The Carlson Shotgun Magazine Extension Assemblies 8-shot Remington 870/1100 is a field-proven magazine extension designed for operators and hunters who demand additional firepower without replacing their existing shotgun platform. This extension allows your Remington 870 or 1100 pump or semi-auto shotgun to achieve a total capacity of 8 rounds, which includes 7 rounds in the magazine and 1 in the chamber, enhancing your engagement capability in tactical, home defense, or hunting scenarios where extra rounds are crucial.
Constructed from blued solid steel, the extension tube threads directly onto your existing magazine cap—no gunsmithing required. It includes a spring base clamp assembly and a high-visibility follower, which aids in reliable round stacking and provides visual confirmation of magazine status. The threaded design allows the extension to seat flush and secure, maintaining the shotgun's balance and reliability under repeated cycling.
Law enforcement, military personnel, and civilian operators using Remington 870 or 1100 shotguns will appreciate the added capacity for patrol, breaching, or sustained engagement. The durable steel construction ensures longevity in harsh environments, while the blued finish resists corrosion and matches factory Remington aesthetics. Installation follows straightforward instructions, making this upgrade accessible to shooters of all experience levels.
