Ermox X-Defense Semi Auto 18.5" S/A SG Tactical Shotgun

This tactical semi-automatic shotgun is built for reliability in the harshest environments, featuring an advanced Auto-Regulating Gas-Operated (ARGO) system. The unique dual-piston, short-stroke action is self-cleaning and minimizes fouling, ensuring consistent, rapid cycling. With gas ports positioned just ahead of the chamber, operation remains smooth and clean, while dual pistons push directly on the bolt for faster, low-vibration performance—eliminating the need for heavy action bars or connecting linkages.

Outfitted with a durable black synthetic stock and a textured pistol grip for superior control, this shotgun is marine-tough and ready for any mission. The 18.5″ barrel is equipped with an adjustable ghost ring rear sight, fixed blade front sight, and standard M choke tube. An integrated Picatinny rail makes it easy to add optics or accessories.
