Scattergun Technologies 2-Round Magazine Tube Extension for Remington 870/1100/11-87 12 Gauge - Parkerized Finish

The Scattergun Technologies 2-round magazine tube extension for Remington 870/1100/11-87 shotguns is purpose-built to add two more rounds to your 12 gauge's magazine capacity. Built with the uncompromising quality that earned selection by the U.S. Secret Service and U.S. Border Patrol, this parkerized extension handles the demands of tactical, home-defense, and serious hunting applications where extra ammunition on tap matters.

Installation is straightforward—the extension ships ready to drop in with all necessary components included. The package comes with an extra-power magazine spring designed for reliable feeding under stress, and a high-visibility neon green follower that lets you see at a glance when your tube runs dry. The wave washer is included as well, ensuring proper fit and function right out of the box.

Scattergun Technologies engineered this extension from only the strongest materials to withstand rough handling and repeated use without failure. The parkerized finish stands up to weather and corrosion, making it suitable for field conditions or hard use. One note for owners of newer 870 magazine tubes: the follower is not grooved for those newer designs; the detent in your magazine tube may need to be filed down to accommodate it.
