Overview
This Wilson Combat SGETRH1 Magazine Extension Tube is engineered to enhance the operational capacity of 12 gauge Remington M870, 1100, and 1187 shotgun platforms. It directly integrates, extending magazine capacity and improving overall utility for tactical and competitive applications.
Key Features
Capacity Augmentation
The extension tube is specifically designed to increase the shotgun’s magazine capacity by two rounds, bringing the total capacity to six rounds. This augmentation provides a significant increase in on-board ammunition, reducing reload frequency during high-tempo engagements.
Reliability and Positive Feedback
Supplied with an extra-power magazine spring, this system ensures consistent and reliable feeding across the extended capacity. An integrated high-visibility follower provides immediate visual confirmation of an empty magazine tube, critical for operational awareness during reloads and tactical checks.
Construction and Finish
Constructed from robust steel, ensuring durability and resistance to operational stressors and impact. The tube is finished with a Parkerized black coating, offering advanced corrosion resistance and a low-glare, non-reflective surface that integrates seamlessly with most firearm finishes.
Ergonomics and Utility Integration
Features a purpose-built sling mount positioned on the left side of the extension tube. This design facilitates sling attachment for right-handed shooters, optimizing weapon retention and carry options without interfering with the weapon’s action or field stripping.
