Featuring the Inertia-X Drive system, the EAA Girsan MC312 Tactical Semi-Auto Shotgun is earning a reputation for extreme reliability. The action is incredibly reliable, requiring no adjusting…ever. It runs cooler and cleaner than gas systems, allowing the gas, and burnt powder to move out of the barrel freely, which means less maintenance required. With only 3 main parts, it's one of the simplest-yet-strongest systems on the market. Each MC312 undergoes extensive individual quality control tests from Girsan before shipment to ensure proper function. Plus, it comes from the factory with a red dot optic for lightning-fast targeting. Raised rifle-style front sight. Polymer stock and forend. Enhanced loading port for faster loading.
