Wilson Combat SGETRH1 Extension Tube 12 Gauge 1-Rd Parkerized Steel - Remington 870/1100/11-87 Right Hand

The Wilson Combat SGETRH1 Extension Tube is a 1-shot magazine extension purpose-built for 12 gauge Remington 870, 1100, and 11-87 shotguns. Machined from steel and finished in a rugged Parkerized black coating, this right-hand extension replaces the factory magazine tube to add one additional round of capacity while preserving the feeding reliability these classic Remington actions are known for.

Part of Wilson Combat's One Shot Tactical line, the SGETRH1 is designed as a direct replacement magazine tube for shooters running these Remington platforms in tactical, defensive, or sporting roles. The steel construction and parkerized surface deliver a durable, corrosion-resistant finish, and the right-hand configuration is tailored to the standard magazine-tube orientation on the 870, 1100, and 11-87.

The SGETRH1 is built around an extra-power magazine spring for improved reliability with the added capacity. Installation requires basic gunsmithing knowledge and standard tools; Wilson Combat publishes a dedicated installation video for this extension tube. Once fitted, the extension provides a clean, durable capacity upgrade that keeps the shotgun's balance and pointability while giving the operator one extra round on tap.
