Overview
Designed for hunters and shotgun owners who want added magazine capacity, this extension replaces the magazine cap and threads onto compatible tube-fed shotguns. It is constructed of blued solid steel and includes a spring, base clamp, and high-visibility follower for a complete installation package. The included instructions help simplify setup, while the listed capacity reflects use with 2 3/4" shells and one shell in the chamber. Compatibility is limited to the specified Remington 870/1100 and Benelli tube-mag models, and some newer Remington setups require removal of tabs in the original magazine tube.

Considerations & Trade-offs
- Capacity is listed as total capacity with 2 3/4" shells and one shell in the chamber, so the round count shown is not the same as magazine-only capacity.
- The extension replaces the magazine cap, so installation changes the shotgun’s original configuration rather than adding a standalone accessory.
- Remington 870/1100 fitment may require removal of tabs in the original magazine tube on newer models.
- Availability is limited to Remington 870/1100 and Benelli shotguns with a tube magazine, so compatibility should be confirmed before purchase.
