Wilson Combat 1-Shot Magazine Extension Tube – 12 Gauge Right-Hand Thread, Black

This Wilson Combat magazine extension tube adds one additional round of 12-gauge capacity to compatible shotguns. Designed for shooters who need extra firepower without excessive barrel extension, this single-shot extension provides a practical capacity increase for home defense, competition, or tactical applications. The right-hand thread configuration ensures compatibility with most standard 12-gauge shotgun magazine tubes.

Machined from steel with a durable black finish, this extension tube resists corrosion and maintains a clean profile. Installation requires removal of the existing magazine cap and spring retainer—basic gunsmithing tools and familiarity with shotgun disassembly are recommended. Verify thread compatibility and barrel clearance before installation, as some barrel lengths may not accommodate extensions safely.
