Wilson Ext Tube 1-shot 12ga Rh Blk

The Wilson Combat Extended Tube 1-shot 12 gauge Right-Hand Black is a magazine extension purpose-built to increase shotgun capacity and operational flexibility in demanding environments. Derived from Scattergun Technologies' combat-proven design—selected for duty by the U.S. Secret Service and U.S. Border Patrol—this extension tube adds one round to standard magazine capacity, bringing most 12-gauge platforms to five-round configurations. The right-hand sling mount is positioned on the left side of the tube, enabling the operator to deploy a two-point sling while maintaining full access to the charging handle and controls.

The tube ships with an extra-power magazine spring engineered to compress and cycle heavier ammunition loads reliably, reducing the risk of short-stroking that can occur with aftermarket extensions. The black finish resists corrosion and provides a professional appearance consistent with tactical and law enforcement specifications. At 7.5 inches in length and weighing only 0.44 pounds, the extension adds minimal overall length while distributing weight low on the platform, maintaining handling characteristics during rapid transitions and positional shooting. Installation integrates seamlessly with standard shotgun magazine tube systems.

This extension serves operators requiring increased round count for patrol duty, entry operations, or training scenarios where reload frequency impacts mission effectiveness. Law enforcement agencies evaluating magazine extensions prioritize proven reliability under stress—the U.S. Secret Service and Border Patrol endorsement speaks directly to real-world performance in high-consequence environments. Right-hand shooters utilizing two-point sling systems will find the left-side mount geometry standard for primary weapon configurations.

Magazine extensions for 12-gauge shotguns remain a niche category dominated by Scattergun Technologies' industrial-grade design. Compatibility varies by platform, so verify fitment with your specific shotgun model before purchase. The combination of battle-proven design, U.S. government service record, and included high-power spring makes this extension a reference point for evaluating competing products in the category.
