The ERMOX XDEFENSE RX from Adams Arms is a semi-automatic 12-gauge shotgun built around an Auto-Regulating Gas-Operated (ARGO) system with a short-stroke dual-piston design. The configuration places the gas port forward of the chamber to reduce fouling and promote reliable cycling. Pistons act directly on the bolt for faster operation with minimal vibration, and the platform includes tactical features such as a pistol-grip skeleton stock, a ported barrel, and a 5+1 magazine capacity.
