Overview
The Wilson Combat Extension Tube enhances the operational capacity and versatility of compatible Remington 870, 1100, and 11-87 12-gauge shotguns. Engineered for robust field performance, this +1 round magazine extension integrates seamlessly, providing increased ammunition reserves critical for tactical applications, competition, or defensive use.

Key Features
Optimized Capacity and Reliability
- Increases shotgun magazine capacity by one round, optimizing operational readiness.
- Includes an extra-power magazine spring to mitigate feeding issues and ensure consistent cycling, even during rapid fire.
- Supplied with a high-visibility, fully machined neon green follower to facilitate positive feeding and provide immediate visual confirmation of an empty magazine tube.
Integrated Sling Attachment Point
- Features a Quick Detach (QD) sling stud positioned on the front of the extension tube, enabling rapid and secure attachment of a sling system without additional hardware. This enhances weapon retention and carry options.
Durable Construction
- Constructed from high-strength materials engineered for maximum resilience against impact and rough handling.
- Finished with a durable black Parkerized coating, providing superior corrosion resistance and a non-reflective surface.
Installation Notes
- Designed for straightforward installation. A wave washer is included to ensure a secure fit.
- Important: The included follower is not grooved to accommodate newer Remington 870 magazine tubes equipped with an internal detent. For proper fitment in these newer models, the magazine tube detent may require professional modification (filing).
