TacStar Magazine Extension for Remington 870 – +3 Round Capacity

The TacStar Magazine Extension for Remington 870 shotguns adds three additional rounds to your firearm's capacity, extending effective use for home defense, competition, or tactical applications. This extension replaces the factory magazine cap and extends the magazine tube forward beneath the barrel, allowing you to carry more shells without modifying the receiver or requiring a different magazine tube assembly.

Constructed from durable aluminum with a black anodized finish, this extension is designed for long-term reliability and corrosion resistance. Installation requires removal of the barrel and factory magazine cap, then threading the extension onto the existing magazine tube. A new magazine spring and follower are included to ensure reliable feeding with the extended capacity. Professional installation is recommended if you are unfamiliar with shotgun disassembly and magazine tube components.
