TacStar Magazine Extension Remington 870 +5 Rounds

The TacStar Magazine Extension for Remington 870 shotguns adds five rounds to your tubular magazine capacity, extending your capability for home defense, competition, or tactical applications. This extension replaces your factory magazine cap and spring with a longer tube and higher-capacity spring system, allowing you to keep more shells on board without reloading.

Manufactured from durable aluminum with a matte black finish that matches most Remington 870 configurations. Installation is straightforward for anyone comfortable with basic shotgun disassembly—requires removal of the barrel and factory magazine spring/cap, then installation of the extended tube, new spring, and retention system. No permanent modifications to the firearm are required. The extension maintains reliable feeding when properly installed and used with appropriate ammunition.
