platforms. Built from 6061 aluminum and finished in anodized matte black, this extension tube is engineered to handle the demands of hunting, sport shooting, and tactical applications. Whether you're running clay courses, hunting waterfowl, or working a home-defense setup, gaining two additional rounds in the magazine tube makes a real difference when it counts.

The modular design here is worth noting: both ends feature identical threading, which means you can reverse the tube to reposition the magazine/barrel clamp recess to suit your setup and accessories. That flexibility matters when you're building a shotgun that works exactly how you want it. The extension comes with a high-visibility follower to help you track round count under pressure, and it accommodates a long magazine spring that lets you dial in fit and function to your specific Remington 870 and ammunition combination.

Machined aluminum keeps weight down while delivering the strength needed for serious use. The matte black finish integrates cleanly with modern shotgun builds and resists glare. This is a straightforward, no-nonsense capacity upgrade for 870 owners who want reliable performance without complications.
